Abstract
Mechanism operating through a mechanical advantage for rolling over a two-way gang plow comprises a pair of hydraulic cylinders acting through respective short links connected pivotally at one of their ends to their associated cylinders and at their opposite ends pivotally to spaced pivots on a bell crank lever secured to the roll-over shaft of the plow, the spacing between the bell crank lever pivots being less than the spacing between the link pivots. Annular rings surround the roll-over shaft for abutment by the links during operation of the mechanism, providing each link with a fulcrum point which is arranged to augment the output of the associated hydraulic cylinder during the initial portion of its extension.
Claims4
A roll-over mechanism for a two-way gang plow having right and left hand plow bottoms mounted on a supporting frame rotatable about a horizontal axis carried by a main frame, the roll-over mechanism comprising:
- a. a pair of extensible, reciprocative actuation means for rotating the supporting frame,
- b. mounting means on the main frame for securing one end of each of the pair of actuation means in fixed position relative to the main frame,
- c. a lever pivotally interconnecting the opposite end of each of the pair of actuation means and the supporting frame, and
- d. fulcrum means coaxial with said horizontal axis arranged for engagement by said levers intermediate the ends thereof for providing leverage in initiating rotation of the supporting frame from the operative positions of the plow bottoms.
