Abstract
A hitch assembly for a tractor is disclosed, which includes a rotatable carriage support that is carried on a fixed trunnion for providing oscillation of the hitch frame about horizontal first axis. The rotatably carriage support also pivotally mounts a hitch carriage about a second axis to provide the hitch assembly with the ability to articulate as well. Camming apparatus is also provided to progressively restrict the oscillation of the hitch frame as it is being raised and stop surfaces restrict articulation when the hitch frame is in its raised position. The articulation and oscillation ability of the hitch provides improved ease of steering and control of the tractor and improved ground contact of a ground-contacting implement on the hitch frame. A power-take-off shaft extends through said center of the fixed trunnion supporting the hitch mounting to permit simultaneous connection of the implement with the hitch and the power-take-off shaft for transmitting rotary power to the implement.
