ABSTRACT:
A forage wagon or the like having components driven by a power take-off shaft and including apparatus for selectively disengaging the power take-off shaft and the driven parts. The disengaging apparatus includes a safety clutch having a circular drive clutch plate supported on a drive shaft of a power take-off shaft for rotation with the drive shaft and a driven circular clutch plate freely rotatably supported on the drive shaft. The driven clutch plate functions to drive the various driven parts of the forage wagon. In the normal operating condition, a drive pin, aligned parallel to the axis of the drive shaft, is received through bores in both the drive plate and the driven plate such that the driven plate rotates with the drive plate. The drive pin supports a cam pin which is received in slideable engagement against a camming surface and engageable with a trip lever which can cause sliding movement of the cam pin relative to the camming surface and consequent axial movement of the drive pin out of engagement with the driven plate thereby disengaging the drive plate and the driven plate. A further aspect of the invention includes an actuating assembly providing a secondary safety means responsive to actuation of the safety clutch and for causing disengagement of a second clutch controlling operation of the forage wagon driven beaters and main conveyor.
