  • Patent number: 9163371
    Abstract: A snow removal system utilizes a towing frame having a towing device such as a winch or winch crank. A towing line extends in a straight line path directly from the towing device to a uniquely shaped snow shovel having dual, concave shaped blades. Actuation of the towing device pulls the snow shovel towards the towing frame, causing snow on the ground surface to accumulate on and slide off and to the side of the blades.

  • 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.

  • Publication number: 20040237352
    Abstract: A scraper for moving friable material. The scraper includes a frame adapted for attachment to a vehicle and an articulated blade. The blade has left and right portions mounted on the frame for pivoting about a substantially horizontal axis transverse to the articulated blade. Each of the left and right portions of the articulated blade is adapted for pivotal movement about the axis between a substantially horizontal lowered position and a raised position, and each portion is independently positionable in at least one position between the lowered position and the raised position. The articulated blade is positionable for engagement with the friable material as the vehicle travels over the friable material for moving a part of the friable material to shape the friable material in accordance with a predetermined design.

  • Publication number: 20040040184
    Abstract: The present invention is a lightweight, one-person-operating plow designed to remove new-fallen or otherwise soft snow or slush. It is inexpensive to manufacture, ship, market, and purchase. Its two units can be assembled and connected to any kind of vehicle in less than one minute. Disconnection and disassembly can be effected in like time. It can remove virtually all of the snow from the path being cleared very quickly; for example, a 100-foot driveway can be cleared in about fifteen seconds, and a 50-foot driveway in half that time. Very little physical effort by the user is required, and no damage is caused to the surface being plowed.

  • Patent number: 5974703
    Abstract: A drag-along snow apparatus for use upon a snow covered ground surface. The snow plow apparatus includes a first substantially planar and elongate extending member and a second substantially planar and elongate extending member which are interconnected along a common vertical edge and which form, in combination, a substantially V-shaped configuration. First and second planar and horizontally arrayed cross members extend between the first and second elongate extending members and brace the connection between the elongate extending members. A length of rope is secured to the plow apparatus via a looped end which extends successively through a first rope support aperture located at a forward end of said elongate extending member and a second rope support aperture located at a forward end of said second elongate extending member. The rope permits a user to drag the plow apparatus along a snow covered ground surface.

  • Patent number: 5007187
    Abstract: A snow plow member is attached to selected ones of the shanks of a cultivator frame by inserting the leading edges of the sweep at the lower end of the shank into slots formed on the rear surface of the snow plow member. A leading edge of the snow plow member follows the C-shaped curvature of the shank. The shank is clamped to the underside of the snow plow member. With such snow plow members attached to selected ones of the cultivator shanks, the snow plow members can be used to form furrows in the snow which acts to trap additional snow and to prevent the snow from being stripped from the field. The resultant increased accumulations of snow provide additional moisture retention for the field.

  • Patent number: 4802293
    Abstract: An earth-moving attachment for use with a vehicle includes a pair of earth-moving blade assemblies mounted on a main beam. The earth-moving blade assemblies are adapted to be independently movable in several planes with respect to each other and with respect to the main beam so that a plurality of earth-working operations can be performed, and the attachment is amenable for use in conjunction with a wide variety of terrains. The blade assemblies are mounted and designed to efficiently transfer forces with the main beam.
