Claim Text:
1. A detachable pick mechanism, comprising: a drive transmission having a drive shaft gear operatively connected to a pick axle gear, the drive shaft gear slidably engageable onto a cantilevered drive shaft extending from a housing; a pick axle having a pick wheel mounted at each end, the pick axle operatively connected to the pick axle gear for rotating the pick wheels; and a transmission housing having: and, a latch assembly mounted on one of the first side and the side plate for rotatably engaging a groove in the cantilevered drive shaft to axially position the pick mechanism on the drive shaft, the latch assembly comprising: wherein, during mounting of the pick mechanism onto the drive shaft using an axial pushing force applied to the handle, the free end of the drive shaft initially separates the catches and deflects the pair of opposed resilient latch arms with the catches subsequently engaging the groove on the drive shaft with the pair of opposed resilient latch arms returning to a less deflected position thereby rotatably latching the pick mechanism to the drive shaft, and, during dismounting of the pick mechanism from the drive shaft using an axial pulling force applied to the handle, the catches slide up the respective inner ramps of the at least two opposed rails and disengage from the groove in the drive shaft allowing the pick mechanism to axially slide off of the free end of drive shaft.
