A drive system of a utility vehicle comprises a drive motor, a load drive train to drive a load, a propulsion drive train to driver propulsion means of the utility vehicle, and a control unit, which is connected to an actuator for setting the transmission ratio of the propulsion drive train, can be provided with a signal concerning the power consumption of the load, and generates the correction value sent to the actuator on the basis of the signal, so that the propulsion speed of the utility vehicle remains at least approximately constant even if there is a change of the power consumption of the load and/or a pitching motion of the utility vehicle caused by a change of the power consumption of the load is minimized.
