Patent

CA 2289312

An agricultural planter is provided with forwardly folding wing members that allow conversion of the planter from a laterally extending operating position to a compact transport position. To increase stability for the planter, the draw bar telescopes as the wing members are folded forwardly into the transport position. Brace members interconnect a forward portion of the draw bar and the wing members. As the wing members fold forwardly, the brace members are arranged to cause a rearward portion of the draw bar to extend rearwardly from the forward portion and effect the telescopic action in the draw bar. A draw bar hitch lock linkage is provided to keep the draw bar compacted when the wing members are in the operating position. A hitch lock actuator is tied into the hydraulic system for the movement of the wing members into the transport position to permit the telescopic action of the draw bar in concert with the forward folding of the wing members.
