Abstract: An improved material pusher or containment plow employing a floating vehicle-coupling system, a modular composite scraping edge, a front-pivoting wear shoe with an adjustable angle, as well as water-shedding features. The disclosed containment plow and features are provide improved the surface outcome under various snow and ice conditions.

Abstract: A materials pushing or moving blade for use with heavy equipment vehicles, for example, a bulldozer or loader, and more specifically to a method and apparatus for moving snow, specifically a snow moving blade having a reinforcing gusset for strengthening the extended sidewalls of the snow moving blade.

Abstract: The present invention is an apparatus for use on large areas such as parking lots and airport runways to remove snow and other debris or material therefrom. The apparatus includes at least two blades pivotally connected to one another, and mounting receptacle or bracket having a series of pairs of posts extending from the rear thereof to facilitate operational attachment to a loader or similar construction equipment. The present invention further includes improvements to enable the segmenting and automatic folding of the pusher.

Abstract: A snow plow includes a central blade and left and right end blades pivotally connected to the ends of the central blade for movement between open positions in line with the central blade, and folded positions forward of the central blade. The rear of the central blade includes a horizontal slot for removable insertion of a loader bucket to lift and drive the plow. Side walls extend forward from the outer end of each end blade, each side wall including a removable wear shoe for sliding contact on a ground surface. The end blades are lockable in both their open and folded positions.

Abstract: The present invention relates to an apparatus for use in conjunction with a machine, such as a wheel-mounted loader, road planing machine or the like, to equalize the effect of ground-surface irregularities. The apparatus includes a frame disposed in the movement direction of the machine and a planing tool. The apparatus also includes a bogie-assembly which is mounted on the front end of the frame and extends parallel to the frame. The bogie-assembly includes two pivot wheels and a linking device which is pivotally mounted between the frame and an intermediate unit connected to the planing tool.

Abstract: A mine clearing rake comprising a rake assembly with alternately disposed large and small teeth which are arranged to form a broad "V" and are rigidly supported laterally by horizontally disposed bars and rods to provide a maximum proportion of open space rearwardly and are supported rearwardly by a rigid reinforcing frame assembly which is attached to the bottom edge of the moldboard of a propelling vehicle, such as a tank, and have four additional points of support and/or attachment to the moldboard. An extension grid assembly is also mounted above the rake assembly to prevent unearthed mines from rolling over the mine clearing rake. A skid shoe assembly is attached to the reinforcing frame assembly and protrudes through the rake assembly so that the skid shoe rests upon the surface of the minefield during operation of the mine clearing rake.

Abstract: Blade mechanisms being operated along the ground have a tendency to draft into the ground unless some positive form of control is provided to prohibit the downdrafting of the blade. In the subject arrangement, a blade and linkage mechanism is provided for stopping a blade from drafting downward with respect to the ground. The linkage mechanism includes a tilt arm attached between a work vehicle and a top portion of the blade and a push arm attached between the work vehicle and a bottom portion of the blade. The tilt arm is movable relative to the vehicle through an arc which if extended intersects the push arm between its pivot connections. When the blade drafts downward, the different orientations of the tilt arm and the push arm corrects the downdraft due to the rear of a skid plate attached thereto being tilted with respect to the ground. The changing orientation of the skid plate with respect to the ground causes the front of the blade to raise with respect to the ground.

Abstract: Plowing means for dislodging, uplifting and sweeping aside mines are attad to a crossbeam and located on either side of float shoes that slide along the ground and adjust to maintain a chosen depth of plow. The crossbeam is connected to the front of a vehicle by pushbars that attach to a frame mounting on the vehicle. The float shoes are caused to move by powered adjusting means mounted on the crossbeam and controlled by sensing means that monitor the attitude of the vehicle relative to the pushbars and generate a control signal for maintaining the plow depth.

Abstract: Mine clearing equipment mountable on a vehicle. Two plow sections arranged one above the other in hinged engagement are included in apparatus which mounts on a frame and by which mines are raised and shunted aside. The frame in turn is mountable onto the vehicle in raised or lowered orientation. In the frame raised position, the plow sections are in folded engagement. The raising and shunting aside apparatus is angularly oriented with a forward edge adjacent the vehicle interior and a rearward edge adjacent the vehicle side edge. A chain is attached to the forward edges and plow sections in tension when the plow sections are lowered into their operating orientations to define mine barriers.

Abstract: An excavator has an undercarriage supported on three pair of driven ground wheels. The middle pair of wheels is disposed lower than the remaining wheels so as to enhance the skid-steering ability of the excavator. A dozer blade is mounted to the front of the undercarriage. A caster wheel assembly is mounted to the outer end of the excavator boom and actuators associated with the latter are operable to bring the caster wheel into ground contact ahead of the blade and to exert a down-pressure sufficient to cause the undercarriage to rock rearwardly about the middle pair of wheels to a stabilized condition, where the excavator weight is carried by the middle and rear pair of wheels. Grading operation can be done when the undercarriage is in its stabilized condition.

Abstract: A quickly attached and removed adjustable grader blade attachment for a bucket of a bucket vehicle, which includes a blade, and an adapter bracket and frame assembly that will permit the blade to be angularly adjusted by hydraulic or mechanical means and a bucket bottom engaging member that will serve as a cutting depth control for the grader attachment.

Abstract: A rake for use with tractors has a blade connectable to a tractor and a plurality of teeth extending from the bottom of the blade. The teeth are pivotally connected to permit movement of the teeth away from objects encountered when the tractor moves. Fluid piston and cylinder combinations interconnect the teeth with the blade so movement of the teeth displaces pressurized fluid within the piston and cylinder combinations. The pressurized fluid reverses the pivotal movement when the teeth clear the objects.

Abstract: A plow attachment assembly for a crawler-type tractor having an elevatable "C" frame which includes a first "V" shaped plow adapted to be rigidly secured to the "C" frame, a second "V" shaped plow which is roller supported for movement over the ground disposed ahead of the first plow and connected to the latter by a strut, the forward end of which is rigidly secured to the second plow and hingedly secured to the first plow for vertical swinging movement and a pair of telescopic spreader arms extending rearwardly from the second plow and having a hinged connection to the "C" frame for moving debris spread by the first plow laterally on opposite sides of the tractor and for levelling top soil plowed by the second plow laterally in the path of the tracks of the tractor.
