Abstract
A forwardly foldable agricultural planter includes a hitch shiftable as wing sectons are moved between transport and operational configurations. Rigid link tow bars pivot about centrally positioned pivots permitting the hitch to be horizontally shifted between transport and operational positions to thereby realize positive drawn implement control in both configurations. A telescoping drawbar provides further implement support and control and either manual or automatic latching mechanisms can be provided to secure the folded wing sections in position.
