The invention relates to a drawbar support assembly. There is a need for a drawbar support assembly which can adapt to different types of drawbars. An adaptable drawbar support assembly includes a generally U-shaped front support member for coupling to and supporting the front end of the drawbar. A front spacer member mounts in the front support member above or below the front end of the drawbar. A generally U-shaped rear support member couples to and supports the drawbar. A rear spacer member mounts in the rear support member below the drawbar. The rear spacer member is removable from the rear support member when the front spacer member is mounted above the front end of the drawbar. A ball coupler is attached to the rear end of the drawbar when the front spacer member is mounted above the front end of the drawbar. A clevis coupler is attached to the rear end of the drawbar when the front spacer member is mounted below the front end of the drawbar.

Adaptable drawbar support assembly

A drawbar pin adapter which can allow a smaller drawbar pin to be used with a larger drawbar. A drawbar pin adapter is provided for a tractor drawbar having a lower strap, an upper strap and a drawbar pin bore which extends through the upper and lower straps and which receives a drawbar pin. The adapter includes a cylindrical bushing mountable in the drawbar pin bore in the lower strap and a hollow housing which is mountable over the lower strap. The housing includes a lower plate, an upper plate and left and right side plates. The upper plate has an upper bore formed therein, and the lower plate has a lower bore formed therein. The upper and lower bores have a diameter which is smaller than an outer diameter of the bushing so that the upper and lower plates hold the bushing within the drawbar pin bore in the lower strap. The bushing and the upper and lower bores receive the drawbar pin when it is inserted through the upper and lower straps. A retainer retains the housing to the drawbar when the drawbar pin is removed from the drawbar pin bore. The retainer includes a cable coupled to the housing and looped around a portion of the drawbar.

A method of making an investment or lost foam casting assembly of a first part movable with respect to a second part includes making first and second separate wax or foam patterns of portions of the first part. Then, a third wax or foam pattern of the second part is made. Next, ceramic core pieces are made. At least one of the core pieces is mounted on the first pattern to form a subassembly. The subassembly is combined with the third pattern so that the core pieces maintain a separation between the third pattern and the first pattern. The first and second patterns are bonded together to trap the subassembly and to form a complete casting assembly.

Method of making a casting assembly

A hitch assembly is mounted on a frame of an agricultural tractor. The hitch assembly includes a pair of draft links pivotally mounted on the frame, a drawbar support fixed to the frame between the draft links, and a pair of sway blocks fixed to opposite sides of the frame. Each sway block has an upper end fixed to a side of the frame and extends generally downwardly to a lower free end. The lower free end of each sway block is positioned below a plane defined by a bottom surface of the drawbar support. Each sway block is preferably tapered from a wider front side to a narrower rear side to form an inner surface which faces inwardly and rearwardly. A wedge plate is mounted beneath the drawbar support. The plate extends generally laterally from a left end surface to a right end surface, and each end surface is slanted in order to matingly engage the inner surface of a corresponding one of the sway blocks. The wedge plate is longer than the drawbar support, and projects laterally out from the left and right ends of the drawbar support. As a result, the wedge plate end surfaces engage the inner surfaces of the corresponding inner sway blocks and supports them against side forces applied by the draft links.
