Draft power and energetic balance of tractors
University of Belgrade, Faculty of Agriculture
Keywords: tractor; draft balance; energetic balance
Abstract
The study focuses on the basic parameters composing the tractor-machinery aggregate taking into consideration draft power and energetic balance of the 4x4S tractor: tractor mass, engine power, draft power, speed, specific mass productivity. The main objective of composing an optimal tractor-machinery aggregate may be sought in harmonizing draft-energetic potential of the tractor with draft-energetic needs of implements. The tractor is expected to function in the exploitation range of draft power achieving a comparatively high degree of useful tractor effect. Coefficients for the estimation and computation of draft power characteristics of a tractor in stubble, draft power of the tractor in stubble in an optimal exploitation range depending on tractor mass, plough width scope depending on furrow depth, specific soil resistance and draft power of a tractor on chernozem and black marsh soil type and the effect of specific mass of the tractor on draft power and speed are given.
