ABSTRACT:
A stepless drive for vehicles, such as agricultural tractors, which must have a wide range of very low speeds is provided by a hydraulic drive which is selectively engageable in place of the conventional gearbox drive. The hydraulic drive shaft is selectively engageable with the drive shaft of the motor vehicle via a gear shift mechanism in an auxiliary gearbox. An electronic interlock assures that the hydraulic drive is engaged with the drive shaft only when the conventional gearbox drive is disengaged from the drive line, and vice versa.
