Abstract
A snow plow having a wing that is rotatably coupled to a side of a primary plow, and configured to rotate about a first axis substantially parallel to the side of the primary plow. A portion of the wing is operable to rotate about a second axis that is non-parallel to the first axis, where the portion is operable to rotate upward about the second axis relative to the ground in response to the wing encountering an obstruction. A snow plow having a receiver coupled to a surface of the primary plow and an actuator coupled to the receiver. The receiver allows the snow plow to move proximally and distally with respect to a vehicle.
Claims20
A linkage for a snow plow comprising:
- a cylinder including a first cylinder end and a second cylinder end;
- a piston movable within the cylinder between the first cylinder end and the second cylinder end;
- a rod coupled to the piston, the rod including a rod end movable relative to the second cylinder end;
- and
- a compressible gas in contact with the piston and operable to bias the piston and the rod such that the linkage biases a plow portion of the snow plow to a bias position, wherein the cylinder is operable to receive hydraulic fluid to move the piston and the rod such that the plow portion of the snow plow moves away from the bias position.
A method of operating a linkage for a snow plow, the method comprising:
- providing a cylinder and a piston within the cylinder that is movable between a first cylinder end and a second cylinder end, wherein a plow portion of the snow plow is coupled to the piston via a rod;
- expanding compressible gas against the piston to move the piston from the first cylinder end to the second cylinder end such that the plow portion is moved via movement of the piston and the rod;
- and
- supplying hydraulic fluid into the cylinder to move the piston from the second cylinder end to the first cylinder end such that the plow portion is moved via movement of the piston and the rod.
