Transport lock for forwardly folding agricultural implements

摘要

An agricultural planter is provided with wing members that fold forwardly from a laterally extending operating position to a compact transport position. The wing members are supported on wheel assemblies when in both the operating and transport positions. A transport lock mechanism is operable to secure the forwardly folded wing assemblies in the transport position against the draw bar. A latch tower having vertically oriented latch retainer bars permit the wing members to move vertically relative to the draw bar without disengaging the transport lock to allow the wing member wheel assemblies to follow ground undulations in the transport position. A wheel lock is also provided to convert the wheel assemblies between a forwardly fixed position used when the wing members are in the operating position and a castering position that enables the wing members to move into the transport position. A wing latch actuator interconnects the transport lock mechanism and the wheel lock mechanism to effect operation thereof in a coordinated manner.
