Abstract
A drive arrangement for the drive of an agricultural implement is provided that includes a drive engine that can be brought into a drive connection over a separable power take-off shaft clutch with a power take-off shaft output. A drive line of the operating implement is connected with the power take-off shaft output, with an overload clutch, and a control arrangement. The control arrangement is connected to a sensor arranged for the detection of the torque at the power take-off shaft output and, in normal operation, permits an actuator to disengage the power take-off shaft clutch as soon as the torque detected by the sensor reaches or exceeds a first threshold value, that corresponds to a torque that is smaller than the cut-off torque of the overload clutch. Immediately following, the control arrangement orders the actuator to engage the power take-off shaft clutch and when the power take-off shaft clutch is disengaged permits a torque at the power take-off shaft output that is greater than the cut-off torque of the overload clutch.
