Doosan customer success stories


Doosan continues to deliver an impressive selection of heavy equipment with the launch of several new excavators — crawler and wheel — and wheel loaders featuring numerous system and performance improvements. Advancing product lines beyond the delivery of interim Tier 4 (iT4) compliance, Doosan evaluated markets and listened to customers about what they need to be more productive. The results are exceeding customer expectations.

>>> Crawler exCavatorsContinuous improvements and updates to Doosan excavators provide operators with more power, performance and speed. New Doosan iT4-compliant machines have also been upgraded to allow operators to customize the excavator to a variety of working conditions found in rental, site development, commercial construction and highway/street development applications.

Updated Doosan excavators are equipped with a new electronic fan clutch, reducing fuel consumption and noise levels, while providing cooling system efficiency improvements on the machines. Newer Doosan excavators also include an Electronic Power Optimizing System (EPOS), four power modes, four work modes, auto idle and machine diagnostics. Operators can work more effectively with multiple work modes, easy-to-read display monitors and precise control levers. The new Power+ mode provides improved performance and faster workgroup speeds for heavy-duty work.

Four work modes — digging, lifting, breaker and shear — allow operators to get maximum efficiency and fuel economy in specific applications. In the lifting mode, the increased pump torque, low engine RPMs and automatic power boost provide extra muscle when lifting materials like pipe or concrete barriers.

Intelligent Floating BoomA new Intelligent Floating Boom option allows the boom of the Doosan excavator to “float” up or down, letting the operator focus more on the task while decreasing the machine workload and increasing efficiency.

Straight travel, increased speedA new straight travel option streamlines the travel and transport of the Doosan excavators. This feature is ideal for the straight forward and backward travel, which is common in trenching applications. It provides a single foot pedal in the right front corner of the cab floor that operates both tracks. Additionally, the new machines provide speed improvements, offering more efficient movement around jobsites.

Enhanced operator comfortDoosan continues to focus on operator comfort with further enhancements to the Roll-Over Protective Structure (ROPS) cabin. The door window position slider now locks in various positions, preventing it from moving from its intended location. The door space of the cab has increased by 1.8 inches, allowing the operator to get in and out more easily. The cabin size has increased 6.1 percent, providing more headroom. The joystick angle has been reduced from 25 degrees to 19 degrees to provide a more ergonomic profile and decrease interference with operators’ legs.

Additional cab updates include both a height lever and tilting function for the air suspension heated seat to allow the operator to find an optimum seating position. The cabin mounting mechanism has been improved with a thickened dampening plate, and an internal coil spring has been added to reduce cabin vibration 20 percent, allowing operators to work longer days with less fatigue.

>>> New DoosaN wheel loaDers eNhaNCe performaNCe aND operator ComfortUpdated Doosan wheel loaders feature improvements in performance, serviceability and operator comfort.

Performance updatesEquipped with an interim Tier 4 compliant (iT4) diesel engine, new Doosan wheel loaders have increased horsepower and lift capabilities for enhanced performance, helping operators get more work done in less time. Newer Doosan wheel loaders are also more fuel-efficient, helping owners reduce costs and improve profits.

A hydraulic locking differential is available as an option to the standard limited slip differential. The optional hydraulic locking differential may be locked manually or automatically, based on ground conditions.

Newer Doosan wheel loaders are equipped with auto idle for additional noise reduction and fuel savings. The feature reduces the working idle of the wheel loader by 200 rpm when the machine is inactive for a short period of time. Conversations between the wheel loader operator and other employees are much simpler, thanks in part to auto idle.

Doosan wheel loader operators have the ability to set upper and lower limits for the lift arm stop positions from inside the cab rather than setting them outside. This feature is great for working in height-restricted structures (setting max. height) or repetitive tasks such as truck loading to increase productivity.

Another common option for select Doosan wheel loaders is a torque converter lockup clutch. This enables the machine to climb grades easier and faster, increasing productivity as much as 20 percent in certain stockpiling applications.

More new options for Doosan wheel loaders include a diesel-powered coolant heater to improve starting in cold weather or a block heater that warms the engine coolant before engine startup with an electrical heater.

ServiceabilityProperly maintaining equipment ensures its longevity. That’s why Doosan wheel loaders have easy-to-access routine service items, such as fluids and filters, to help owners and operators perform daily maintenance checks.

The new automatic reversing cooling fan can be set to run in reverse to assist in keeping the cooling system clean. The operator can reverse the fan by activating a switch, or it can be set to automatically reverse on a preset time frame. This is particularly helpful in agriculture applications where hay and other debris can quickly build up in the cooling system.

Enhanced comfortInterior cabin improvements also include a number of multi-function display panel upgrades on a centralized monitor that allow the operator to view comprehensive machine system information — such as engine rpm, engine coolant temperature, fuel level, DEF level, machine warnings, time and the transmission selected gear.

Operators can quickly glance at all key switches with the application of a window decal containing all switch icons, and description of their function. A vital exterior cabin improvement is lowered front-side glass, providing improved visibility of operations.

With a focus on increasing cab comfort for operators, optional electric steering decreases operator fatigue during repetitive cycle operations on the jobsite. A joystick has been added to the left armrest that allows the operator to control the directional movement without having to use the steering wheel. A new door threshold makes getting in and out of Doosan wheel loaders — and cleaning the inside of the cab — much easier.


Doosan is expanding its excavator attachment offerings with two new hydraulic breakers. The Doosan DXB130H and DXB190H hydraulic breakers feature an energy recovery system that increases strike power for maximum productivity in a variety of demanding applications.

The nitrogen-powered breakers are equipped with an upper/lower suspension system that isolates the power unit from the housing. The energy recovery system captures the piston’s rebound energy and uses it to increase strike power, maximizing performance. Blank-fire protection is standard on the DXB130H and DXB190H and is accomplished by using a cushion of oil at the base of the piston, which reduces the metal-to-metal contact in case of a blank fire situation.

Two-speed control: DXB190HThe DXB190H is engineered with Doosan’s two-speed control, which also is available on the DXB260H breaker. With two speeds, the DXB190H breaker

frequency can be manually adjusted between low and high frequency settings. This allows the operator to match the breaker impact rate to the working conditions for optimized productivity.

Match a tool to the projectDelivering up to 600 blows per minute, the 2,822-pound DXB130H is designed for use with excavators in the popular 15- and 22-metric-ton weight range. Rated in the 3,000 ft.-lb. impact energy class, the DXB130H requires a hydraulic flow rate of between 23.8 and 37 gallons per minute.

Delivering up to 360 blows per minute in its low frequency setting or 540 blows per minute in its high frequency setting, the 3,698-pound DXB190H is designed for use with excavators in the popular 21-to-31 metric-ton weight range. The DXB190H is rated in the 6,000 ft.-lb. impact energy class and offers a hydraulic flow rate of between 31.7 and 47.5 gallons per minute.

Protect and performThe breakers’ suspension system extends excavator workgroup life by absorbing harmful vibrations and stress waves. Also, a patented main valve design reduces hydraulic pressure peaks that can reduce pump life, crack excavator workgroup welds and cause system overheating.

The cradle-mounted grease station delivers continuous grease flow, reducing bushing and tool wear while minimizing maintenance costs and downtime. The DXB130H and DXB190H breakers also come with a mounting cap, auxiliary hydraulic hoses, two moil points, toolbox and a nitrogen checking device.

In addition to the general purpose moil, working tools available for Doosan’s new breakers include a blunt tool, a chisel and a pyramidal or “nail” point. A one-year limited warranty is standard on these breakers.

To enhance your preferences for wheel loader attachment change mechanisms, Doosan has expanded its hydraulic coupler line with the addition of ISO-style couplers.

The ISO-style coupler is compatible with Doosan general purpose, light material and multi-purpose buckets, as well as the four models of pallet forks that are available for all Tier 3 and iT4 wheel loaders. These attachments are constructed with heavy-duty materials and are available in a variety of styles and configurations to add versatility to Doosan’s wheel loader line. See the descriptions below for more details.

The downtown business district of Iowa’s vibrant capital city is dissected from east to west by the Des Moines River, a 525-mile-long tributary of the great Mississippi, and the longest river flowing through the state. Named for Iowa’s largest city, the Des Moines River has long beckoned tourists to the downtown area for a variety of festivals, celebrations and entertainment venues. Now, a recent infrastructure improvement project promises to further enhance the downtown experience, affording visitors the opportunity to traverse

both banks of the river for walking, jogging, biking and blading, or dining at one of several planned riverfront restaurants.

The Principal Riverwalk is a multi-year, downtown improvement initiative jointly funded by the City of Des Moines, the State of Iowa, U.S. Army Corps of Engineers, Federal Highway Administration and Principal Financial Group, one of the city’s largest employers. When complete, the Principal Riverwalk will feature a 1.2-mile

Des Moines sewer project underscores commitment to infrastructure, flood controlDoosan excavator plays a key role in the installation of a much-needed sewer upgrade — in tight

quarters — within the capital city’s vibrant downtown business and entertainment district

recreational trail connecting the east and west sides of downtown via two pedestrian bridges,

and a 12-foot-wide multi-use trail along the barrier at river level for joggers and bikers. Night-time lighting and security will turn the river loop into a 24/7 attraction as downtown Des Moines prepares to take on a new and exciting recreational role.

The expansion-infrastructure equationPlanning officials agree that while city expansion projects — especially those designed to attract tourists — are exciting and beneficial for municipalities, new development can also place additional strains on existing infrastructures, especially storm water and sanitary sewer services. The Des Moines Riverwalk project is no exception. Yet advance planning by city engineers and cooperative efforts among all parties afforded officials the opportunity to incorporate a much-needed upgrade to aging sewers while addressing an ongoing threat posed by the river nearly every spring — flooding.

After the historic flood of 1993, earthen berms and levees — many of which had failed to protect the downtown area — were raised and reinforced. And while the levy enhancements proved effective in containing the rising water within the river’s banks during a subsequent flood event in 2008, the aged, inadequate storm water sewer system was unable to prevent flood waters from backing up into the downtown area again,

surrounding many businesses. So city officials focused on developing a solution.

Coined the Court Avenue and Water Street Sewer Separation Project (no coincidence that Water Street runs parallel to and within a few feet of the Des Moines River), city officials unanimously approved nearly $10 million in funding to address the inadequacies of the existing sewer system. The project includes the construction of storm sewer along Court Avenue from Water Street west to 2nd Avenue; then north three blocks to Grand Avenue, and west again to 3rd Street — a distance stretching approximately six blocks.

The larger storm sewer was specified as RCPP; a reinforced concrete pipe with a gasketed joint. The deeper sewers are below the river level and will always have infiltration into the pipe. Also, during high river levels, the pipe will become pressurized. Therefore, the gasketed pipe will reduce the infiltration and material being conveyed into the pipe through the joints.

The first phase from Water Street along Court Avenue and north up to Grand Avenue was completed on schedule in fall 2011. H & W Contracting selected subcontractor Rognes Excavating, based in Ankeny, Iowa, to install the storm sewer portion. The open-cut method identified for the majority of the project was influenced mostly by cost. Yet there were also locations along the sewer alignment in which open-cutting the pipe was not feasible; hence five trenchless installations were completed along the project.

RTL equipment recommended the Doosan DX235LCR excavator for the job mainly because of its near-zero clearance capabilities. This excavator has just 3 inches of overhang and has the ability to maneuver within inches of construction barriers. — warren rognes, Rognes Excavating

Doosan excavator onsiteRognes Excavating worked with RTL Equipment to secure a Doosan DX225LC and DX235LCR crawler excavator to complete the trenching and installation of the 66- and 54-inch reinforced concrete pipe (RCPP) sewer. The RCPP along Court Avenue is all 66-inch diameter, while the pipe diameter reduces at 2nd Avenue to 54-inch for the extent of the upstream pipe.

“There were confined space and lane width considerations given that this is a high-traffic, often-congested downtown area,” Warren Rognes says. “RTL equipment recommended the Doosan DX235LCR excavator for the job mainly because of its near-zero clearance capabilities. This excavator has just 3 inches of overhang and has the ability to maneuver within inches of construction barriers. It fits well into tight spaces and has less tail swing radius.”

“Aside from the compact frame and extended reach, it’s also easy to perform daily maintenance on the DX235LCR,” Rognes says. “All of the routine maintenance points are easily accessible, allowing us to complete daily maintenance more quickly, and keep the machine

running most efficiently. The DX235LCR also has extended vertical reach that requires repositioning the excavator less often. The extended arm reach is also capable of loading spoil into high-frame truck boxes.”

Subsurface exploration was critical. As a result, there were no delays due to utility conflicts. Communication was also an important component to the project’s success. Contractors, businesses and media were kept informed continuously, not just about specifics of the project, but also of progress and delays.

“Aside from some unavoidable traffic backups and congestion during peak times and a few minor, unsightly inconveniences to the thousands of Downtown Farmers Market goers, the project went really well,” says David Kamp, an engineer with the city and instrumental in the design of the project. “Contractors, workers and the city tried to minimize inconvenience and mitigate the occasional frustration of drivers and downtown pedestrian traffic, but some of the challenges were simply unavoidable. The vast majority of Des Moines residents are unaware of just how significant this project really is, or what has taken place underground that now makes the downtown area safer from flooding. It really is an out-of-sight, out-of-mind sort of thing.”

He’s regularly evaluating his business and making changes to meet the business climate and customer expectations.

Winchester is able to keep up with customer demands with reliable equipment, including a Doosan 225LCV and S75 mini excavator that he purchased from Mesco, the local Doosan equipment dealer in Salt Lake City. With this combination of equipment and a knowledgeable staff, Winchester has become one of the area’s best excavating companies.

“We excavate for residential and commercial site development, including subdivisions, townhomes, single-family homes and commercial buildings,” Winchester says. “Two years (2009 and 2010) were pretty tough, but 2011 was the best year we ever had. I think it’s because of our ability to meet our customers’ needs. We’ve been called out to jobsites at 2 a.m. because they needed to pour concrete

at 6 a.m. We’re willing to get out and do whatever it takes, to make sure they can do their scope of work. We pride ourselves on integrity and honesty.”

A shift in his type of work has helped Winchester keep his business in the black. “We had to adapt to what was going on,” he says, responding to the declining housing market in the Salt Lake City area. “We’ve always done a little commercial, but the last two years we’ve done a lot of commercial work. We perform site development — excavating and grading — for general contractors.”

Excavating at new shopping centerIn 2011, Winchester and his employees were working at a new open-air shopping center in Farmington, Utah, called Station Park. “We were their onsite contractor and we dug a lot of foundations for new buildings, plus miscellaneous odds and ends; whatever they needed done,” Winchester says. “We did a lot of the building pad preparation and backfilling for department stores and nearby strip malls, as well as underground pipe

work and storm drains. We rented a Doosan DX225LC for use with our two excavators.”

CenterCal Properties was the retail development company in charge of constructing the new shopping center. Farmington is just north of Salt Lake City and was selected for the new shopping center because of its location along I-15/Highway 89 and the new Utah Transit Authority Commuter Rail. According to the company’s website, the new shopping center consists of approximately 800,000 square feet of retail, entertainment, restaurant, office and hotel space.

At a second commercial job in Kaysville, Utah, Winchester installed a new storm drain and sewer and water lines. The 7-metric-ton S75 Doosan excavator had the perfect amount of dig depth and reach for the utility project.

“The machine was just the right size, and the rubber tracks allowed us to go anywhere,” Winchester says. “For example, we drove across sidewalks and curbs and gutters without damaging the surface. Also, it’s a big enough machine that it will load a dump truck while

Adapting to change and exceeding customer expectations

sitting on flat ground. Due to its size and ability to get into tight places, yet have the ability to perform like a bigger machine, made it very convenient.

“The smaller excavator uses less fuel and has fewer maintenance costs, without sacrificing productivity,” Winchester adds.

In 2012, Winchester has been just as busy with commercial projects. He completed excavating and grading projects at Promontory School of Expeditionary Learning in Perry, Utah — a new K-8 charter school. “We did all of the site prep at the school,” he says. “We operated the 225LCV to remove 30,000 yards of fill dirt and loaded it in dump trucks. We did that in January, and then we created the building pad. We have multiple buckets for the excavators that we match to our excavating needs, including a 36-inch bucket for the 225LCV.”

For smaller excavating needs and final prep work, the S75 excavator is a good fit for Winchester. “Recently, we operated the S75 excavator at the school to finish-grade the site for the landscaper, and we installed some of the underground infrastructure, including sewer, water and storm drains,” Winchester says. “We have a 1-foot bucket that we use

with the S75 excavator, mainly for digging trenches for electrical conduit or when we’re working along an existing foundation.” In addition to the bucket, Winchester has a plate compactor attachment for compressing the soil when he’s done excavating.

While he was finishing the charter school construction project, he was also excavating and grading for a building pad for a new Texas Roadhouse restaurant in Layton, Utah.

Fuel savingsAs far as excavators go, Winchester has tried many brands, but Doosan rises to the top of his list. “I’ve run every brand of excavator out there,” he says, “and I have yet to get in an excavator that impresses me like the Doosan machines do. One of the biggest considerations for us is fuel consumption. The fuel consumption, compared to other brands, is far less. I’ve told my Doosan dealer numerous times that a different excavator will use 80 gallons of fuel in one day. My Doosan excavator will get two-and-a-third days out of the 80-gallon tank.”

Winchester purchased his DX225LC crawler excavator about five years ago and has logged roughly 4,000 hours. “The Doosan excavator is really smooth, with easy-to-use controls,” he

says. “I like the balance of the machine. It has plenty of power for what we use it for, and I never have to run it at full throttle. It’s just a good machine.”

Dealer supportA strong relationship with his local Doosan dealer has played a part in Winchester’s continued success. He says it was his dealer who introduced him to Doosan and lends credibility to the company’s construction equipment.

“Part of why we got involved with Doosan was because of Mesco,” Winchester says. “I’ve done business with Mesco for 20 years, and when they started selling the Doosan line, we started running them and we liked the products. We’ve used them a lot, often renting loaders and excavators. When I have friends who need a machine, I send them to Mesco. I tell them, ‘once you sit in my Doosan excavator and run it for a month, you’ll be down there purchasing one.’ I wish that I could sit in it every day, shut the door and dig.”

Maintenance mattersBlake Winchester is a firm believer in performing regular maintenance to keep all of his equipment in top shape. “We faithfully service our Doosan excavator every 300 hours, period,” he says. “That includes changing the oil and filters. It goes miles toward keeping the machine in good condition. This time of year, when it’s so dusty and hot, we’ll change inner and outer air cleaners every 150 hours. I just don’t think you can justify what a filter costs versus a major breakdown.”

The fuel consumption, compared to other brands, is far less. I’ve told my Doosan dealer numerous times that a different excavator will use 80 gallons of fuel in one day. My Doosan excavator will get two-and-a-third days out of the 80-gallon tank.

Like a familyWinchester says many of his employees have worked for him for 10 or 15 years, following him from project to project. One person in particular is his wife, Sandy. He says she has good business relationships, and that she has helped put some deals together. “I think part of our business success has been treating people right so they can live their life, too,” he says. “We try to take care of our employees. I tell them, ‘it’s not my company, it’s all our company, and it takes all of us to do our part and make it successful.’ It’s a little like family.”

With loyal employees, reliable Doosan equipment and dealer support, Winchester will be able to sustain and grow his business, and adapt to changing customer requirements.

Street smarts

When it comes to road repairs and street work, Dean Black knows his stuff. But Black’s smarts don’t start and stop simply with streets. Black defines the company he founded in 1977, Black Construction, headquartered in Devils Lake, N.D., as a complete construction management contractor that will tackle everything from utilities to landscaping.

Black’s construction instincts — especially his grading, excavation and aggregate skills — date back to childhood, and the influence of his father. The senior Black had started his own company nearly two decades before his son, who later followed in his father’s footsteps. Black has fond memories of the early days.

“My father had a small business he started in 1958,” Black says. “It was just him, a loader and a dozer. He worked really hard and never let anybody down. I would help him in the spring and summer while I was in high school, then went on the road to work for other contractors in the early to mid-’70s. He passed away the same year I started my own company, but he certainly paved the way —

no pun intended — for me to get a good start on my own.”

In the blackBlack Construction has grown considerably since its humble beginning more than 35 years ago. Today, the company ventures within a 100-mile radius of home to complete a variety of construction jobs, including site preparation, aggregate, demolition, grading, landscaping, pavement repair and utility installations. The company employs anywhere between 10 and 30 people, depending on workload and season. Things for Black slow considerably as the often ruthless North Dakota winters envelop this otherwise thriving economic climate — one of only a handful of states that currently enjoys a budget surplus and the nation’s lowest unemployment rate.

North Dakota is experiencing an energy boom similar to the one Wyoming enjoyed several years ago, and lawmakers are in the enviable position of determining which investments are most prudent for spending the state’s surplus — now estimated to be

approaching the $2 billion mark. Fortunately for companies like Black Construction, last November the state legislature allocated an extra $370 million for road repair and construction. Some $340 million will go to schools over the next two years to help reduce property taxes, while $22 million will go toward a disaster relief fund for a state that has been inundated with floods in recent years.

Among the many fortunate recipients of the state’s economic boom was the tiny community of Minnewauken (pop. 224). Situated on the shores of scenic Devils Lake, this small community realized it would be more efficient to combine elementary, junior and senior high students in one facility, and decided to move forward with construction of a new school. Black Construction was chosen to handle all site preparation, including grading, footings, utilities installation and preparing the aggregate specified to serve as the foundation of the new school’s paved parking lot. The company also engineered and installed the footings that serve as the foundation for the new school.

Black Construction


North Dakota-based Black Construction has

perfected the art of aggregate preparation

The boss of the aggregate pit is the newest wheel loader in Black’s equipment fleet — a Doosan DL300 wheel loader with 4-cubic-yard bucket. Black selected the DL300 loader after operating several Doosan loader models, as well as competitive brands, at the Doosan Real Operation Center (The ROC), just outside Tucson, Ariz.

“The DL300 loader is the ideal weight, horsepower and size for my needs,” Black says. “I also like the way it is balanced and proportioned. I had the opportunity to operate both Doosan and other manufacturers’ loaders, and the DL300 had the best torque proportion for my needs. It’s also reliable, fast and easy to operate. You don’t have to worry about spinning the wheels when trying to load the bucket; everything is proportioned just right.”

Soggy, soggy sitePerched high atop a hill overlooking North Dakota’s scenic Devils Lake, preparing the soggy hilltop school site posed greater challenges than the actual grading, foundation and utility work. Several thousand feet of drain tile — positioned

6 to 8 feet beneath the entire 80 acres — was installed first before excavation and dirt-moving equipment could even access the site and grading work could commence.

“All jobs have their own unique things, and the most unusual about this project was the wet conditions that one doesn’t normally encounter at the top of a hill,” Black says. “It’s hard to describe how the water perches itself up there, way above the water table. That had to drain for at least three months before we could even get up there to dig footings. The biggest challenge was to get access to it. Once we got things dried out, we were able to establish good roads to and from the site.”

Once drained and dried, Black’s excavation crews got to work. All told, more than 60,000 yards of dirt were scraped, loaded, hauled, replaced and leveled before the footings for the school’s foundation could be dug. Aside from the actual school building site, Black Construction was also responsible for preparing the 550-foot-long, 180-foot-wide parking lot, a process that involved installing more than 3,000 yards of gravel

aggregate fabric — including storm sewer — beneath what was to become, in its final, finished form, a smooth paved surface with the capacity to accommodate 150 vehicles.

Aggregate artThe specified aggregate was to be composed of a precise mixture of various sizes of crushed stone, sand and gravel. The first step in the art of aggregate preparation is to locate a pit for producing the gravel to the specified size. As an expert in aggregate preparation, Black is often forced to import rock or other materials to achieve specifications.

Once all of the materials have been secured, it’s a matter of crushing, measuring, blending, binding and spreading. The materials are blended together and run through a screen after the crusher. The crusher crushes the rock to desired particle size, which is then blended back in with the other gravels. A screen downsizes the mixture to ¾-inch particles, required for Class V aggregate. The mixture is then tested using the “sieve analysis with wash” testing method, which shows the percentages of the materials passing five sieve sizes.


These gradations should fall within the corresponding range for each sieve size, as outlined in the aggregate size specifications. “Once you run it [the materials] through the crusher, everything is thoroughly blended and combined,” Black says. “The aggregate is then tested by an independent laboratory to make sure the mixture meets specs. Aggregate mixing is no guessing game. It’s checked continuously to ensure every batch meets standards.”

According to Black, the Doosan DL300 was instrumental in preparing the aggregate more efficiently, allowing his crews to produce more than 1,000 yards of finished product within a typical workday. In a matter of three days, Black’s crews had loaded, crushed, mixed, blended, hauled and positioned the aggregate foundation in final preparation for a visit from the paving crew.

“Since we’ve had the DL300 loader, we don’t have to worry about keeping the aggregate plant going,” Black says. It’s got the bucket capacity, the traction, the horsepower and the quickness to keep the loading process moving forward. The cab is so comfortable and has great visibility.

This loader is an integral part of why our company operates so efficiently.”

Next up …Having recently finished their multi-task role at the school, up next for Black and his team of excavation, installation and aggregate preparation experts is a street repair gig in nearby Maddock, N.D., some 30 miles southwest of Minnewauken. This will be a return visit for Black, whose company completed a forced main line sewer job there previously.

“The street repair project in Maddock is the type of work that is really turnkey for us,” Black says. “We have the milling machines to remove the old asphalt, the excavators to dig it out, the gravel pits to make the aggregate and the rollers and dozers to apply it. So it just kind of fits us. We’ve been fortunate here that the jobs just keep coming our way. Things are booming here in the great state of North Dakota. We’ve got it pretty good up here right now.”

An ability to adapt to changing business conditions and take on new and challenging projects has helped a western Michigan construction company survive the Great Recession and continued regional economic struggles. Today, two new pieces of orange Doosan construction equipment are among the many machines on assignment for Lounsbury Excavating, Inc.

On top of the national economic crisis that crippled the United States in 2008 and 2009, Michigan has had its own set of economic challenges, most notably a decline in manufacturing in the early 2000s and again in 2008 and 2009. Michigan has one of the nation’s highest rates of unemployment. In the western part of Michigan, where Lounsbury Excavating does a majority of its earthmoving and utility projects, the unemployment rate is slightly

less than the state average. Fruit-and-vegetable operations and dairy production are traditionally strong agriculture cornerstones in these counties, which has helped keep it below the state average.

50-plus years in businessAfter returning home from World War II, Stuart Lounsbury started Lounsbury Excavating. That was 1946. He purchased some land and built an office in Paw Paw, Mich., where today Stuart’s son and grandsons keep the family-owned and operated business alive. Michael Lounsbury is the president and general manager. His sons Michael L. and Jeff run the day-to-day field operations as project manager and field superintendent, respectively.

“I’m the president of the company,” Michael says, “and I usually take care of the financial end of it. I help with some of the

more complicated parts of the work when needed. Our estimator and fourth partner is Mike Hiestand; he handles the business development and office management.”

Switch in projectsCommercial projects have always been the core of Lounsbury Excavating’s business. Since 2008, Lounsbury says it switched from private to more public projects.

“Although we’ve been pretty slow in recent years, our work has been 60 percent public and 40 percent private,” Mike says. “It used to be the opposite of that. We used to be primarily a subcontractor on jobsites. We’ve become more of what I’d call a site general contractor, where we’re managing the whole project.

“One example is where we’re taking on rebuilding parking lots and having curbs and asphalt put down. We see a lot more of that

coming along now. That’s a change for us. We’ve done a lot of school work, and replacing or installing new storm and sanitary systems, water lines and water mains. We just finished a project on a college sports complex. Currently, we are getting ready to finish a project on a county jail. We do some light, local street work but leave the highway work alone.”

New Doosan pair in 2012During the economic downturn, Lounsbury, like a lot of other contractors, did anything and everything to keep his business afloat. “We were conservative,” Mike Lounsbury says, “and I think the consistency in how we run our business has helped. We have a good handle on our costs, especially our machine costs, labor costs and fuel consumption.”

“I think our size plays a big role in our success, too, because we’re able to adapt pretty easily to the changing marketplace, with different types of equipment,” says Jeff.

Lounsbury Excavating owns an assortment of heavy construction equipment for excavating and earthmoving projects: dozers, crawler excavators and wheel loaders; some of them with as many as 18,000 hours on them.

In January 2012, new orange heavy construction equipment arrived at the Lounsbury headquarters — a DX350LC crawler excavator and a DL300 wheel loader. It was the first Doosan purchase for the Lounsbury family.

“Prior to purchasing the Doosan excavator and wheel loader, we rented a Doosan DX140LCR for a while, and then a larger 200-size crawler excavator,” Mike says. “We were among some of the first in this area to demo the Doosan excavators. Carleton Equipment has never steered us

wrong on anything.”

“When we first rented the Doosan excavator, I called him (Mike) and said, ‘you’ve got to come and try this excavator because it’s so smooth,’” Jeff says. “The controls were better than any other excavator I’d operated before. Our new DX350LC is a very smooth, nice machine.”

On a typical day, Jeff operates a machine about 50 percent of the time. He’s been able to evaluate the pluses and minuses of equipment and has well-formed opinions of their abilities. “The limited

slip differential on the DL300 is a good feature,” Jeff says, “and the DL300 easily gets into a pile and handles everything that I can give it. The cab is worlds away more comfortable than anything else we had. It has air conditioning, heated mirrors and many other perks.”

Most importantly, Jeff has seen an increase in his productivity in the Doosan DL300.

He bought a Doosan crawler excavator and wheel loader, thanks in part to a long-time relationship with his local equipment dealer.

DOOSAN


He says that in addition to the added comfort and loading abilities, it uses less fuel, too. “We’re able to do more work for the same amount of fuel, per day,” Jeff says. “Some of our other excavators and loaders are fuel-eating machines.”

Equipment tandem on projectsEarlier this year, both the Doosan wheel loader and excavator worked in tandem at a county jail project. “We did some bulk dirt-moving, over-cutting of the site to get rid of bad soils,” Mike says. “We installed pipe, storm water, sanitary and water utilities, as well as dug some retention ponds. We utilized the Doosan excavator to lift and place an oil grit separator to take the impurities out of the storm water before it goes into a stream.”

At another project, the Doosan duo worked together to redo sports fields at a local college. “We did a lot of underground work there, too,” Mike says. “The excavator was particularly helpful to backfill some of the big retaining walls, move dirt and load out trucks.

Attachments drive versatilityCommonly, the Doosan DL300 wheel loader is paired with a 4.8 cubic-yard general purpose bucket for moving dirt on jobsites or loading trucks. “It’s a support machine for other functions on the site,” Mike says. In addition to the bucket, Lounsbury has a pallet fork attachment for moving building materials and pipe.

The DX350LC excavator has a quick coupler that makes it easy for Lounsbury to switch between buckets to best match the digging conditions and required widths. “We do a lot of underground pipe work, bulk digging and truck-loading, and we shape ponds with it,” Mike says. “We have a 54-inch trenching bucket with a capacity of 2.25 cubic yards for the DX350LC. We often switch buckets when we’re trenching. For example, when we’re working in a trench box, we’ll put a narrower 36-inch bucket on.

“It’s also nice for grading and shaping banks and slopes, and cutting ponds for storm water retention. For a big

machine, it’s much more thrifty on fuel than what we’ve been used to.”

Strong dealer relationshipDecades ago, owner Stuart Lounsbury conducted business with an equipment dealer in the area, Carleton Equipment. Today, Carleton Equipment is still serving the needs of contractors in Kalamazoo, including the Lounsbury family. In the late 1970s, the dealership took on a line of compact equipment and shortly thereafter, Lounsbury purchased his first Bobcat® skid-steer loaders.

“We’ve worked with Carleton Equipment for years and years, with the owners and their sons,” Mike says. “It’s a comfort level. We feel very comfortable that if we have an issue, it will be taken care of, even it if means we need another machine until ours is fixed. That’s the biggest reason that got us interested in the Doosan equipment. And now that we’ve had a chance to put some hours on them, the machines do a good job. We expect to get at least 10,000 hours of good serviceable life out of our equipment.”

Employees at Lounsbury Excavating have quickly gotten comfortable operating in the orange Doosan wheel loader and excavator. “One of our biggest problems when we bought the Doosan machines was getting some of the operators to work in them,” Mike says. “They couldn’t get past the orange color. That’s not a problem now. We get a lot of questions from other contractors about the Doosan equipment.”

Thanks to Mike and the guys at Lounsbury Excavating, Carleton Equipment was able to rent a Doosan wheel loader to another local contractor. Even in tough times, it’s important to take a second look at another color of heavy equipment.

A CLEAR vISION

Rain. Too much or too little can be the bane of any farmer’s existence. Dean Mount of R&R Mount Farms has experienced both, but has found a way for his crawler excavators to balance out each extreme for the family operation. He recently used his two Doosan DX340LC excavators during Iowa’s historically hot and dry summer of 2012 to correct problems resulting from the devastatingly wet ones of 2007 and 2008.

Mount Farms


Preventive maintenance pays dividendsLounsbury Excavating owner Michael Lounsbury believes so strongly in preventive maintenance that he’s had contracts with Carleton Equipment for many years. The reason is simple: Maintaining equipment at the proper intervals ensures his earthmoving machines perform at peak levels, even with tens of thousands of hours.

“The dealer comes to our shop or jobsites and does all of our preventive maintenance and service work,” Mike says. “It’s about $3 an operating hour. All of our major equipment has GPS on it and we closely monitor it. The system gives us times for service, total hours, hours worked on a particular site and so forth.

“My shop foreman and I will get together once a week and we review the upcoming service schedules. The system will start alerting us at 50 hours, which is about a two-week window if we’re running fairly steady. That’s when we’ll schedule the machine for service.”

A field service truck and a trained mechanic from Carleton Equipment tend to Lounsbury’s preventive maintenance needs. “Lounsbury Excavating keeps very good track of their equipment, the number of hours, and knowing where they’re at and what they’re doing,” says howard Simmons, Carleton Equipment.

An Iowa farmer’s Doosan DX340LC excavators turn severe weather into an

opportunity for the family farm and shape a second business


Protecting the harvestPartners with his brother, Clint, and father, Rick, the Mounts farm a total of 3,000 acres in the fertile, rolling hills of southwestern Iowa. One particular section of 380 acres forms a mosaic of corn and soybean fields that hug the West Nishnabotna River. Five years ago, the swollen river jumped its banks and surged through a levy, swallowing the harvest. Another soggy year followed in 2008, and nearly every June after has brought monsoon-like rains. With no grass stand, weeds and volunteer willow trees took root and grew fast in the wet areas.

By 2012, some willows towered 25 feet high. While the dry spell — the worst drought since 1936 — had stressed most of Iowa’s crops, conditions were ideal for clearing the fields’ ditches, erecting a stronger cross dike alongside a creek bed and resloping a mile-long levy constructed by a previous landowner. The excavators, each configured with 2.5-cubic-yard, 54-inch buckets with hydraulic clamps, formed a powerful one-two punch for removing trees, clearing brush and reshaping the dike and levy walls.

By clearing the overgrowth bordering the fields, Mount plans to replant grass and control future growth to better monitor field drainage. “If you can’t see the drainage out of this bottom field, and you have a problem, it will drown out on a rainy year and you’ll lose your crop,” Mount says.

Duping a dozerR&R Mount Farms has tended fields outside of Riverton, Farragut and Shenandoah for three generations. The family knows firsthand the kind of devastation that spring storms can bring to crops and property. In the flood of 2007, Mount’s grandfather abandoned his farmhouse as it rapidly became an island. With more storms brewing, a lightning bolt sparked a fire that completely destroyed it.

His grandfather always preferred dozers to perform clearing on the farm. “Grandpa thought excavators would be a maintenance nightmare, but I wanted to try them and I’ve had a good experience. To me, it would’ve been a nightmare using a dozer for this kind of work, and it would’ve gotten stuck in some areas,” he says.

Mount says his excavator and key attachments provide more versatility than a dozer for removing thick growth. Unlike a dozer blade, the bucket provides more precise control for digging out trunks and scooping trees, stumps and root balls. The clamp secures the material, allowing him to place the roots on the outer edges of the brush piles for rinsing from the rain and better drying before burning. The clamp and front window guards combine to reduce the threat of vegetation causing cab damage. “They’ve saved my bottom window a couple of times,” Mount says.

Mount says his setup keeps his worksite cleaner and increases the excavator’s productivity. “I always want a clamp if I’m clearing trees. It speeds up the work and you can shake the dirt out of a root ball and place a tree higher. With a dozer, your pile would be three times as wide and full of dirt that won’t burn,” says Mount who likes the hydraulic attachment’s convenience. “You push a button and it’s out of your way for dirt work and digging deep holes, but it’s there at the touch of your thumb if you dig up something that needs moved,” he adds.

Mount cleared the entire levy wall by positioning the excavator on the levy’s shelf. The machine’s 22-foot digging depth allowed him to easily access vegetation in the adjoining ditch below. In the final passes, he reshaped the wall by pulling dirt to the levy’s top edge. “We moved the dirt up with the excavators and the dozer rolled it downhill so it would settle at a slope that we can eventually mow or spray,” Mount says.

Working in tandem with the dozer revealed more advantages. “The excavator’s engine is so quiet that I didn’t have to open a door or

window to hear the tracks on the dozer coming,” Mount says. Fuel efficiency has improved also, as the excavator uses approximately 8 gallons of fuel per hour compared to 12 gallons per hour in the dozer.

Operating in comfortOnce harvest is complete, the excavators will deliver the horsepower to Mount’s solo venture doing house demolition, digging basements, tiling and clearing ditches and river bottoms. Operating in a comfortable cab with controls within reach is important to Mount. “It’s easy to navigate the LCD screen and find your diagnostics. The cup holder is in a good spot and I don’t have to turn around to control the radio. There aren’t a lot of buttons to use,” Mount says.

Building a Doosan traditionAfter owning and renting competitive excavators in previous years, Mount purchased a used DX300LC in 2008 from a Doosan owner in North Carolina. He sold it to a Nebraska farmer last year and purchased two used DX340LCs. “Doosan looked like a high-quality machine when I studied them and talked to people who were knowledgeable about them. I’ve owned and rented competitive machines and I don’t see the point in spending the extra money when I have this quality,” Mount says.

The 75,000- to 80,000-pound size is best suited to Mount for securing transport permits and maneuverability in wet terrain. Those reasons are significant factors in his upcoming trade-in of the DX340LCs to purchase a DX350LC from his new Doosan dealer, Bobcat of Omaha. “I’m not going to spend the money on a used machine when I could buy a new Doosan model for the price they want for a higher-priced competitive machine. This is my opportunity to get into a new one and be set up for a very long time,” Mount says.

And, the Doosan brand has won the stamp of family approval. “Grandpa said, ‘it’s a lot nicer and I don’t have to do trees with the bulldozer.’ That’s what it’s for, and since we have a lot of bottom ground, we need one around,” Mount concludes. Maintaining a rural routine

Servicing any heavy construction equipment in a rural setting could be a challenge, and because Dean Mount is 90 minutes from his Doosan dealer, he plans ahead. “I keep a stockpile of parts just in case I have a problem,” Mount says. As a former mechanic, his excavator success can be attributed to daily diligence. “It’s a machine and you can’t expect it to take care of itself. I check it over every morning and I’m an over-greaser,” Mount admits.

After more than five years of successfully completing a variety of challenging excavation projects with the Doosan DX225LC excavator he purchased in 2007, Ewald Rothmaier describes

it as “the perfect balanced machine”

Turnkey excavation

For the past 23 years, Ewald Rothmaier has served as a full-time independent contractor for Wellington Construction, headquartered in Palmerston, Ontario. Wellington Construction specializes in heavy civil construction projects, primarily water and wastewater treatment facilities and structures. With Rothmaier’s specialty in excavating, concrete work and water and sewer installations, the success and longevity of the two-plus decade partnership is well founded.

As an experienced excavation expert and construction veteran of more than three decades, Rothmaier has witnessed several notable equipment advancements over the years, including enhancements to hydraulics, chassis/frame design, ease of operation, ergonomics and fuel efficiency — just to name a few. But according to Rothmaier, rarely does an excavator come along that combines so many important features into one efficient and reliable hydraulic excavator package.

“We just run them, and run them some more, and I haven’t had any major issues with Doosan excavators,” Rothmaier says. “I encounter conditions that will challenge any excavator and, to tell you the truth, of all the models I’ve owned previously, the DX225LC — in my opinion — is a superior machine. It’s big enough to do bulk work, but it’s small enough to get into tight places. It’s efficient, reliable and very durable.”

Service … regardless of the saleRothmaier’s relationship with Doosan began long ago when he owned another brand of excavator that was in dire need

of service. A fellow construction comrade had been doing business with CG Equipment, based in Zurich, Ontario, for several years and suggested Rothmaier get in touch with them.

“Even though it wasn’t an excavator manufacturer they represented, the good folks at CG Equipment said they could help me out,” Rothmaier says. “They have a top-notch service department and were so willing to accommodate. The excavator was similar to Doosan equipment, which CG Equipment sells. “They were able to accurately diagnose the problem and knew exactly how to fix it, since the machine was so much like Doosan equipment. It turned out to be one of the best calls I’ve ever made.”

A few months later, with the repaired excavator having surpassed the 10,000-hours-of-operation benchmark — and a solid 18-month project on the horizon — Rothmaier found himself in the market to expend his fleet. Rothmaier did his homework, including side-by-side and feature-to-feature comparisons of excavator models offered by three different manufacturers. The features and benefits of the Doosan DX225LC matched up well to other brands that Rothmaier reviewed.

“In addition to myself, I have two other guys who run the excavators; ease of operation, especially in tight, confined spaces, is critical,” Rothmaier says. “The controls on the Doosan are so much lighter than all the other equipment. For speed and operation, everything really comes together in such a nice, fluid motion with the DX225LC.”

Engineered for accuracyFocusing primarily on excavation work, Rothmaier is often on sites that involve encounters with numerous existing utilities infrastructure. Accuracy — the ability to operate a bucket or ripper as precisely as possible — is crucial. At the core of operational accuracy is operator comfort that begins with improved ergonomics designed to maximize comfort, along with excellent visibility, providing a safe and pleasant working environment.

“I especially like the lightness of touch, specifically as it relates to joystick operation,” Rothmaier says. “I was shocked at how much more effort it took for me to run the controls of other excavators. But it’s not just the accuracy and efficiency with Doosan, it’s also ergonomics. The guys are not as tired at the end of the day, so yes, there’s greater efficiency that lasts longer throughout the day because we’re not fighting the machine all the time.”

PerformanceThe performance of the DX225LC also has a direct link to productivity. Its high-pressure common-rail engine and Electronic Power Optimizing System (EPOS) of hydraulics have combined to create a highly productive hydraulic excavator, with a cost/performance ratio that makes the DX225LC even more appealing for excavator enthusiasts like Rothmaier.

The DX225LC’s diesel engine produces 155 horsepower at only 1,900 rpm, and more torque, due to its design combined with high-pressure common-rail fuel injection and four valves per cylinder. These features help optimize combustion

and minimize pollution through reduced particulate emissions. And increased torque allows for more efficient use of the hydraulic system by providing faster working cycles that enhance productivity. The EPOS system electronically links to the engine’s electronic control unit, enabling a continuous exchange of information between the engine and hydraulic system. The result is perfect synchronization, where electronic control of fuel consumption optimizes efficiency and enables fuel savings.

Ease of maintenanceThe DX225LC has been designed to simplify access to daily maintenance points, while extending short maintenance operations to longer intervals. The engine oil filter, for example, offers a high level of filtration, allowing the oil change interval to be increased to 500 hours. The oil filter is also easy to access, and is positioned to avoid contaminating the surrounding environment. Access to the cooling system is also easy, making cleaning less difficult. Arm grease points are grouped and centralized for easy access.

“Greasing takes less than 15 minutes because the various zerks are grouped

within a central location,” Rothmaier says. “Keeping an eye on all the fluids is also easy. By simplifying the maintenance points, there is a greater likelihood that operators will be more diligent about daily servicing. It’s easy to justify ignoring a service maintenance point if it’s hard to reach, or worse yet, out of sight.

“Any of the heavier maintenance chores, I have CG Equipment handle. If I know I’m having a heavy operational year, I try to get the machines in once a year to CG Equipment and they will take care of flushing radiators, draining and replenishing all fluids, and service the hydraulics and drives; all the bigger stuff. The biggest thing I can say about CG Equipment is that those guys keep me running.”

In addition to his DX225LC, Rothmaier owns and operates a Doosan DX340LC. “The DX340LC I have is a much older machine, but that thing is still really smooth,” he says. “It is just a joy to run.”

As a Doosan customer, there’s a good possibility your first exposure to the brand happened as a result of doing business with a rental branch location. Perhaps you needed an excavator equipped with a hydraulic breaker, or you specified a 2-yard wheel loader and a Doosan machine was delivered to your jobsite.

That market presence will continue to grow through a partnership between Doosan and Neff Rental, one of the largest renters of earthmoving equipment in the country. With an expansive geographic footprint, Doosan excavators, wheel loaders and other Doosan equipment are stocked in Neff Rental’s network of 68 locations throughout the United States.

According to Steve Michaels, VP of fleet management at Neff Corporation, this heavy equipment relationship is designed to provide Neff Rental’s application-driven customers with more solutions to their specific project needs.

“We have a significant investment in all three lines — Doosan Heavy, Bobcat and Portable Power — with multiple models and sizes in each group. Neff Rental and Doosan provide the right combination of specifications, attachments and accessories for our customers to customize their equipment,” Michaels says.

Strategic alliance values relationshipsMichaels is quick to point out that taking care of contractors in a competitive rental industry for a variety of earthmoving applications, as well as general and niche construction markets, means aligning with manufacturers whose products can help them successfully facilitate business.

“Customers are looking for reliability, dependability and outstanding service from their trusted rental company. They depend on us to provide a solution to their needs with a product that fills that need,” Michaels says.

The alliance between Doosan and Neff Rental demonstrates how rental companies can collaborate with selected manufacturers to deliver a valuable service to end-users.

“The rental business is really a service business,” Michaels says. “It’s taking a commodity or product, and turning it into a whole service from the time the order is taken, finding the right solution to delivery, to pickup, to billing, to maintenance,” he says, “and all those services are provided by the rental company with the manufacturer’s product. So it’s kind of a joint marketing or a joint service process.”

After years of purchasing other brands of heavy equipment for earthmoving and construction applications, the Doosan brand has gained credibility and market share among Neff Rental management. Based on past history with Bobcat® compact equipment, Michaels lists several good reasons to have confidence in meeting their customers’ demands.

Neff Rental and Doosan strategic alliance delivers customized solutions to application-driven customers

Right combination, right time

“Having a relationship with Bobcat Company absolutely propelled the product,” Michaels says. “Their past product support programs and market share all lent credibility. So, it opened the door to explore Doosan.”

Application-driven customersMichaels explains that the Doosan heavy equipment focus has allowed Neff Rental to build a very full and diverse product offering that strengthens its inventory. “It’s allowing us to streamline vendors and provide significant volume to leverage our competitiveness in the marketplace,” Michaels says.

To those product advantages, Michaels observes that Neff Rental brings a strong customer service reputation. “Given the support and training from Doosan, along with the customized programs for complete ownership, we are extremely confident that the Doosan product, along with Neff support, will prove to be a solid investment in our fleet,” Michaels says.

The partnership is built from a foundation of equipment that includes three full product lines that perform very specific applications, yet provide versatility. Michaels points to the Doosan wheel excavators as an example. “When you need a wheel excavator, it’s either a highway road job or it’s a general construction job. So, it really has two different uses,” Michaels says.

Customers often specify these excavators for certain types of road projects and other specialized excavating on jobsites where existing pavement may require the use of rubber tires. Additionally, wheel machines are advantageous for transporting a machine between jobsites — eliminating the need for trailering.

Excavators and even wheel loaders can easily be customized to a project. “In today’s world, attachments such as hydraulic breakers, grapples, clamps and buckets, and having easy access to switch these attachments with coupling systems all provide the necessary tools to satisfy a diverse application-driven customer group,” Michaels says. “It’s about tailoring the machine with accessories and attachments that allow the product to be like a Swiss Army knife,” he adds.

Beyond product, Doosan has provided Neff Rental staff with tools such as application, technical and diagnostic training to complement the product knowledge. Doosan instruction also focused on market applications and attachments. “We learned the different types of attachments that can adapt the machines to different industries,” Michaels says.

Rental trends look positiveMichaels and his colleagues at Neff Rental are bullish about the growing demand for rental transactions going forward. “In general, the secular trend that everybody talks about in the industry as the economy slowly recovers and projects are on an uptick is the shift we see from traditional ownership to rental,” he says.

As customers evaluate their purchasing and rental choices, Michaels and his colleagues remain confident that the Doosan and Neff Rental partnership represents a viable option.

“Doosan offers reliable equipment with solid factory support. Add that to Neff’s strong customer relations, service capabilities and customization to our customers, and you have a win-win,” Michaels concludes.

Neff Rental

Advantages of rentingRenting a piece of heavy earthmoving equipment can be intimidating, but Neff Rental employee Steve Michaels says it can be to the individual’s advantage to rent before purchasing a machine. he says it’s easier for some customers to write a check at the end of the month for a rental, rather than making the investment in a purchase. Renting may provide more flexibility in a customer’s monthly cash flow. Additionally, Neff Rental takes responsibility for keeping up with advances in Tier4technologiesandOSHA/ANSI training required for safety compliance (add maintaining inventory, storage, maintenance, delivery and pickup of equipment) as well as financial and tax issues. Michaels says customers can rent the equipment they need for a particular job or time period and leave all the ownership issues to Neff Rental.
