Abstract
A traction coupling between a tractor and an agricultural implement, capable of being easily shiftable between a towing position and a position in which the implement is mounted on the three-point-lift of the tractor. The coupling includes a traverse which is mountable between the opposed ends of the lower lift arms of the tractor lift and is provided with a rearwardly projecting towing member, which is length adjustable to alternatively permit the implement to be mounted direct behind the tractor in lift engagement with the said traverse.
Claims15
A traction coupling for coupling a tractor of the tractor lift fitted type with an implement such as a cultivator propelled by the tractor, comprising a traverse constructed for mounting between opposed ends of lift arms of the tractor lift and a towing member projecting rearwardly from the traverse and constructed for connecting with the implement, characterized in that the towing member is pivotally connected to the traverse and is adjustable in length in such a manner that the coupling, by adjustment of the length of the towing member and without disconnection of the towing member or an end thereof, is shiftable between a towing position, in which the towing member is extended rearwardly relative to the traverse and an articulated coupling is obtained, and a lift mounted position, in which the towing member is contracted relative to the traverse and a relatively rigid coupling is achieved so that a front end of the implement, in use, is located adjacent the traverse in traction and lifting engagement therewith.
