In order to drive the tool of the pulled agricultural device (14) the tractor (10) has to be linked to a universal drive shaft, normally this was done with a chain. The new design of a link unit (20) is equipped with conical centering elements (20.2) at the part fixed to the back of the tractor (10), which fit into matching holes (40.3), positioned at the universal drive shaft (30). The universal drive shaft (30) can be adjusted in height. For joining the parts it is no longer necessary for the driver to leave and re-enter the tractor (10), the centering elements (20.2) facilitate automatic joining by reversing.
