  • Publication number: 20150107136
    Abstract: A snow plow includes a control unit for raising an auger housing to a predetermined upper limit angle when travel device is reversing, and an acceleration sensor for detecting acceleration produced in the auger housing. The control unit determines an angle of inclination of the auger housing on the basis of the acceleration. When the travel device starts moving forward after having temporarily moved in reverse, the control unit sets an intermediate lowering target angle of inclination, which is in the lowering path of the auger housing from the upper limit angle to a pre-reversing angle of inclination, in accordance with the forward acceleration; lowers the auger housing at a given lowering speed from the upper limit angle to the intermediate lowering target angle of inclination; and lowers the auger housing at a gradually decreasing lowering speed from the intermediate lowering target angle of inclination to the pre-reversing angle of inclination.

  • Patent number: 5909960
    Abstract: A universal mounting assembly for a light duty snow plow using a lower triangular frame, an upper triangular frame and a pair of spaced-apart rearwardly directed tubular members for attaching the lower triangular frame to a vehicle. The mounting assembly can be secured to a vehicle using a quick release mechanism regardless of the vehicles ground clearance. Additionally, the plow can be used in any one of a plurality of predetermined positions with the bottom edge of the snow plow blade remaining substantially flat against the surface to be plowed. An electric winch that is supplied power from the battery of the vehicle to which the snow plow is mounted, is used to raise and lower the snow plow.

  • Patent number: 5485690
    Abstract: A lightweight snowplow configured of a number of small components, each easily lifted, moved, assembled, dis-assembled and stored by an average individual. The snowplow is especially suitable for use with small vehicles such as small trucks, utility vehicles and cars. The snowplow features novel alternate arrangements for operational lifting, stopping and lowering of the snowplow and a quick-hitch/release mechanism for easy plow attachment purposes. Finally, the mounting structure to which the plow is attached and detached is designed so as to be able to fit most small utility vehicles with two fore and aft frame chassis members and a frame mounted metal bumper without need for welding or special custom fit-up.

  • Patent number: 5435082
    Abstract: An apparatus, for stabilizing a plowing implement mounted on a motor vehicle, comprising a rigid stabilizer member having first and second opposed ends. One end of the stabilizer member supports an attachment device for attaching the stabilizer member to a plowing frame secured to a motor vehicle. The attachment device allows pivoting motion of the stabilizer member relative to the plowing frame. The second end of the stabilizer member has an abutment surface for abutting against a pivotable portion of the plowing implement when the plowing implement is raised into travel position. The stabilizer member is pivotable into an inoperative position where complete freedom of movement of the plow is achieved and an operative position by a control mechanism. When the stabilizer member is in its operative position, the abutment surface abuts against a pivotable portion of the plowing implement to minimize undesired bouncing of the plowing implement while the vehicle is traveling on a roadway.

  • Patent number: 5346018
    Abstract: An inventive three-point hitch assembly that attaches to the front end of a truck or pickup and supports at three points a plurality of implements or tools. It has a belt-driven power take-off for rotary tools that is controlled by an electric clutch and driven by a pulley attached below the truck engine pulley. A hydraulic lift cylinder raises and lowers the hitch and implement or tool, which by the hitch parallelogram form maintains the implements in a vertical orientation. The lift cylinder hydraulic pressure is supplied by connections to the truck power steering system via electrically controlled solenoid valves.

  • Patent number: 5205058
    Abstract: A roadbed maintenance device includes a first frame adapted for attachment to the front end of a vehicle, and a second frame to which a moldboard is joined. The first frame and the second frame are pivotably joined by a parallelogram linkage, so that the second frame can be pivoted between a lowered position in which the lower edge of the moldboard touches the roadway, and a raised position in which the lower edge of the moldboard does not touch the roadway. The pivoting movement is preferably accomplished by biasing the second frame toward the raised position, and applying a force to accomplish pivoting toward the lowered position. The pivoting force is provided by a gas-actuated cylinder linked to the second frame, using a compressed gas source on the vehicle. The moldboard is desirably made of molded rubber.

  • Patent number: 5191729
    Abstract: Safety apparatus for use in a moldboard assembly having a plurality of horizontally aligned trip blade units pivotally supported in the bottom of the moldboard frame so that the units move independently between a downwardly extended operative position and a rearwardly extended, fully tripped position. A biasing mechanism urges each unit into the operative position with a predetermined amount of force. A control mechanism further regulates the biasing force exerted on each unit so that the biasing force first increases as the unit moves out of the operative position and then decreases as the unit continues to move into the fully tripped position. The force exerted on each unit when in the fully tripped position is considerably less than that used to hold the unit in the operative position thereby preventing the assembly from lifting as it moves over an obstacle.
