Abstract: A vehicle-attached lifting device and tool support is provided. The device comprises a dual-rail frame supported in an upright configuration by the vehicle tow hitch, wherein an internal subassembly support frame is positioned between the rails for the purposes of supporting different lifting and tool support subassemblies. Along the sides of the upright frame is a pair of ground support members that extend downward towards the ground to support the frame during operation, preventing the load from compressing the vehicle suspension or damaging the same. A winch controls the vertical positioning of the support frame within the dual-rail frame, which controls the position of a lifting or tool support subassembly. Many subassemblies are contemplated for use with the present invention for the purposes of assisting a user without requiring manual input therefrom. The device can also adjust with relation to the vehicle using different trailer hitch attachments.

Abstract: A vehicle-mounted tool, such as a blade, may be disposed in an upright position for dozing or other pushing functions when the vehicle moves forwardly and then flipped over into an inverted position for back-dragging or the like when the vehicle moves in reverse. Flipping of the blade is accomplished using a cylinder operated from the seat of the vehicle. The blade is mounted on a swivel head that is controlled by a pair of oppositely actuating swivel cylinders from the operator's seat so that whether the blade is upright or inverted, it may be swivelled left or right into any number of obliquely disposed positions.
Abstract: An apparatus, system and method for moving a scraping device are provided. The scraping device has a frame, a blade attached to the bottom of the frame, a tongue attached to a front end of the frame and a beam attached to a back end of the frame. Tires are connected to the beam. The scraping device has a front lift mechanism at the front end of the frame and/or a rear lift mechanism at the back end of the frame. The front lift mechanism has a front cylinder connected to the tongue and the front end of the frame. The rear lift mechanism has a rear cylinder attached to the back end of the frame. Movement of the front cylinder and the rear cylinder results in raising and/or lowering of the corresponding ends of the frame of the scraping device. Raising and/or lowering of the front end and/or the back end of the frame adjusts the angle of the frame relative to the ground, adjusts the angle of the blade relative to the ground and/or adjusts the ground clearance of the scraping device.
Abstract: The lawn aerating vehicle has front and rear steering sections, each of which supports an aerator drum. Each drum has multiple cutting tines extending radially outward for soil penetration during the aerating process. A hydraulic motor and a belt or chain drive connected to the front drum propel the vehicle. Steering actuators provide pivotal torque to the drums for steering. A hydraulic pump and reservoir provide hydraulic power to the hydraulic motor and actuators. A cylindrical member forms part of a vehicle suspension by connecting the rear and front steering sections. Frame members and an operator's cab are disposed above the suspension and can be pivoted around the cylindrical member to provide cab leveling by means of a cab leveling actuator. The two drums provide for double coverage per pass. External vehicle lights permit operation during nighttime and otherwise poor visibility conditions.

Abstract: A towable scraper system for contour surface grading. The system includes a rigid chassis member that has a coupler configured for attachment to a conventional three-point tractor hitch. A scraper blade is pivotally suspended from the rigid chassis member and is equipped with a blade motivator for causing an angular rotation of the blade around an axis aligned with a towing direction. A lift assembly raises and lowers the rigid chassis member to control a height of the scraper blade relative to a work surface to be graded. The towable scraper system is provided with a carriage assembly that offers rolling support for the rigid chassis as it moves over the work surface. The carriage assembly is pivotally coupled to the rigid chassis at a location opposed to the coupler and is configured for angular rotation around a second axis aligned with the towing direction.
Abstract: An energy conservation system for an earth-moving loading machine is comprised of one or more pressurized gaseous pistons that extend from the front of the frame of a loading machine to the boom assembly. Although this piston does not provide sufficient force to maintain the boom assembly in a raised position, a portion of the weight of the boom assembly and associated payload is always supported by the piston. This energy conservation system thus decreases the hydraulic horsepower needed to raise and lower the boom assembly and payload, or, in the alternative, decreases the cycle time required to raise and lower the boom assembly. The energy conservation system of the present invention into a loading machine also allows for a more controlled lowering of the boom assembly.
Abstract: An apparatus and method for blending and windrowing hot plant mix asphalt which has been deposited onto a roadway in preparation for paving the roadway comprises a V-shaped plow formed by a first plowing member extending in a first direction, and a second plowing member extending in a second direction, with rearward ends of each of the first and second plowing member being connected at a vertex and the opposite forward ends being spaced apart to form the open side of the V-shaped plow. The V-shaped plow further comprises an opening in the vertex and a movable gate for adjusting the size of the opening in the vertex. The V-shaped plow is further provided with an attachment device for attaching the V-shaped plow to an earth moving implement, such as a front end loader. Movement of the V-shaped plow along the roadway causes the hot asphalt to be thoroughly blended and deposited from the opening into a perfect windrow having the desired amount of asphalt for paving the roadway at issue.
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.

Abstract: A single lever blade control apparatus for bulldozers that is capable of operating in three mutually perpendicular planes to activate three independent hydraulic valves controlling a bulldozer blade: up/down, tilt and angle. Movement of the bulldozer blade in an up/down motion is accomplished by the operator by pushing the single lever apparatus in the X direction, the X direction corresponding to the longitudinal axis of the bulldozer. Movement of the bulldozer blade in the tilt direction is accomplished by the operator pushing the single lever apparatus in the Y direction. Angling the bulldozer blade is accomplished by the operator rotating the handle of the single lever apparatus about the Z axis. The invention works with all variations of hydraulic valve placement.
