摘要：
A lift support system for a wheel assembly that provides variable support for the wing frame section of a tillage implement above the soil. The lift support system includes a vertically oriented tube slidably connected to the wing frame section for movement along a vertical axis. A wheel axle assembly is pivotally connected to the lower end of the tube and provides a support for the axle assembly. Wheels are journaled on the axle assemblies. A locking assembly selectively locks the wheel assembly in place when the tube is in a position for field transport and field operation with the locking mechanism being disengageable when the wing section is in a transport position to permit castoring of the wheel assemblies.
