Farm mechanization:- Introduction:- India is a vast country covering about 3.29mh

Geographical area. About 166mh is cultivable land, and net area

sown is about 142mh. The farm holdings in India are classified as:-

a) Marginal farmers (<1 ha)

b) Small farmers (1-2 ha)

c) Semi-medium farmers (2-4 ha)

d) Medium farmers (4-10 ha)

e) Large farmers (>10 ha)

India is producing yearly more than 2.5 lakh tractors, 10,000 power tillers, 4.5 lakh sprayers & dusters, 9.5 lakh pumping sets and 2000 combine Harvesters.

At present Agriculture machinery population in India is estimated at about 150 million which includes about 3 million tractor and other self propelled machines.

Scope of farm mechanization:-

To improve irrigation facilities.

Introduction of H.Y.V. seeds.

Introduction of dose of fertilizers and pesticides for different types of crops.

Introduction of new crops.

Multi cropping system & intensive farming.

Classification of farm machines :-

Materials of construction :-1. Ferrous materials.i. Cast iron

ii. Steel

2. Non-ferrous materials.iii. Copper

iv. Aluminium

vi. Bronze

vii. Wood

viii.Rubber

ix. Plastic etc.

Heat treatments:-

There are several methods of heat treatment such as:-

1. Hardening

2. Annealing

3. Tempering

4. Case hardening

i. Carburising

ii. Nitriding

iii. Carbonitriding

iv. Cyaniding

v. Induction hardening

vi. Flame hardening
