Milling drum with internal drive motor

摘要

An axially rotatable groundworking implement mountable to a host vehicle. The groundworking implement is powered by two hydraulic motors between the side ends of the groundworking implement. The shaft of each motor includes a bore which functions as either the hydraulic fluid input port or output port for that motor. Each hydraulic motor shaft is nonrotatably affixed to a groundworking implement protective cover. The groundworking implement can be removed from its supporting mechanism without detaching the motor from the work implement.
