摘要： A tractor has a three-point link assembly comprising a top link and opposed lower links which are connected together by a connecting assembly at their ends toward a working implement. The connecting assembly comprises an upper connector and lower connectors removably in engagement with corresponding connectable portions of the implement. The PTO shaft of the tractor is connected to an input shaft of the implement by an extendable transmission shaft having a pair of tractor joint and implement joint at its opposite ends. The connecting assembly has a clutch for separably operatively connecting an externally splined portion of the implement input shaft to an internally splined portion of the implement joint. The clutch comprises a guide fixed to the connecting assembly and extending substantially longitudinally of the tractor, a tubular case provided in the guide movably axially thereof and an operating assembly for the case. The implement joint is inserted in the case.
