ABSTRACT:
The invention relates to an improvement in a drum rotating apparatus which comprises an input gear, a drive train for selectively drivingly rotating the input gear about its axis in a first and in a second direction, a transfer gear meshing with the input gear and driven thereby, a shaft rotatably driven by the transfer gear and having teeth thereon, an output gear meshing with the teeth on the shaft and driven thereby and a drum secured to the output gear to rotate therewith. The improvement comprises a normally engaged coupling intermediate the transfer gear and the shaft and hydraulic disengaging apparatus which serves to disengage the normally engaged coupling to allow the drum to rotate unencumbered by the input gear and the drive train.
