3.  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)

4.  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.

5.  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.

6.  Classification of farm machines :-

7.  Materials of construction :-
1. Ferrous materials.
i. Cast iron
ii. Steel
2. Non-ferrous materials.
i. Copper
ii. Aluminium
iii. Brass
iv. Bronze
v. Wood
vi. Rubber
vii. Plastic etc.

8. 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

9. Principle of selection of farm machines:-
 Land holding
 Soil condition
 Climatic condition
 Cropping pattern
 Repairing facilities
 Running cost
 Initial cost and resale value
 Test report
