Abstract
An automatic disengaging method for a master clutch dependent power take-off (PTO) arranged in a vehicle for preventing undesired movement or actions of the implements associated with the PTO and undesired wear of a clutch collar (release bearing). The PTO is driven by an engine via a master clutch between a crankshaft of the engine and an input shaft in a gearbox. The gear box further comprises an output shaft which is powered by the input shaft, optionally via an intermediate shaft. A power take-off is connected to the input shaft or, optionally, to the intermediate shaft. The system further includes a control unit connected to the master clutch and the gear box. When the control unit registers that the master clutch is disengaged, a gear is engaged in the gearbox and certain conditions are fulfilled (e.g. a parking brake has been actuated for a certain time), the control unit performs the operations of putting the gearbox in a neutral position, disable the power take-off, if the power take-off is enabled, and engage the master clutch.
