Abstract:

The existing methodology of determination of optimal energy saturation of tractor does not take into account the features of mountainous tillage. In the work, the capability of unit is related with power on the hook of tractor, angle of slope inclination and characteristics of lateral movement of unit at transversal operation on slope. In accordance with maximal capability criteria of unit or maximal efficiency criteria is determined the optimal value of energy saturation as relation between engine power to the mass of tractor in the given range of operating speeds.
