Patent ID: 7331901

Claim:
A drive arrangement of an agricultural machine comprising a combustion engine connected to both a control unit configured with a default value of engine RPM, and a power take-off (PTO) transmission having selectable transmission steps which is further connected to a power take-off having a PTO output that is associated with a sensor for determining the RPM of the PTO output, where the control unit is coupled with a first operator input device to influence the RPM of the combustion engine and a second operator input device that is adjustable to set a maximum RPM of the PTO output, the control unit being configured to regulate the RPM of the combustion engine during operation based on the input of the first operator input device and to limit the RPM of the combustion engine based on the input of the second operator input device, the limit of the RPM of the combustion engine being limited to the maximum RPM value entered on the second operator input device based on a measured value of the sensor.
