Abstract: A hitch extension apparatus for attaching an implement with a pto driven drive shaft having front and rear universal joints to a tractor drawbar. The apparatus comprises a first member adapted for attachment to the tractor drawbar by insertion of a drawbar pin through the drawbar such that the first member is fixed with respect to the drawbar. An extension member is pivotally attached to the first member about a horizontal pitch axis oriented perpendicular to the travel direction, and about a horizontal roll axis oriented parallel to the operating travel direction. The extension member defines a pivotal attachment location rearward of the draw pin hole adapted for pivotal attachment of the implement about a vertical yaw axis located equidistant from the front and rear universal joints when the drive shaft is connected to the tractor power take off. The pitch axis can be located forward of the yaw axis, and forward of the draw pin hole in order to reduce bending forces on the drawbar.

Abstract: An offset tow arm apparatus for towing an implement supported by at least one wheel having a rotational axis perpendicular to the operating travel direction comprises a tow arm having an inner end and an outer end. A pivot arm has a rear end pivotally attached to an inner portion of the tow arm and a front end adapted for pivotal attachment to a towing vehicle hitch. A lock is operative to lock the pivot arm in a fixed position with respect to the tow arm. An outer castor wheel is pivotally attached to the apparatus to support the outer end of the lateral, and an inner castor wheel is pivotally attached to support the inner end of the tow arm. An implement hitch is attached to an outer portion of the tow arm between the outer and inner castor wheels and is adapted for attachment of an implement to be towed behind the tow arm. The apparatus is adapted to prevent lateral movement of the implement with respect to the tow arm.
