  • Patent number: 11591761
    Abstract: 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.

  • Patent number: 10358782
    Abstract: A plow assembly includes a mounting structure configured to mount at a vehicle, a center plow attached at the mounting structure, and a plow wing mounted at an end of the center plow via a first attachment assembly and a second attachment assembly. Each of the first and second attachment assemblies includes an elongated attachment element and a biasing element. The elongated attachment element attaches a respective rear portion of the plow wing at the center plow and engages the biasing element at the rear of the center plow. The biasing element allows for movement of the attachment element at the rear of the center plow to allow for pivotal movement of the plow wing relative to the center plow. The biasing element limits pivotal movement of the plow wing and biases the plow wing towards a neutral state, where the plow wing is generally normal to the center plow.

    Abstract: A vehicle attached rake for grooming a granular surface includes a center section and two pivotal wing sections that carry rubber trowel members having a serrated lower edge that forms a plurality of downwardly extending teeth. The tips of the teeth are located on a large diameter, upwardly facing curve to better groom upwardly curved side walls in a golf course bunker. When the rake is attached to a ZRT vehicle, the wing section on the inside of a zero radius turn is automatically lifted up off the granular surface by a flexible tether that becomes taut. Another embodiment of the rake includes a rigid plate behind a rubber trowel member with a lower portion of the trowel member folding forwardly during reverse motion of the vehicle such that the plate engages the granular surface to act as a bulldozer blade.

  • Publication number: 20090188684
    Abstract: The invention is a land clearing rake that is typically mounted on a moldboard on a conventional bulldozer. The land clearing rake pivots about a shaft that is horizontally connected to the front of the moldboard. The rake is comprised of teeth connected to each other by heavy-duty plates between each of the teeth. The teeth may be arranged in one or more sections wherein the sections can be simultaneously raised or lowered by winches mounted on the moldboard. The winches are remotely controlled from the operator's seat. Thus, the land clearing rake is capable of being quickly raised or lowered by the operator while the earth moving equipment is moving back to prepare for another forward move. The ability to quickly transition between raking and grading modes significantly improves the efficiency of land clearing operations.

  • Patent number: 6854527
    Abstract: The present invention provides for carbide edge snowplow and grader blades that are durable and fracture resistant. The carbide along the blade edge and blade bottom which contacts the surface being treated is designed to limit the degree of fracture of the carbide. Carbide inserts along the edge and/or bottom are separated from each other by a steel alloy spacer/shim along the width of the blade. The spacer/shim reduces the potential for impact damage cracks that form in a carbide insert from propagating into adjacent inserts along the width of the blade. In one embodiment, the improved blade edge comprises an edge body having a lower edge with a recess and separate slot in the bottom surface of the edge. Within the blade recess and blade slot are positioned carbide block/bar inserts separated by spacer means made from a ductile material.

    Abstract: A heated bucket system for significantly reducing the accumulation of frozen mud and ice within a bucket thereby maintaining the bucket's dirt moving capacity. The inventive device includes a bucket attachable to a pair of arms of the tractor or dozer, a pump attached to the coolant system of the tractor or dozer, an inflow tube fluidly connected to the pump, a heat tube attached to the back member of the bucket preferably in a sinusoidal pattern and fluidly connected to the inflow tube, and an outflow tube fluidly connected to the heat tube opposite of the inflow tube and fluidly connected to the coolant system of the tractor or dozer. In operation, the pump draws the heated coolant within the coolant system and pumps it through the heat tube attached to the bucket. The heat from within the coolant is exchanged with the bucket thereby maintaining the temperature of the bucket above freezing. The coolant is then returned to the coolant system through an outflow tube.
