  • Patent number: 5752735
    Abstract: A tarping apparatus for the open top container of a refuse handling truck has a pair of tarp deployment arms on opposite sides of the container that pull the tarp onto and off of the open top of the container as the arms are hydraulically swung back and forth along the container. One end of the tarp is anchored to a stationary mast at the front end of the truck body while the opposite end of the tarp is wound around a spring-loaded take-up roll that pays out the tarp as the arms are swung rearwardly and then automatically rolls up the slack as the arms are returned toward the front end of the truck. If necessary to accommodate dimensional variances between different size containers which may be carried by the truck, the pivot points for the deployment arms may be adjustably shifted by hydraulic cylinders either forwardly or rearwardly such that the arc of travel of the tarp roll is correspondingly displaced either forwardly or rearwardly.

  • Patent number: 4750441
    Abstract: A towable, furrow opening assembly has an intermediate opener and delivery tubes for deposit of materials such as seed into the opened furrow, together with a trailing press wheel and an aligned, leading wheel such that furrow depth is controlled by the wheels whose corresponding, articulated frames are looped over the opener. Buckling of the frames at the will of the operator varies the depth of the furrow.

  • Patent number: 4660651
    Abstract: In a drill, there is provided the combination of a pair of foldable pivot frames to each of which is attached a wheeled wing frame for up and down swinging movement, together with a tongue assembly for effecting the folding action, as well as a subframe for each wing made up of a T-frame and a hoe frame especially adapted for opening seed-receiving furrows and pressing the soil in each seeded furrow.

  • Patent number: 4535848
    Abstract: Wings of multiple section farm implements are folded by hydraulic cylinders each having a knee joint between the piston rod and a single arm which swings against a lug on the wing as the rod is actuated to lift the wing. A trunnion-notch arrangement operating in conjunction with a lost motion connection and an anti-jackknife device maintains a rod-arm interlock during a portion of each cycle of swinging of the wing to and from its folded position.

  • Patent number: 4250970
    Abstract: A farm implement has a mobile frame from which is suspended a number of chisel plow shanks and a row of rolling coulters ahead of the plows for cutting crop residue to prevent trash buildup and plugging at the plows. A transverse rock shaft on the frame is provided with swingable wheel arms and cranks to which hydraulic piston and cylinder assemblies are connected for raising and lowering the frame, and therefore, the plows and the coulters in unison. The coulters are swingably mounted on the frame for up and down movement relative to the frame as well as fore and aft movement toward and away from the plows. Turnbuckles pivotally interconnecting the coulter supports and the wheel arms impart swinging movement to the coulters during up and down movement of the frame. Accordingly, adequate slicing heights for the cutters are automatically maintained even at shallow plowing depths.

  • Patent number: 4232747
    Abstract: A farm implement has a number of normally horizontal sections for supporting ground-engaging tools, hingedly interconnected such that the outer sections may be folded upwardly and inwardly to a reduced width for transport and storage. A folding assembly separate from the hinges includes a hydraulic piston and cylinder power unit coupled with a lift link that is pivotally connected to a force-transmitting lever which, in turn, acts against a fulcrum during the folding operation. The fulcrum has the second function of serving as one of a pair of limiting stops in a lost motion arrangement for the lever which permits the foldable section to rise and fall in response to uneven terrain. The lever is supported through a trunnion by a carriage which, during folding, is first tilted by the lever to align the trunnion with slotted trunnion guide tracks and then shifted within a slide box by the power unit acting through the trunnion as the last phase of the folding operation takes place.
