Abstract
A mounting frame for attaching a bucket or other implement to a three-point tractor hitch. The frame is formed by two beams connected by a plate and by front and back cross braces. Each beam is made from a single piece of steel plate bent to provide a side plate, an inclined triangular top plate and a tapered rib. The side plates are pinned to the two draft links of the hitch and the ribs are reinforced and pinned to the upper hitch arm. The beams taper from front to back and terminate in spaced apart arms which carry the bucket. A trunnion mounted hydraulic cylinder for manipulating the bucket is mounted on the back cross brace and connected at its rod end to the bucket.
