Theoretical investigation of a rear-mounted linkage for wide-span tractors

Abstract

The work is devoted to the investigation of the peculiarities of aggregation of wide-span tractors (vehicles) with agricultural machines and implements. As a result of the conducted studies, it has been established that, from the point of view of the control impact (the turning angle of the driven wheels) and the disturbing impact (the turning angle of the mounted implement in a horizontal plane) exerted by the wide-span tractor, the most desirable is such a variant of configuration of the mounted device in which the instantaneous centre of rotation, formed by the convergence rays of its lower links, is in the centre of the mass of the tractor. When using wide-span tractors(vehicles) with mounted implements of the high 4N and 4 categories in accordance with the ISO 730: 2009, one should consider a possibility to configure them both for a three-point and a two-point scheme.
