  • Patent number: 7033105
    Abstract: A road paving equipment tire track remover having a pair of blade assemblies, each including a semi-flexible blade with a lower edge and an upper edge. The upper edge is affixed to and shaped by a V-shaped frame so as to create a concave front side of the blade. The blade assembly is attached to the surface of a road paving vehicle near and behind the rear wheels of the vehicle in such a manner that the lower edge of the blade is in contact with the road surface. The blade assembly also includes a parallel scissors assembly to allow for vertical movement of the blade while in use, and a weight box to selectively adjust the pressure exerted by the blade on the road surface.

  • Patent number: 6691435
    Abstract: A snow plow system for use with a skid steer loader includes a V-plow blade that is repositionable by a hydraulic actuator operated by pressurized hydraulic fluid supplied to the actuator from the auxiliary hydraulic output of the skid steer loader. A normally open valve diverts hydraulic fluid away from the actuator whenever the plow blade is not being repositioned, enabling the auxiliary hydraulic system to be maintained actuated. The valve is operated to a closed condition by a wireless remote control receiver which receives coded radio frequency signals transmitted by a wireless, portable, battery-powered transmitter locatable within or outside of a cab of the vehicle, or by a voice-actuated control. A mounting panel of the snow plow system includes an anti-slip surface, providing footing for an operator upon entering or exiting the cab of the vehicle.

  • Patent number: 6108946
    Abstract: A V-blade plow having a pair of adjustable plow blades. Each plow blade has an inner end pivoted on a central pivot assembly. A plowed material catcher member is mounted below the central pivot assembly to prevent a trail of snow from passing through any space between the inner ends of the blades at any position of blade adjustment. The plowed material catcher member includes an arcuate ramp portion which projects forwardly of the central pivot assembly and directs snow to the blades respectively. The catcher member is made from a material selected from rubber, plastic or metal.

  • 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: 5392864
    Abstract: Blade assemblies for use with compacting vehicles are normally designed to push the material in front of the blade and to control the height of the material passing thereunder for compaction by the compacting vehicle. With the blade raised to allow trash and/or soil to pass thereunder, the trash and/or soil passing thereunder may cause detrimental wear to the components under the compacting vehicle between the compacting mechanisms. In the subject arrangement, a blade assembly is provided and includes a blade pivotally connected to a frame. The blade has a working edge that permits, during use, level spreading of trash and/or soil when the blade is in a first operative position. When the blade assembly is raised and the blade is pivoted forwardly with respect to the frame, a first portion of the working edge controls the volume of trash and/or soil allowed to pass under the working edge between respective compacting mechanisms of a compacting vehicle.

  • Patent number: 4731942
    Abstract: A dozer blade of the present invention includes two curved blade sections that are joined at respective inner ends thereof. The blade sections are joined to form a unitary blade exhibiting a concave surface for scraping and removal of snow and the like. The blade sections converge forwardly at the top toward their central juncture such that a top portion of the central juncture is generally positioned forwardly of a bottom portion thereof. Additionally, the top portion of the central juncture is generally positioned lower than outer ends of respective top portions of the blade sections, presenting a winged profile from the front. A divider is positioned along the central juncture from a bottom scraping portion of the blade sections to the top. The divider serves to distribute material being dozed generally equally to either side.

  • Patent number: 4625988
    Abstract: The present invention provides a quick hitch for connecting a prime mover to an implement to be used with the prime mover. The prime mover has a male assembly which can be quickly and easily hitched and unhitched to the female assembly of the implement. The male and female assemblies matingly receive one another and a locking mechanism on the female assembly maintains the two assemblies in a locked relationship. The prime mover is driven towards said implement until said male and female assemblies matingly engage one another, thereby engaging the locking mechanism and hitching the implement to the prime mover. To unhitch the male and female assemblies, the locking mechanism is moved to the unlocked position and the prime mover is driven away from the implement.

  • Patent number: 4597202
    Abstract: A V-shaped under frame with a transverse rear member connected at its ends to forwardly converging side members has spaced uprights connectable to a truck. Pivots connected in aligned relation on each side member connect to ribs on the convex rear side of right and left moldboards. The inner edges of the moldboards are closely adjacent along their upper portions, but diverge along their lower portions. Backing springs on the side members bias the tops of the moldboards forwardly. A low V-shaped plow point is connected by a strut to the under frame and located within the space left by the diverging lower portions of the moldboards. Roadway engaging shoes are connected to the under frame adjacent each of its three corners.
