Abstract: A hitch may be configured to laterally offset the longitudinal axis of a towed implement with respect to the longitudinal axis of a towing vehicle so as to shift the towed implement to either of a left side or a right side of the towing vehicle. The hitch may provide added reach to either of a left side or a right side of a towing vehicle and provide a significantly reduced turning radius. In some embodiments, the advantages of including a variable offset hitch may be achieved without adding excessive length between a towing vehicle and pulled implement.
