Stump cutters
TractorHydraulicEngine
Established by Henning Schmidt in 2002, FSI power-tech ApS
develops and manufactures stump cutters. This has been the
company’s key competency since its foundation, and it has
built up extensive know-how and expertise in the mechanical
challenges involved in cutting tree stumps.
From its factory in Ølholm near Tørring in central Jutland, the
company services all of its customers and dealers in Denmark,
and importers from a large number of countries in Europe. The
company also exports to other countries around the world,
including America, Australia and New Zealand.
FSI stump cutters are aimed at professional users, who
are primarily landscape gardeners, tree felling companies,
developers, hire companies, municipalities, housing
associations and similar companies with activities in the green
sector.
FSI ensures the high quality of all of its products by carrying out
quality assurance and testing on all of its stump cutters before
they are shipped.
We want every customer who uses an FSI stump cutter to be fully satisfied with its performance
FSI power-tech ApS
The FSI range of stump cutters consists of three groups of machines, defined by their power source.
TRIPLEX Teeth System
Every FSI stump cutter is equipped with TRIPLEX cutting teeth. The teeth are round and during operation the wearing surface covers about 120 degrees, so the teeth can be rotated three times before they have to be replaced. The teeth are secured using a single nut.
The teeth are fitted in holders made from durable cast steel. The holders are fixed on the cutter wheel so that adjustments are not necessary when replacing teeth or holders. For increased capacity, the holders are fitted in a staggered system on the disc, so that each tooth cuts its own track.
Tree stump cutting times
In collaboration with some of our customers, we have devised an overview of the time taken to cut up three different diameters of tree stumps. The figures are based on the cutting of a tree stump that is 15 cm high and which extends for 15 cm below the ground.
The times stated in the table can vary depending on the tree species, the age of the stump, the machine operator and the power of the actual tool carrier.

Towable stump cutter with petrol engine
B20 is a compact and balanced stump cutter that can be used to cut up all types of tree stumps.
The pivot joint between the stump cutter and the chassis ensures easy and smooth cutting, even under difficult conditions.
The brakes can be applied individually to each wheel, so the machine can easily access the stump even if there are shavings in
the way. The individual brakes can also be used to negotiate steps with ease.
Extra equipment
Drawbar for ball and socket coupling, for transport up to 10 km/h. Not permitted on public roads.
Hour counter with alarm for every 25 hours for lubrication and for every 100 hours for oil change. Can be retrofitted.

B22Engine
Stump cutter with 2WD and petrol engine
FSI B22 is a new stump cutter that combines the many areas of application of the B20 but which is also self-propelled, so that moving over uneven terrain is much easier, and especially when loading or unloading from a trailer. Hydraulic wheel drive, speed and forward/reverse are controlled from the handlebar. A free-running feature ensures that the machine can be moved without having to start the engine.
A swivel joint between the stump cutter and the chassis ensures an easy and smooth swing movement for the stump cutter, without the wheels having to be moved. This ensures fast and efficient stump cutting, even on inclined or uneven surfaces.

D30 TRACK: Stump cutters on tracks with diesel motor
FSI D30 TRACK is the well-known D30 stump cutter which is equipped with tracks instead of wheels. It is aimed at serious users who often work in very inaccessible terrain. The diesel engine pro-vides high performance capacity and excellent operating efficiency.
All machine operation is executed via the rotatable control panel, so the operator can stand behind the machine during operation and move towards the work site, and the control panel can be turned during stump cutting, providing a good overview of the stump during the stump cutting process. The speed of swing movement can also be controlled from the control panel.
Very safe; the safety bar on the control panel must be enabled to start the cutter head.

Stump cutters for hydraulics
Hydraulically driven stump cutter for fitting to an excavator or similar machine, where the machine itself is used to make the swing and up/down movement.
Free choice of cutting direction. The cutting direction can easily be set at 45 degree intervals, in the joint between the unit and the fitting plate for the tool attachment.
The units are supplied with an uncoated top plate, on which an optional tool attachment can be fitted. We also provide a selection of tool attachments.
The machines require a depressurised return to the tank (leak oil).
