Abstract
A grass cutting attachment for use particularly with compact tractors has a mounting frame, two cutting units lying behind the tractor front wheels and respective support arms which extend from a forward part of the frame rearwardly over the tractor front wheels to support the cutting units. The support arms are pivotal about inclined axes so that the cutting units may be lifted and simultaneously brought sideways into the tractor to reduce overall width. The cutting units are mounted for rocking movement relative to the support arms about fore and aft axis, these axis becoming inclined in the lifted position so that each unit is tilted forwardly and upwardly to improve operator access.
