A plow system includes a mounting structure configured to mount at a vehicle, with a center plow pivotally attached at the mounting structure. The center plow is pivoted in a first direction responsive to actuation of a first actuator and is pivoted in a second direction responsive to actuation of a second actuator. A first plow wing is pivotally mounted at a first end of the center plow and a second plow wing is pivotally mounted at a second end of the center plow. Responsive to pivoting of the center plow to a first fully pivoted orientation toward a first side of the vehicle, the first and second plow wings both pivot to a forward orientation. Responsive to pivoting of the center plow to a second fully pivoted orientation toward a second side of the vehicle, the first and second plow wings both pivot to a rearward orientation.

This present invention relates to an improved snowplow system for commercial snowplow trucks. The snowplow system includes a snowplow blade, a mechanical side shield that raises or lowers into a position generally perpendicular or orthogonal to the snowplow blade. The side shield prevents selective and intermittent snow displacement from one side of the plow blade for an effective snowplowing process that avoids snow discharge in undesirable areas. The side shield features a retraction and activation control inside the snowplow truck cab, along with three adjustable speed settings to accommodate snow conditions and vehicle speed. A hydraulic mechanism and a rotating actuator are present for rotation of the snowplow blade and the side shield.

A snowplow blade has a rolling body, a snow removal cutting edge connected to a lower portion of the rolling body, a motorized assembly for attaching the rolling body to a means for moving the snowplow blade forward; a plurality of nozzles delivering a de-icing liquid for the residual snow left on the road surface by the cutting edge; and a circuit for feeding and controlling the de-icing liquid sent to the nozzles; the feeding and control circuit having a mechanically operated monostable valve and a feeler, which is designed to cooperate, in use, with the road surface or with a mobile member of the motorized attachment assembly in order to close the monostable valve when the height of the cutting edge from the road surface exceeds a predefined threshold value.

A down pressure plow system with a float function is disclosed for use in a vehicle. The plow system includes a plow frame assembly and a plow blade carried by the plow blade assembly. An actuator is configured to move the plow blade up and down. A down pressure linkage is coupled to the plow frame assembly. The down pressure linkage applies a downward force to the plow blade upon actuating the actuator to move the plow blade and simultaneously allows the plow blade to move upward upon an upward force being applied to the plow blade.

A skid wheel system that has a shoe with two wheels attached. The first wheel is positioned adjacent to one side of the shoe and the second wheel is positioned adjacent to the other. The skid shoe has at least one connection opening to connect the skid shoe to a snow removal device. The circumferential edges of the wheels extend past at least the bottom, and protrude beyond the sides of the skid shoe, so as to protect the bottom, front and rear of the housing of the snow removal device from contact with concrete seams, and other uneven surfaces. The wheels can also, extend past the top of the shoe, so the system can be removed, rotated, and reattached in the event the bottom of the shoe wears to the point of no longer protecting the bottom of the snow removal device.

The invention relates to a clearing strip (1) for the clearing blade of a snowplow, having an attachment neck (2) onto which an elongated rubber body (4) is vulcanized, which body has a freely bendable wear section (6) that projects downward, having a wear surface (7) and a wear height (8). It is the goal of the invention to resolve the conflict of goals between gentle, rapid, and thorough clearing in areas of use having extremely sensitive ground coverings, in particular airfields, in the best possible manner. For this purpose, the invention proposes that plastic slide bodies (5) are inserted into the wear section (6), distributed over it.

A blade assembly may include a blade and a wing. The blade may be configured to be pivotably attached to a machine. The wing may be pivotably attached to an end of the blade to adjust a width of the blade assembly. The wing may be movable relative to the blade over a range of motion that is greater than 180 degrees.

A plow blade has a moldboard shaped with a concave front contact surface that faces a forward direction and has a convex rear frame surface that faces an opposite rearward direction, wherein the rear frame surface has a supporting frame with one or more supporting frame members that extend in the rearward direction. A first indicating lamp is coupled to the plow blade and is energizable to emit light of a first color in the rearward direction, wherein the energized first indicating lamp is concealed from visibility from the forward direction. A second indicating lamp is coupled to the plow blade, energizable to emit light of a second color, and visible from the forward direction.

A snow plow-blower operates as a snow plow, snow blower/thrower or as a snow plow-blower combination. The snow plow-blower includes a plow head blade and at least one blower door. The cavity contains a snow moving means, single, dual, or multi staged, for moving snow, ice and other materials out through at least one discharge chute and/or at least one opening. The blower door is adapted to move to a partially open configuration to expose the cavity, and from the partially open configuration to a partially closed configuration to thereby decrease snow, ice and other material ingress into the snow blower unit. Preferably, at least one retractable and extendable wing is located on the plow head blade to advantageously provide varying closed and open extended position configurations or positions for the removal of snow, ice or other material and debris.

A cutting edge attachment including a cover retaining plate and a cutting edge is provided. The cover retaining plate includes through-hole bushings extending outward for receiving a corresponding number of fasteners to mount the cutting edge to an adapter plate. The cutting edge includes elongated openings for receiving the bushings, a top edge having notches for receiving springs, and a bottom edge. The cover retaining plate is configured to secure the cutting edge to the adapter plate using fasteners inserted through the bushings, the elongated openings of the cutting edge, and holes defined in the adapter plate. The springs are disposed between the notches and a top edge extension of the cover retaining plate and configured to compress in the vertical direction. The cutting edge is configured to move vertically as the bushings travel within the elongated openings when an upward force is applied to the cutting edge.
