Power rating ranges from 1.3 to 150 HP
To select appropriate size of farm tractors, the following must be considered.
Common types Include:

The maintenance of an accurate record of costs is an indispensable part of the machinery manager’s job.
Such records assist decision making processes that are the core of good machinery management.
Ultimate goal of a machinery manager is to maximize enterprise profits, get a higher output from his machines at minimum cost.
Time of replacement of a machine is one of the most important decision making activity of the machinery manager.
Machinery costs are divided into two categories:
Depreciation: The amount by which the value of a machine decreases with the passage of time whether used or not.
The value declines due to the following:
Methods of calculating Depreciation
Service life of a machine (Physical Life): Needed to estimate depreciation. It terminates instantly due to irreplaceable part or irreparable part.
Economic Life of a machine: The length of time from purchase to that point where it is more economical to replace with a second machine than to continue with the first.
Accounting life of a machine: Predicted life of a machine in hours of use based on the surveyed use of existing machines and on design life used by the manufacturer.
Renting and Leasing
Interest, tax, Insurance and Shelter
Approximate Annual Cost: Estimation for future cost of use for farm machines is important to machinery managers. Good estimates help in costs of production, size selection and replacement decisions can be made.
The actual costs are determined at the end of each year from cost records
An efficient method of matching equipment to the true needs of agriculture will benefit both the manufacturer and the farmer.
The selection of an equipment is a complex problem at farm level.
To select field machinery, the following factors must be taken into consideration.
AC = FC%/100 X P + 8.25/SWE X [R&M +L + O+F+T]
(Where the symbols have their usual meaning)
If all the variables are expressed in terms of per metre of machine wheel basis with the exception of T, then
AC = f(w)
Graph relating annual cost and machine width.
Cost of power is significant in many operations.
Some implements are self propelled but most are powered by tractors.
Tractor capacity is designated by horsepower.
The annual cost for a farm power unit can be expected to consist of
Where K = timeliness factor
Y = Potential crop yield (t/ha)
A = Area (acres)
V = Value of crop (N)
The following can also guide decision on purchase of used equipment.
Involves thorough knowledge of:
