The present invention relates to a snow plow assembly for a vehicle comprising a snow plow frame that is attachable to an associated vehicle. The snow plow blade is attachable to the snow plow frame and has a snow plow surface for use in plowing associated snow. An end gate is pivotally attached to at least one distal end of the snow plow blade. The end gate has a snow plow surface for use in plowing associated snow. A hydraulically operable adjustment mechanism is operatively attached to the snow plow blade and the end gate. The adjustment mechanism releasably secures the end gate in at least three different positions relative to the snow plow blade. A pivotally connected stop assembly means is operably attached to the snow plow blade and the end gate by a hydraulically operable adjustment mechanism.

An improved material pusher or containment plow employing a floating vehicle-coupling system, a wear shoe, as well as a plurality of removable scraping edge sections.

For a V-plow having a pair of blades hinged together along inboard ends of the blades at a hinge, a gauge on a lower end of the hinge having a spacer, the spacer having a thickness in a direction generally transverse to a longitudinal axis of the V-plow corresponding to a desired minimum spacing between inboard ends of a pair of cutting edge plates to be installed on the blades, a method of installing the cutting edge plates on the blades is provided. The method comprises positioning one of the cutting edge plates along a lower edge of one of the blades so that the inboard end of the one cutting edge plate abuts one side of the spacer, securing the one cutting edge plate to the one blade, positioning the other cutting edge plate along a lower edge of the other blade so that the inboard end of the other cutting edge plate abuts the other side of the spacer, and securing the other cutting edge plate to the other blade.

The present disclosure provides a plow blade edge device for mounting to a moldboard of a plow comprising at least one adapter blade including a bottom edge having selectively carbide insert(s) along at least a portion of the bottom edge. The disclosure further provides for a method of brazing the carbide insert(s) in a cavity along at least a portion of the bottom edge. The device further includes at least one wear block selectively reversible to present the adapter blade at a first angle or a second angle. The at least one wear block can include a bottom edge having a carbide insert along at least a portion of the bottom edge.

A low cost plow lift and down pressure system comprising a lift frame having a lift end and a mount end for securing to a plow vehicle. A lever beam articulates with a lift end of the lift frame. The system further comprises a; lift tension line, down pressure tension line, hydraulic pump, hydraulic cylinder, push frame, down pressure arm, and plow. A push frame extends between a plow and a lift frame. A lift tension line extends between a plow receiver near the plow and a lift receiver on the lever beam. A down pressure tension line extends between a first down pressure receiver on the lever beam to a second down pressure receiver located on a down pressure arm that is coupled to the push frame. Active extension and retraction of a first hydraulic cylinder causes consequent raising of the plow and plow down pressure.

A tilt sensing and signaling device for a containment plow.

The compact pulling apparatus includes a watertight elongated housing extending along a longitudinal axis and a track disposed around the housing along its longitudinal axis. The track enables the apparatus to move when rotatably driven around the housing. Depending on the implementation, the apparatus can include a generator/motor to selectively produce electricity which can power external equipment and rotatably drive the track, and/or a fuel-power engine. The apparatus further includes a power train assembly by which the rotating output power is transmitted from inside to outside the housing by the power train assembly using at least one rotatable shaft section sealingly extending across a corresponding one of the walls of the housing.

An apparatus for locating, inspecting, or placing marks on a roadway. The apparatus includes a GPS-based machine vision locator for sampling discrete geographical location data of a pre-existing roadway mark evident on the roadway. A computer may determine a continuous smooth geographical location function fitted to the sampled geographical location data. A marker is responsive to the GPS-based locator and geographical location function for replicating automatically the pre-existing roadway mark onto the roadway. The apparatus is typically part of a moving vehicle. A related method is disclosed for locating, inspecting, and placing marks on a resurfaced roadway. A similar apparatus can be used to guide a vehicle having a snow plow along a snow-covered roadway, or a paving machine along an unpaved roadway surface. The apparatus provides for accurate determination of roadway mark locations, roadway mark inspection apparatus and roadway markers using Bayesian model-based filtered enhanced GPS geographical location data.
