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 tubualr 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.

摘要： A device for automatically connecting a work machine to a tractor includes a connector for interconnecting the rear ends of top link and lower links of a three-point link assembly pivoted to the body of the tractor. The connector has an upper engaging portion and lower engaging portions automatically engageable with an upper connecting portion and lower connecting portions of the work machine, respectively. The connector is further provided with an assembly for automatically coupling the input shaft of the work machine to a transmission shaft connected to the PTO shaft of the tractor. The coupling assembly includes a coiled spring supporting the rear end of the transmission shaft freely movably and axially movably for accommodating misalignment of the input shaft relative to the transmission shaft when the two shafts are to be coupled together.
