Evaluation of the energy supply for a tractor with different engine characteristics

Key words:

Evaluation of tractors, existing at present, on their energy supply is shown not to consider the tractor type, engine characteristics, operating conditions, and therefore can not be accepted as a technology criterion. The tractor energy supply is necessary to define, using the calculated engine power as a dividend. The engine forcing on the moment of the skidding tractor TB-1M of 70 kW is equal on the energy supply, defined by the calculated average power, to the increase of the service power by 23% (from 70 to 86 kW).
