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.

A linkage for an implement is provided for connection to a vehicle. The linkage may be configured to allow extension of the linkage along its longitudinal axis, with a spring under tension that urges the linkage toward a primary operating position.

A system for removing contaminants from a surface. The system being attached to a vehicle that is movable in a first direction. The system including a first scraper for removing contaminants from a surface and a first conveyor system including a continuous track element for conveying the contaminants removed from the surface in a second direction wherein the second direction is not aligned with the first direction.

The present disclosure relates to improvements in snow removal vehicles. A vehicle is disclosed, wherein the vehicle may have a reduced turning radius, or a zero-turn radius. The present disclosure also relates to improvements in snow shovels attached to the vehicle, including disclosure directed to a snow shovel mounted to the middle of the vehicle, rather than to the vehicle's front. Further yet, the present application discloses a snow shovel which is interchangeable with a mower attachment, thereby allowing a vehicle to be used as a snow plow or as a mower.

A rotatable plow shovel apparatus for clearing a path without having to lift includes a plow blade and a shaft housing having a curved front face coupled to a back side of the plow blade. A shaft aperture extends through a top side of the shaft housing to proximal a bottom side and the back face has a plurality of adjustment apertures extending through to the shaft aperture. A handle shaft has a vertical engagement portion rotatably engaged within the shaft aperture and an angled extension portion coupled to the engagement portion. A locking pin is coupled to the engagement portion and is selectively engageable with each of the plurality of adjustment apertures of the shaft housing to lock the handle shaft in a straight position, at least one alternative left tilt position, and at least one alternative right tilt position.

A winch and plow control system is disclosed. The winch and plow control system enables automatic control of a plow attached to a vehicle in order to raise and lower the plow based upon a vehicle parameter. The vehicle parameter can be a gear input that is monitored to automatically raise and lower the plow depending upon the gear selected. Wireless and remote control of the winch is also available, as well as a back-dragging automatic plow mode and a normal automatic plow mode.

A work machine includes a motive portion, a work portion driven by the motive portion, a discharge path for discharging a work object obtained as a result of the work portion rotating, and a control portion for controlling the motive portion. The control portion includes a detection portion for detecting that the discharge path is clogged with the work object, and a work control portion for, upon the detection portion detecting that the discharge path is clogged with the work object, controlling the work portion and performing an elimination operation for eliminating the clogging with the work object in the discharge path.

Provided in this disclosure is an adjustable snowplow, including a center blade and first and second wing blades each positioned on opposite ends of the center blade. A channel is provided along a back and length of the center blade. First and second wing bars are provided, attached to respective backs of the first and second wing blades, and configured to be slidably received within the channel for reciprocal movement. In this manner, the blades are moved inwardly toward or outwardly away from the center blade, thereby adjusting an overall width of the snowplow. The channel includes a cross-sectional shape defined by a plurality of surfaces. One or more gaps are respectively formed in one or more of the plurality of surfaces, to permit snow and water that would otherwise be trapped to fall and/or flow away from the adjustable snowplow.

A system of actively introducing opposite phase vibrations to reduce or cancel vibrations caused by operating a snow plow. The invention also relates to a method of actively introducing such opposite phase vibrations.

A dozing blade assembly includes a dozing blade and a multi-piece cutter mounted to the dozing blade and including an elongate body having a first outer body piece and a second outer body piece that are mirror images of one another, and each including an inboard stem having a linear leading edge profile, and an integral outboard end bit having a curvilinear leading edge profile. The outer body pieces are structured for mounting to the dozing blade such that digging faces of the outer body pieces are oriented at a shallower angle than digging faces of the middle body piece, relative to a horizontal plane.
