This document provides information about tractors, including their uses, types, costs, economic life, and maintenance requirements. It defines a tractor as a vehicle designed to deliver high tractive effort at slow speeds for hauling trailers or machinery. The document outlines different types of tractors and factors to consider when selecting one, such as the size, intended job, terrain, and future uses. It provides price ranges for some Sonalika tractor models and notes the typical economic life of a tractor is 10-15 years. Finally, it lists important maintenance practices like inspecting safety devices, brakes, and stressed parts regularly.

5. Tractors and Related Equipment
 Tractors have many uses as construction
equipment. While their primary purpose may be to
pull or push loads, they are also used as mounts
for many types of accessories, such as front-end
shovels, bulldozers and others. There are types
and sizes to fit almost any job for which they are
usable.

6. Types of Tractors:
In selecting a tractor several factors should be
considered such as the following:
1. The size required for a given job.
2. The kind of job for which it will be used.
3. The type of footing over which it will operate.
4. The firmness of the haul road.
5. The smoothness of the haul road.
6. The slope of the haul road.
7. The length of the haul road.
8. Finally, the type of work it will do after this job is
completed.

9. Cost of Tractors

 Sonalika DI 745 III TractorRs.7.51 Lakh
 Sonalika DI 60 MM Super TractorRs.5 Lakh

11. Economic Life of Tractor
 The economic life of a machine is the number of
years over which costs are to be estimated. ... A
good rule of thumb is to use an economic life of
10 to 12 years for most farm machines and a 15-
year life for tractors, unless you know you will
trade sooner.

12. Maintenance
1. Tractors should be maintained according to the
recommendations of the manufacturer as laid down for
ordinary work conditions. It is recommended that all
machines be repaired and reconditioned during the off
season and sufficiently in advance of use.
2. Steering mechanisms, control mechanisms, warning
devices, lights and governors should be maintained in a
safe operating condition.
3. Right and left brakes should be adjusted so that braking
is equal on the two rear wheels.
4. All stressed parts of frame members, including safety
cabs or frames, should be carefully and regularly
inspected and maintained in a safe operating condition.
5. Guards and safety devices should be inspected
regularly.
6. Seats, audible signals, spark arrestors, and silencers
and other noise reduction devices should be inspected
regularly
