  • Patent number: 8776406
    Abstract: A reversible wing plow including a hitch, a moldboard and a moldboard shifting mechanism. The hitch is coupleable to the rear of a prime mover. The moldboard is operably coupled to the hitch proximate an inboard end and rotatable about a first horizontal axis that extends outwardly from the hitch generally parallel to a direction of forward movement of the prime mover. The moldboard shifting mechanism includes first and second linear actuators, both of which are coupled to the hitch at one end and coupled to opposing sides of a rotation crank plate on the other end. The crank plate is further operably coupled to the moldboard, whereby the moldboard is rotatably shiftable to the driver or passenger side of the prime mover, or to a vertically oriented transport position.

  • Patent number: 6662478
    Abstract: In one embodiment, the present invention includes a grading blade disposed between a pair of holders. An adjusting mechanism is rigidly attached to the grading blade. A threaded connector is used to adjust the vertical position of the grading blade. Each holder is attached to a rear portion of a utility bucket, e.g., by welding. A plurality of gussets are attached to one of the holders and to the utility bucket, thereby providing further attachment and supported to the present grading assembly. The grading blade may be rotated, thereby using each of a pair of grading edges as desired. Moreover, the grading blade may be detached and repaired or replaced. When installed on a utility bucket, the present grading assembly allows precision grading to be conducted when driving in both forward and rearward directions.

  • Patent number: 6470604
    Abstract: A snowplow attachment for mounting to the front end of a vehicle that includes both a push blade operable during forward movement of vehicle and a pull blade operable during reverse movement of the vehicle. The pull blade drops down in front of the push blade such that pushed snow can then be pulled back. The snowplow can get up close to permanent structures such as buildings and remove snow therefrom. During the push mode, the pull blade is raised to avoid interference with pushed snow. The snowplow can include side plates located on the ends of the blades for containing the snow and prevent snow from escaping out the sides, thereby increasing the volume of snow moved by the plow during one sweep. According to one embodiment, the snowplow includes a push blade assembly that is adapted to mount directly on the vehicle and a movable pull blade carried by the push blade assembly.

  • Patent number: 6314666
    Abstract: The material moving blade has a moldboard assembly with a lower moldboard portion and an upper moldboard portion. A hinge connects the upper moldboard portion to the lower moldboard portion for pivotal movement about a horizontal axis. An upper cutting bar with an upper bar working edge is clamped to a top edge of the upper moldboard portion. A lower cutting bar with a lower bar working edge is clamped to a bottom edge of the lower moldboard portion. An actuator pivots the upper moldboard portion about the horizontal axis in one direction to a position in which the upper cutting bar is above the lower moldboard portion and in another direction to a position in which the upper bar working edge is below the lower bar working edge and the upper moldboard material contact surface faces rearward.
