Abstract
A quick hitch coupling for use with a powered machine and a drawn machine. The coupling comprises a receiving unit attached to forward end of an implement in a substantially stationary position and an engaging unit attached to the powered machine which may be lowered and raised. The receiving unit comprises a cavity defined between a substantially vertically disposed rear plate laterally spaced from a substantially vertically disposed front plate. The engaging unit attaches to the powered machine so as to be movable between an elevated operative engaged position and a lowered disengaged position. The engaging unit includes a substantially vertical plate of a size and shape to fit within, and substantially fill, the cavity of the receiving unit. The engaging unit may thereby be positioned in its lowered position beneath the cavity of the receiving unit and raised to its operative position into coupled engagement with the receiving unit.
