ABSTRACT:
The earthworking implement has a primary frame section and a wing frame section attached to each side of the primary frame section. A folding mechanism is provided for folding each wing frame section to a transport position. The folding mechanism includes a first arm pivotally attached to the primary frame section. A hydraulic cylinder is attached to the primary frame section and to the first arm for pivoting the first arm relative to the primary frame section. A second arm is attached to the first arm and to the wing frame section. The connection between the first arm and the second arm is a lost motion connection. The first arm has a stop which engages the primary frame section and a stop which engages the wing frame section when the wing frame section is in the transport position.
