  • Patent number: 10087587
    Abstract: A skid steer rolling compactor attachment may include a universal attachment plate configured to attach to the skid steer. A boom extending from the attachment plate may pivot about at least one articulating hinge attached to the boom. The boom may be configured to move a roller to compact a ground surface as the skid steer travels in a forward direction. In order to prevent roll-overs on uneven surfaces, the skid steer may be operated on a level surface and articulate the boom such that the roller contacts the ground parallel to the direction of travel. The skid steer may then compact inclined surfaces while travelling on level surfaces thus improving worker safety.

  • Patent number: 5337834
    Abstract: An earth moving machine attachment is disclosed comprising a plurality of disk units mounted to a disk unit mounting beam which is fixed to a beam pushing frame for pivotally coupling to a dozer or tractor C frame. The beam pushing frame is angled obtusely in a clockwise or counterclockwise direction from the direction of push by a pair of reciprocal operating hydraulic cylinders to grade the earth materials to one side or the other of the C frame. The disk unit mounting beam and attached disk units are hingedly connected to a parallel offset shaft of the beam pushing frame for tilting the disk blades to provide restricted floatation on the earth materials. A sliding feature of the hinged connection between the disk unit mounting beam and the beam pushing frame accommodates hydraulic power means of shifting the load relative to the pushing axis of the earth moving machine.

  • Patent number: 5291954
    Abstract: A front folding tool carrier bar for agricultural applications includes a frame having opposite sides and having ground-engaging wheels mounter thereon. Mounted on the frame is a device for coupling the frame to a vehicle. Also mounted on the frame are a pair of forwardly folding wing bars having first and second ends, each of the first ends pivotally mounted on the frame such that the wing bars may pivot about a substantially vertical pivot axis between a forwardly folding transport position and a transversely extended working position. Each wing bar is pivotally mounted at opposite sides of the frame. For securing the wing bars in transversely extended working position, a pair of outrigger braces extend outwardly from the frame and are connected to opposite wing bars whereby the wing bars may be braced in working position. Mounted on each wing bar is at least one ground-engaging wheel. Finally, a device for pivoting the wing bars between the transport position and the working position is provided.

  • Patent number: 4945663
    Abstract: Planting mounds for afforestation purposes and the like are formed by an apparatus wherein a device having at least one mound-forming and compacting body is provided on a movable support arm or boom of a carrier vehicle adapted to be driven along the ground. The body has an elongate, longitudinally concave soil-pushing front surface of shape and dimensions suitable to define the upper surface of a planting mound, and preferably has digging teeth or the like at its lower forward edge. The body is supported for pivotal movement relative to the arm or boom and may be pivoted by a piston-cylinder assembly or the like. For mound formation, the body is placed in a digging position with the soil-pushing surface facing in a first direction substantially parallel to the ground.

  • Patent number: 4940096
    Abstract: A three point hitch mounted on the rear of a pick up truck has a pair of lift draft arms connected to a hay bale carrier. Pivot connections having upright pivot pins attach the lift draft arms to a transverse shaft allowing the lift draft arms to be folded adjacent each other below the rear bumper of the truck. Crank arms secured to opposite end of the shaft are connected to hydraulic piston and cylinder assemblies. The piston and cylinder assemblies are operable to rotate the shaft to selectively raise and lower the lift draft arms and bale carrier mounted thereon.

  • Patent number: 4899831
    Abstract: Improved tractor frontal three-point connection apparatus with lower links attached to the front bolster at a pivot axis behind the front panelling of the tractor housing and pivotable to positions behind such panelling, the lower links having rear extensions acted on by lower ends of substantially vertical hydraulic cylinders to pivot the lower links to a substantially vertical orientation, thereby facilitating movement of lower links to inoperative positions over the front axles. Preferred embodiments include a tubular rock shaft rotatably mounted on the front bolster and having rearwardly extending cylinder-attachment lugs, opposite ends removably receiving journals of the lower links, and pocket members at each end receiving and interacting with the rear extensions of the lower links.

  • Patent number: 4896489
    Abstract: An implement lift system for a machine such as a front mouted mower having a pair of transversely spaced lift arms operable by a single life cylinder. The lift cylinder is transversely adjustable utilizing a special cylinder bracket arrangement and a transverse member extending between bend locations on the lift arms forwardly of the pivotal connections of the lift arms with the vehicle. The transverse member is connected to provide lift to both arms from the single cylinder while permitting independent vertical movement of each of the arms. Compensation for unequal forces acting on the lift arms can be provided by moving the cylinder laterally to achieve even lift and flotation characteristics.

  • Patent number: 4817728
    Abstract: Implements designed for attachment to a lawn and garden tractor include elongate attaching frames having the implement tool connected to first ends of the frames and transport wheels located so that the weight of the implement is distributed approximately half on opposite sides of the wheel axes so that the implement may be easily pushed about on the wheels during mounting and dismounting the implement to and from the tractor frame. Attachment brackets and lift links of the implements are engageable with attachment pins and lift crank arms of the tractor without necessitating any lifting of the implement. Also with driven implements, the drive belts are arranged on or stored with the implements so that the tractor drive may be easily and correctly connected.

  • Patent number: 4773666
    Abstract: A three point or other hitch for use in conjunction with a tractor, preferably for mounting onto its front end, a pair of side plates permanently mount onto the front side edges of the tractor, each side plate incorporating shaped cradles for holding the hitch thereto. The hitch incorporates laterally extending trunions for mounting onto the side plates, and the lift arms of the hitch have a stabilizing plate arranged intermediate thereof, in order to provide enhanced support. Each lift arm incorporates a clamp, at their frontal ends, with each clamp incorporating a support for holding a draw pin, and a dog associated with each clamp for locking the pin into position, but which can be manipulated by a cam for holding the respective dogs out of their locking position, so that any implement can be freed therefrom.

  • Patent number: 4431061
    Abstract: A farm implement adapted to be coupled to the front of conventional tractors for pre-cutting or scalping old levees. A rigid, box-like frame is secured generally transversely upon the front of the tractor. The frame supports an elongated, rigid channel mount extending generally perpendicularly with respect thereto. An elongated, rigid stanchion may be coupled to the channel mount to elevate a first hydraulic cylinder attachment point at a desired elevation above ground. A plow assembly includes a pair of rotatable, angularly disposed forwardly projecting cutting discs rotatably secured to a central frame, and an elongated rigidly upwardly extending strut terminating at its top in a second point for connection with a hydraulic cylinder. Rigid strut guide means are secured about the channel mount at a desired elevation, sandwiching the stanchion therewithin.
