To the issue about the tractional passability of high-clearance completely-driven four-wheeled universal-row cotton crop tractor

Abstract The results of researches implemented in the sphere of improving the agrotechnical passability of 4-wheeled universal-row cotton crop tractor are specified in the article. Replacing these two types of wheeled tractors with one high-clearance 4-wheeled tractor significantly reduces the range of fleet and increases the annual load of universal-row crop tractor of 1.4 class, and finally, increases the efficiency of their applying. The weight distribution of perspective four-wheeled universal-row crop tractor onto four wheels and fully drive reduces the negative impact on soil in comparison with three-wheeled tractor and allows to aggregate machines having enlargedrow-spacings. Evaluation of P indicator (the passability margin) is shown. It characterizes the passability through more problematic matters due to traction-coupling properties presowing soil processing proceedings, which showed the possibility of applying the tractor as well at all remaining operations, provided for by the technological map and being performed by the units on the base of this tractor.
