Traction as applied to agricultural tractors
Iyer, Chandrasekhar Seshadri
The problem of traction is most important from the individual farmer's point of view. For ordinary work under normal conditions a pneumatic wheel tractor can do satisfactory work as far as handling pulled equipment is concerned. However, there are times, e.g. when ploughing during the drier season of the year, when every tractor owner finds the rear wheels slip exceedlingly and has to reduce the load or wait until soil moisture conditions improve sufficiently to regain efficient traction. In certain areas farmers have been forced to buy crawler tractors at considerably greater cost than ordinary wheel tractors in order to accomplish all the jobs they wanted to get done.
