Abstract: A tractor-implement arrangement for establishing a frictional connection between the power take-off shaft of a tractor and a Cardan shaft for the drive of a movable implement by an automatic coupling of members respectivaly connected to the power take-off shaft and the Cardan shaft. The implement is connected to the tractor by means of automatically interengaging coupling members or elements while one and/or the other coupling element of the power take-off or Cardan shaft is axially displaceable while being spring urged. The Cardan shaft is supported by suitable holding means and is liftable by a lifting device. The Cardan shaft is moved first by guiding the same along an inclined plane toward the take-off shaft and is frictionally coupled thereto whereupon the implement is mounted on the tractor by interengagement of additional coupling members.
