摘要： The top link of a three-point link assembly on a tractor is connected to the two lower links thereof by a connecting assembly at the link ends toward a working implement. The connecting assembly has upper and lower connectors separably engageable with corresponding upper and lower connectable portions of the implement. An extendable transmission shaft having a pair of joints at its respective ends is interposed between the PTO shaft of the tractor and an input shaft of the implement. The connecting assembly has a clutch for operatively connecting an internally splined portion of the implement-side joint to an externally splined portion of the input shaft. The clutch has guides fixed to the connecting assembly and extending longitudinally of the tractor, a tubular case supported by slide members on the guides and movable axially thereof and an operating assembly for the case. The case has the implement-side joint inserted therein. The slide members each have a spring for holding the case translatably and swingably upward or downward relative to the guides.
