A method for controlling the drive mechanism of a utility vehicle having a power take-off shaft, where the drive mechanism including an engine, a transmission, a power take-off shaft clutch and a controller, operates the drive mechanism in a careful and economical manner. The method of controlling the engine includes the step of issuing an instruction for engaging the power take-off shaft clutch at a low rotational speed of the engine so that the power take-off shaft clutch is engaged in a controlled manner. If the rotational speed of the engine is above a threshold, the rotational speed is automatically reduced before the engaging the power take-off shaft clutch. After fully engaging the power take-off shaft clutch, the rotational speed of the engine is automatically increased until reaching of the rotational speed of the engine required for the nominal rotational speed of the power take-off shaft. When disengaging the power take-off shaft clutch, the controller automatically reduces the rotational speed of the engine.
