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.

Device for connecting working implement to tractor

A load handling vehicle equipped with a load handling device comprises a pair of reinforcing frames attached to opposite sides of the vehicle body, a steering panel, a front cover covering the space under the panel from the front and a protective device covering the operator's seat and including a pair of opposite front posts connected to the frames in front of the seat. Each of the front posts comprises a lower post member extending upright from the frame and positioned in the vicinity of of the front cover, and an upper post member removably attached to the lower post member. The steering panel and the front cover are attached to the pair of lower post members and can therefore be fixed in place by a simple arrangement and yet with increased strength. When unnecessary, the protective device is removable with the panel and the cover fixed in place.

Load handling vehicle

A pair of reinforcing frames each comprising front and rear two dividable segments are attached to opposite sides of a vehicle body which comprises an engine, a clutch housing and a transmission case directly joined together into an assembly. Front and intermediate gate frames provided over the vehicle body at its front and intermediate portions astride thereof are secured to the reinforcing frames. Upper component members of the vehicle and a four-post protective frame are attached to the front and intermediate gate frames. The front and intermediate gate frames include upright members each made of a pipe of square to rectangular cross section. The members attached to the gate frames include front wheel fenders, a front cover, a bonnet, a fuel tank and a partition plate.
