The disclosed Power Shift Mechanism is adapted to laterally shift an earth working implement, such as a vertical plow, relative to a tractor or the like. In the disclosed embodiment, the plow is mounted on a slide bracket and the bracket is slideably mounted on a support frame. The shift mechanism includes a fluid operated piston-cylinder connected between the frame and a pivot link pivotally connected to the slide bracket. The pivot link may be rotated by the piston-cylinder to either of two positions and locked in place by releasable connectors. The pistoncylinder will then rotatably shift the pivot link or laterally shift the bracket and the earth working implement. The shift mechanism thus increases the effective stroke of the pistoncylinder and reduces the power requirements of the shift mechanism. |
