There is provided a differential motion conveyor comprising a trough and a conveyor drive. The conveyor drive comprises a clutch/brake assembly which is selectively activated for moving the trough at a first speed in a first direction and selectively deactivated when moving the trough at a second speed in an opposite direction. There is further provided a method of conveying material comprising sensing a position of a trough, activating a clutch/brake assembly when the trough is at a first position for moving the trough at a first speed in a first direction, and deactivating a clutch/brake assembly when the trough is at a second position for moving the trough at a second faster speed in a second opposite direction to the first direction.
