ABSTRACT:
A compensating hitch adapted to be coupled between a three-point draft system at the rear end of a wheeled tractor and the front end of a trailing earthworking implement which is wheel supported rearwardly of an earthworking blade thereof; the hitch including a link and lever array which functions to maintain the implement and its earthworking blade in a constant pre-set working position when the tractor traverses uneven ground, and which--with a conventional hitch--would cause the trailing implement and its blade to undesirably vary up and down from such constant pre-set working position.
