Abstract
An implement hitch system is intended to be mounted on the tongue of a towed vehicle. The hitch has a hitch body with a standard ring coupling. A ring adapter can be mounted on the hitch body to adjust the size of the ring opening to accommodate draw pins of different sizes. The adjustment includes a resilient backstop that cushions the hitch and minimizes chattering. The system also includes a clevis attachment for the hitch that bolts onto the hitch body to provide a clevis type hitch for engaging a single tractor drawbar. An additional feature is a wear plate that may be bolted onto the ring to accommodate high vertical loads.
