Abstract
A hydraulic system for a detachable implement such as draper platform for a combine utilizes a platform-mounted pump supplied with return oil from the existing reel drive motor. The system utilizes the existing combine hydraulic connection for the reel drive to supply oil to the draper belt drive motors. Oil from the combine powers the reel drive motor and then flows into a manifold block (mixing chamber) before entering the inlet of the draper belt drive pump. This pump is sized to provide sufficient oil flow to power the draper belt drive motors, arranged in series. Return oil from the belt drive motors is routed back to the manifold block where it can mix with incoming oil from the reel drive pump before returning to the combine reservoir or being recirculated to the belt drive motors. The hydraulic system avoids the need to equip the platform with a complete hydraulic system and avoids the need to modify the existing hydraulic system of the combine.
