The implement has a main frame supported at the rear by ground-engaging transport wheels and at the front by ground-engaging gauge wheels. A hitch is pivotally connected to the front end of the main frame so that the hitch and frame can flex relative to one another when the towing tractor experiences different terrain than the main frame. A self-leveling mechanism is normally disengaged when the implement is in its field operating position so that the hitch is free to float relative to the frame during terrain changes. However, when engaged, the self-leveling mechanism operates to maintain the main frame level as the transport wheels are lowered to raise the main frame into its transport position. A latch, remotely actuatable from the tractor seat, determines whether the implement is in its self-leveling mode or floating hitch mode.
