Abstract

A milling attachment for a work machine includes a frame including first and second frame side walls and a frame top. The frame top includes a movable front cover portion. A first adjustable side plate has a first ground engaging portion for engaging the ground surface. A first actuator is operably associated with the first adjustable side plate for raising and lowering the first adjustable side plate relative to the first frame side wall. A first actuator extension connects the first actuator to the movable front cover portion, the first actuator extension being configured such that the movable front cover portion is moved relative to the frame when the first adjustable side plate is raised or lowered relative to the frame.
