  • Patent number: 7805866
    Abstract: A float mechanism for movably attaching an implement to a vehicle has a mounting frame that connects onto the vehicle and a fixed frame that affixes to the implement. A pivot bracket pivotally attaches to one of the frames and is slidably connected to the other to accommodate a limited degree of translational motion. The pivot bracket can slidably connect to the frame by a pair of guides in combination with a pair of sleeves. Rotational motion between the fixed frame and the mounting frame can be limited by slots in one of the frames that are slidably engaged by a stabilizing element on the other frame. When the stabilizing element is a horizontal bar, it can engage a pair of vertical slots. To optionally eliminate the free motion between the frames, movable blocks can be employed to limit the motion of each stabilizing element in its slot.

  • Patent number: 7360327
    Abstract: A pusher/bucket has back plate with wings pivotably mounted at either end, and a drop blade pivotably mounted thereto. The drop blade can be secured in a raised position where it is superimposed over the back plate; when in the raised position, the wings can be positioned relative to the back plate to provide a wing plow. The wings can be folded parallel to the back plate, with the raised drop blade residing therebetween. When the wings are normal to the back plate, the drop blade can be secured in a lowered, horizontal position; in this position, the drop blade acts as the bottom of a loading bucket, the sides being formed by the wings and the back plate. A float mechanism allows the pusher/bucket to push material across uneven terrain, and is preferably disabled when the pusher/bucket is configured as a bucket for loading and dumping material.

  • Patent number: 6068065
    Abstract: An attachment assembly is provided for quickly and conveniently mounting a roller onto and immediately ahead of an elongate blade of a road grader or other vehicle which manipulates and moves the blade over a ground surface. The portable roller has an elongate body with a continuous cylindrical outer surface for contacting and working the ground surface, and an axle element about which the roller rotates and which protrudes from each opposed end of the roller body. The attachment assembly is removably receivable on the blade and rotatably holds the roller by the protruding axle element. The location and orientation of the roller relative to the ground surface is controlled by manipulating the blade. The assembly provides an alternative to traditional road grading, namely by allowing a road grader to carry a roller to simultaneously level and compact a ground surface, such as a gravel road.

  • Patent number: 5890545
    Abstract: An all electric riding bunker rake primarily suited for maintaining sand traps, or bunkers on a golf course. It is embodied as a tricycle-style vehicle having a frame supported on three wheels, an electrically actuated rake lifting mechanism at the rear of the vehicle supported by the frame, and a removable rake attachment connected to the rake lifting mechanism. The rake is dragged on the sand behind the vehicle to smooth the sand in a bunker. An electric motor drives the rear wheels through a gear box, and a regenerative type braking system works in conjunction with the electric motor to slow the vehicle whenever it exceeds eleven miles per hour when driven, or two miles an hour when unattended. The frame supports an onboard electrical battery power source and a hood to which a seat is attached on which the operator sits to control the operation of the vehicle and the rake lifting and lowering function.

  • Patent number: 4217707
    Abstract: In a snow plow having a horizontally elongated blade that extends lengthwise obliquely to the direction of plow travel, a snow retaining gate is mounted in front of the plow blade to swing flatwise about a horizontal axis near the top of the plow blade and substantially parallel to the direction of plow travel. When raised, the gate wall is substantially horizontal but has downwardly concave curvature from rear to front for close fit of its rear portion under the forwardly-upwardly curved upper portion of the plow blade. The rear edge of the gate wall has a curved upper portion so that when the gate wall is in lowered substantially upright position its rear edge, along the full height thereof, is contiguous to the front surface of the plow blade. When in lowered position the gate wall is oriented substantially parallel to the direction of plow travel and thus prevents formation of a secondary snow bank.
