A drive assembly including:
- a drive shaft having a longitudinal axis and that is rotatably driven about said axis;
- a clutch surrounding the shaft and through which the clutch extends so as to provide a shaft portion beyond the clutch, the clutch having a first clutch part associated with the shaft so as to be rotated therewith, and a second clutch part selectively movable into engagement with the first clutch part so as to be drivingly associated therewith, and a drive member engaged with the second clutch part so as to be drivingly associated therewith so that the drive member and shaft portion can be simultaneously driven when the first and second clutch parts are engaged.
