Abstract
In a combine harvester, a supplementary header drive is provided for driving the header components in reverse as needed, for example, for clearing blockages of crop material in a platform auger or in the feederhouse conveyor. The drive is powered by a hydraulic motor and selectively connected to the header drive system by a hydraulically actuated clutch. Clutch and motor are connected in parallel to the hydraulic power source and components are designed and sized so that the hydraulically actuated clutch engages before the hydraulic motor begins to rotate.
