Towed Scraper With Ground Support Wheels Patents (Class 172/799.5)
  • Patent number: 10039225
    Abstract: A land roller implement includes a wheel aligned with the respective gap between the inner roller and the outer roller of each wing in which the wheel is pivotal between a packing position in the working position of the rollers and a transport position supporting the rollers in the transport position of the implement. The wings can also include a drive motor associated with each transport wheel to drive forward rotation of the wheel for displacing the wings from the transport position to the working position without displacing the implement in a rearward direction. A levelling beam attachment and a seeding attachment can also optionally be used on the land roller implement. Optional latchable brace members pivotally supported on the wings may provide additional support to the wings when using the levelling beam attachment.

  • Publication number: 20140331527
    Abstract: A ditching apparatus features front blade sections fixed to the frame in a V-configuration, and a pull tongue extending over the blade apex to a pivotal connection near a rear of the frame. An actuation mechanism effects relative pivoting between the frame and the pull tongue to adjust an angle between the front blade and the trailer tongue to control a ground-penetration depth of the blade apex. Two rear blade sections on opposing sides of the frame are movable between deployed positions extending rearwardly and laterally outward from the front blade sections, and stowed positions elevated out of the deployed positions. The blade angle and width are thus controllable to achieve a desired depth and width of ditch. A nose cap at the blade apex provides an improved ground breaking action, while internally braced blade structures will roll formed skins provide durability and smooth rolling action of displaced earth.

    Abstract: An agricultural implement includes a traction structure and a tool beam rearward of the traction structure. First and second wheeled support structures support the tool beam at opposite respective ends of the tool beam. First and second linkages each have a forward portion connected to the traction structure and rearward portions connected to the first and second support structures respectively. An actuator is effective between the traction structure and the first linkage for selectively adjusting an angular position of the first linkage relative to the longitudinal axis of the traction structure. The tool beam provides a force transmitting connection between the rearward portions of the first and second linkages whereby angular movement of the first linkage relative to the traction structure is accompanied by angular movement of the second linkage relative to the traction structure.

Next is a pair of soil-gathering blades that capture and gather the loose soil and residue together and to create a berm of a mixture of soil and residue. The last apparatus to work the field is a rotary reel that conditions the strip of soil to give ideal seed-to-soil contact and uniform berm size.

    Abstract: A snowplow apparatus as adapted to attach to a vehicle having a ball hitch assembly. The snowplow apparatus has a blade assembly connected to an elongated drawbar. A frictionally activated elevating mechanism is operatively connected to the drawbar and moves between a vertical and non-vertical orientation depending upon whether elevation of the blade or contact with the blade and the ground is desired, respectively. A further aspect relates to a lateral stabilization device associated with the opposite end of the drawbar, such stabilization device coming into contact with static members operatively associated with a hitch ball such that lateral movement of the drawbar is substantially precluded due to the contact between the stabilization members and the static elements.

  • Patent number: 6328115
    Abstract: A wheeled dirt scraper having a pair of stabilizer rails pivotally mounted onto each of the side wings of the box, the rails being provided with damping devices to reduce, absorb and eliminate shock effects. The rails have a relatively large surface contact area and extend substantially the length of the wings. The rails are mounted such that the lower surfaces can pivot below or even with the bottom edges of the wings, so that the rails can remain in contact with the ground even when the wings are suspended above the ground.

  • Patent number: 6286608
    Abstract: This invention relates to an invention of a novel detachable garden type chisel plow that is towed behind a small farm or garden tractor unit. This invention has an independent self raising gas pressurized lift jacks mechanism attached to one chisel point shank plow which can be easily lowered by the tractor operator using the plow engagement rope. The lifting device of this invention utilizes two gas pressurized lift jacks thereby avoiding the need for a hydraulic system or other power lift system. The novel apparatus of this invention also has the capability to receive and utilize additional optional attachments such as a tilling disk apparatus, drag chain attachment, and useful farming other like devices. The apparatus of this invention works with a small farm or garden tractor unit equipped with a plate or bar tow capability having only a small diameter hole in the tow plate or tow bar and does not require a three point hitch or type of lift mechanism.

  • Patent number: 6206106
    Abstract: A grader to enable high speed grading for gravel or unmade roads having a plurality of grader blades the position of each blade being maintained in a forward most grading position by an hydraulic ram which is hydraulically connected a gas accumulator. The blades are collectively supported by a draft frame the height of which is changeable by a hydraulic ram also coupled to the gas accumulator. Each blade, when in its forward most position, is rearward of the axis of the pivot support for the leg supporting that blade.
