Abstract
Flat circular discs in powered operation mode create driving forces. These forces enable to decrease the wheel slippage of the energy saturated tractor of tillage unit and to reduce the specific energy consumption. The objective of this study was to develop a technique that enables to determine the disc-mover optimal parameters for maximum efficiency criterion. The earlier developed mathematical model of soil-disc interaction was used for this purpose. Soil properties are characterized by means of two empirical constants in the model. The relative depth and the kinematic parameter determine the disc operation mode. It was shown that the disc-mover can operate with high efficiency, if the disc operates at the optimal values of the parameters. The disc-mover efficiency can achieve the value about fifty percents. The experimental results confirmed the adequacy of the technique. The proposed technique can be modified to optimize the parameters of other powered rotary tools of tillage machines and units.
