Abstract
A device for engaging and disengaging a power shaft and driven elements of a forage wagon or similar tractor drawn implement. A split sheave clutch having a driving face connected to the power shaft and a driven face connected to the driven elements is engaged by tightening a V-belt between the faces. The belt tightening mechanism includes an idler pulley shiftable to and from a belt tightening position and a latching mechanism releasably securing the pulley in the belt tightening position. A latch control member connected to a safety bar extending across the front of the wagon releases the latching mechanism to disengage all the driven elements when the operator either pushes or pulls the safety bar. The driven elements can be re-engaged with the power shaft by shifting the pulley to the belt tightening position without need for the operator to first return to the tractor to stop the power shaft.
