ABSTRACT:
A coupling device for connecting the power take off means of an agricultural tractor to a driven shaft of an implement includes an upper guide member 20 connected between the tractor and the implement from which the drive shaft 16 is resiliently supported by the springs 42. The guide member 20 is telescopic and is lockable, when the tractor is coupled to the implement, by means of a lever arm 40 to which the springs 42 are connected. In the coupled condition the lever arm is retracted thereby releasing the drive shaft 16 from the resilient bias of the springs 42 and thereby releasing the drive shaft bearings from any spring loading during operation.
