Tractor drawn fully reversible plough - has pressure compensation vessels connected to turning ram chambers

摘要

The fully-reversible plough comprises a three-point mounting, a turning ram, and a frame to which the plough shares are fixed. Pressure-compensation vessels are connected to the ram pressure chambers, to reduce shock-loads. Alternatively there can be a single vessel connected to the rod end, or the head end, of the ram, or connected to each alternately by a control valve.
