Abstract:
1. A three-point front hitch mountable to a front portion of a frame of an agricultural tractor, said three-point hitch comprising: a main backing member securable to said front portion; an upper hitch-point anchor bracket formed from a first pair of parallel, spaced-apart plates, which are secured to the main backing member, said upper hitch-point anchor bracket providing an upper hitch attachment point for the securing of an upper implement attachment link; an A-frame assembly pivotally coupled to the main backing member, said A-frame assembly having a pair of arms which distally diverge, each arm having an implement pivot bushing at its distal end, the implement pivot bushing of each arm being coaxial with the implement pivot bushing of the other arm, said arms having a generally horizontal position when a three-attachment-point implement is secured to the hitch; a hydraulic cylinder coupled between the upper hitch-point bracket and the A-frame assembly, said hydraulic cylinder operable to rotate the A-frame assembly through an arc, thereby raising or lowering the implement pivot bushing thereof; and a hitch receiver affixed to said A-frame assembly, said hitch receiver projecting downwardly when said A-frame assembly is in a generally horizontal position; wherein at least one coupling end of said hydraulic cylinder is pinned to at least one oblong aperture, which provides an amount of play for the A-frame assembly so that an implement mounted to the hitch has a degree of float for accommodating a certain amount of non-planarity of soil over which the mounted implement travels.
