Soil tillage energy efficiency increase

Abstract

Tillage energy efficiency increase is one of the important tasks in improving the profitability and sustainability of agricultural production. The paper proposes to increase cultivation energy efficiency due to the use of traction-drive tilling implement with active working bodies, not creating a high traction resistance and not requiring a large towing weight of aggregated tractor. The analysis of the energy efficiency of soil cultivation using traction-driven tilling implements with active working bodies has been carried out, and theoretical dependences of the coefficient of efficiency of a traction-driven machine-tractor unit has been obtained. The possibility of increasing the efficiency of the unit by reducing slipping of the tractor wheels and losses on rolling of the unit has been determined, which has been achieved by transferring part of the power through the power take-off shaft (PTO) of tractor to the drive working bodies of tilling implement, which compensate for traction resistance of the implement and create a pushing force, reducing the resistance to rolling.
