A folding agricultural implement is disclosed having a frame including an inner section, a pair of intermediate sections, and a pair of end sections. The inner section and the end sections of the frame are equipped with lift wheel assemblies including a ground engaging wheel and a wheel cylinder connected to the ground engaging wheel for selectively raising and lowering the frame relative to the ground. The intermediate sections have no lift wheel assemblies. The joints between the end sections and the intermediate sections are held rigid when the implement is in the working position, but can be folded to move the implement into the transport position. When the implement is folded, the intermediate sections and end sections are first raised together relative to the inner section. After the intermediate sections and end sections reach a generally vertical position, the end sections are then folded downwardly over the inner section.
