Drive System For An Infeed Conveyor Of A Harvester

A drive system for an infeed conveyor (22) of a harvester (10), particularly according to one of the preceding claims, comprising:

• a hydraulic pump (66), the flow rate of which can be varied by means of a first actuator (76),
• a hydraulic motor (68) that is connected to the hydraulic pump (66) via a hydraulic fluid conduit and functionally connected to the infeed conveyor (22), and
• a control (70) that is connected to the first actuator (76) and a foreign object detector (108) and can be operated in such a way that it causes the first actuator (76) to adjust the flow rate of the hydraulic pump (66) to zero when a foreign object is detected by the foreign object detector (108),
• characterized by the fact that the hydraulic motor (68) has a displacement that can be varied by means of a second actuator (88) that is connected to the control (70), and
• by the fact that the control (70) can be operated in such a way that it causes the second actuator (88) to increase the displacement of the hydraulic motor (68), preferably to the maximum value, when a foreign object is detected by the foreign object detector (108).
