In some implementations, a lift assembly for a moldboard of a snow wing assembly of a machine may include a lifting mechanism, coupled to an undercarriage assembly of the machine, configured to lift the moldboard of the snow wing assembly to a bench height associated with the moldboard. The lift assembly may include a hinge rotatably mounted on a bar of the lifting mechanism, wherein the bar defines a first axis, and wherein the hinge is rotatably coupled to the moldboard about a second axis. The lift assembly may include a first rotational mechanism, coupled to the lifting mechanism and the hinge, configured to rotate the hinge and the moldboard about the first axis. The lift assembly may include a second rotational mechanism, coupled to the hinge and the moldboard, configured to rotate the moldboard about the second axis.

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 snow plow having a lift actuator for a snow plow of a vehicle. The lift actuator including a lift actuator reservoir configured to accumulate compressible gas, which is operable to bias the lift actuator toward an extended position. A pneumatic valve may be operable to selectively control supply of compressible gas from a gas reservoir to the lift actuator reservoir.

A mounting bracket and method for mounting a push arm to a wing plow. The mounting bracket can include a clevis portion, a backstop, and a mounting flange. The mounting flange can have a first mounting flange hole, a second mounting flange hole, and a third mounting flange hole. The mounting bracket can be configured to be mountable to the wing plow in a first orientation using the first and second mounting flange holes and can be mountable to the plow in a second orientation, using the second and third mounting hole. The second orientation can be rotationally offset from the first orientation about at least one rotational axis.

A snow plow having a lift actuator for a snow plow of a vehicle. The lift actuator including a lift actuator reservoir configured to accumulate compressible gas, which is operable to bias the lift actuator toward an extended position. A pneumatic valve may be operable to selectively control supply of compressible gas from a gas reservoir to the lift actuator reservoir.

The device includes two opposing lateral wings forming the right and left sides of the scraping device. Each wing includes an upper section through which the wing is attached to the central support about a vertical pivot axis, and a bottom section that is pivotable with respect to the upper section about a first horizontal pivot axis. Each wing can follow the unevenness of the roadway surface and may also include parts that can pivot backwards in case of a frontal impact with an obstacle. The scraping device offers a very high degree of versatility and can clean various kinds of roadway surfaces with an unprecedented level of efficiency.

A multi-position snowplow blade, a snowplow incorporating the blade and a method of use thereof. The blade includes left and right wings that each having a trip edge pivotally engaged therewith. Each trip edge includes a lower section of a moldboard, a cutting edge, and a snow shield. A biasing assembly biases the trip edge into alignment with an upper section of the moldboard. The trip edges trip when the blade strikes an obstacle on a surface being plowed. When the trip edge trips, it pivots about a horizontal axis and relative to the associated upper section. Each snow shield pivotally engages the lower section of the associated trip edge and pivots relative thereto when the trip edge trips. The pivotal motion of the two snow shields widens a gap therebetween and helps to reduce the possibility of damage to the pivoting trip edges.

A vehicle mounted articulating snow plow apparatus is provided for clearing snow from roads and driveways. The snow plow includes a blade assembly having a center blade and an extendable wing blade coupled to each end of the center blade. The blade assembly can be raised and lowered relative to the vehicle and ground surface and can be rotated about a vertical axis. Each extendable blade is independently pivotable relative to the center blade through an arc of greater than one-hundred eighty degrees (180°) about a vertical axis. The blade assembly is extendable and retractable between at least a stowed configuration, wherein the extendable blades extend laterally inboard alongside the center blade, and a linearly extended configuration, wherein the extendable blades are outboard of the center blade. The blade assembly includes an actuation mechanism to pivot the extendable blade relative to the center blade.

The scraper blade device is provided for cleaning a roadway surface. The scraper blade device includes an upper blade portion and a bottom blade portion. The bottom blade portion has a plurality of widthwise-disposed and juxtaposed blade segments. The blade segments are provided in one or more blade segment sets where the blade segments within a same set are attached using a swivel interconnection. This scraper blade device has an improved cleaning efficiency over existing designs, thereby reducing the amounts of de-icing chemicals and increasing road safety when used for removing ice and snow from the roadway surface.

A containment plow adapted to be mounted to a vehicle such as a skid steer, a wheeled loader, or a tractor comprises a moldboard frame, a moldboard mounted to the moldboard frame, a wing pivotally connected to the moldboard frame adjacent each end of the moldboard, a moldboard cutting edge mounted to a lower edge of the moldboard and comprising a plurality of cutting edge segments, and a wing cutting edge mounted to a lower edge of each wing. Each moldboard cutting edge segment is mounted so as to have two rotational degrees of freedom movement relative to the moldboard and one translational degree of freedom movement relative to the moldboard. Each wing cutting edge is mounted so as to have two rotational degrees of freedom movement relative to the wing.
