ABSTRACT:
The farm implement drawbar is provided with a transverse frame which is pivotally mounted at the rear of the drawbar for movement between a working position and a transport position. The ground engaging rollers are mounted on the frame while separate transport wheels are also fixed to the frame. When the hydraulic ram is actuated to pivot the frame between the work position and the transport position the transport wheels and the earth working wheels move with the frame as a unit.
