PROSPECTS FOR STEEL WHEEL TRACTOR DEVELOPMENT WITH HYDRAULICDRIVE

The article discusses a new scheme for increasing the lateral wheel tractor stability intended for agrotechnical measures, transport and other works complex on mountain and foothill slopes. The proposed scheme of a steeply sloping wheel tractor provides for hydrostatic transmission use instead of a mechanical one, which eliminates the need to install swinging final drives, simplifies the design, and reduces the tractor weight and cost. To ensure the vertical position of the tractor body on a slope, the front and rear drive wheels have an individual hydraulic drive and are mounted on parallelogram suspensions.
