Abstract
A drive arrangement for an agricultural machine with an internal combustion engine used to drive removable agricultural implements. The engine is connected to a control unit and to a power take-off (PTO), which drives the removable agricultural implements, by means of a power take-off transmission with selectable transmission steps. The engine is further coupled to a sensor that captures the RPM of the PTO outlet, to a first operator input device that influences the RPM of the combustion engine and to a second operator input device that inputs a maximum RPM of the PTO output. The control unit controls the RPM of the combustion engine to the input value of the first operator input device while limiting the RPM of the engine based on the RPM at the PTO outlet, which cannot exceed the input value of the second operator input device.
