ABSTRACT:
A rearwardly folding wing-back implement has a V-shaped frame configuration comprising two wing sections having the apex of the V-shape located at a pivot point where the wing sections are joined. A towing linkage minimizes the pulling forces being applied to the wing sections other than those pulling forces applied in the direction of movement of the implement. The implement may be pivoted rearwardly about the pivot point when transport is desired.
