WHEELED AND TRACKLAYING TRACTORS
Wheeled tractors occupy an important place on the farm as a source of power, and on many farms, they, together with trucks, have entirely displaced horses for farm work. An advantage of tractor power over the horse is that the tractor can be used continuously for heavy work. In addition to pulling implements like ploughs and cultivators, a wheeled tractor may be used with implements for bush clearing, ditch-filling and land-levelling. Small tractors of from 1 to 10 horsepower, fitted with single-or twin-powered petrol engines, may be used for garden and orchard work.
Wheeled tractors may be further subdivided into standard and row-crop types. Standard wheeled tractors are used for general farm work and do not have special features associated with row-crop tractors. Row-crop tractors can be used for all ordinary purposes, but in addition they are specially designed for working on root and other row crops.
The main difference between the general-purpose tractor and the tracklayer is the replacement of the four wheels by two endless tracks. These tracks transmit the power and the weight of the tractor to the soil and it is therefore able to pull or push very heavy loads. The weight of the crawler is distributed over a large track area and this keeps damage to a wet soil to a minimum, and allows a tracklayer to operate under conditions unsuitable for wheeled tractors. It is steered by controlling the speed of one track relative to the other. Hydraulic power is available for the operation of external equipment but PTO and three-point linkage are seldom fitted. Also, the work it can perform on the farm is limited and therefore tracklayers are used as farm tractors only on heavy land arable farms, where they can work in conditions unsuitable for wheeled tractors. They are used for heavy tasks such as mole drainage and earth moving.
