Abstract
A rotary cutter includes a hitch comprising upper and lower arm sections which define a parallel linkage extending between the deck of the rotary cutter and a ball clevis forming a forward end of the hitch. The ball clevis includes identical upper and lower halves which include block-like rear portions that are clamped together so that a ball is releasably retained between ring-like front portions of the clevis. Leveling of the deck is accomplished by a pair of adjustable leveling mechanism respectively coupled between rear parts of the separate arm sections and the deck. Provision is made for mounting a jack stand to one side of the clevis and for storing the jack stand on the deck.
