Plural Runner Supported Implements Relatively Movable During Operation Patents (Class 172/392)
  • Patent number: 6401832
    Abstract: Lift wheel structure for an implement includes four bar linkage having a curved lower link connected to the frame closely adjacent a first tool-carrying rank. A caster wheel is supported at the forward end of the linkage for castering in an accommodation area defined by the curved lower link. Plates are bolted to the sides of the lower link and extend along sides of an upper link to a connection with a lift cylinder directly above the upper link. The link and the cylinder closely overlie the frame to limit interference with other components mounted above the frame and to facilitate compact folding of implement sections. Loads, including cylinder lift loads, are transmitted primarily through the lower link. A protected transducer assembly is connected between the lower link and the frame to maximize and linearize transducer response in the depth control range.

  • Patent number: 4422392
    Abstract: A seed drill has rotatably mounted opener discs disposed in an acute angle with respect to the direction of travel and mounted on supports. A skid is mounted to each support at the outside surface of the disk at an angle with respect to the direction of travel. Each skid includes a trailing portion configured to have a sliding surface disposed above the depth of penetration of the disk in the ground and a leading portion bent upwardly in the direction of travel and having a recess in the side thereof facing the disk and which extends beyond the forwardmost portion of the disk in the direction of travel.

  • Patent number: 4341027
    Abstract: At least one trailing scraper member freely swingable within a vertical plane is provided, which has a scraper blade and a scraper base disposed at an acute angle relative to the blade. The angle of adjustment of the scraper member relative to the snow surface over which the device travels is adjustable, so that the scraper member either removes snow from the snow surface or slides over same. Associated with the scraper member is a scooping device limited by side walls and by a shield which can be lifted or lowered, in order to collect the snow provided by the scraping member and to transport same to another location and discharge same on lifting of the shield.

  • Patent number: 4328629
    Abstract: A device for protecting shellfish dredge chain bags, featuring arcuate strips of reinforced rubber attached to the bottom side of the bag to cushion and separate the bag from abrasive action against the ocean floor when it becomes weighted with rocks and shellfish. These arcuate strips are cut from used vehicle tires and are attached to the chain bag in a manner that protects the forward edge and corners of the strip and the attaching device from catching on the ocean floor while allowing the longer portion of the reinforced rubber strip to trail beneath the chain bag.

  • Patent number: 4051792
    Abstract: A structural orientation and protective apparatus is disclosed that is particularly useful in a tillage assembly for sod seeding purposes. The apparatus includes a pair of skids each of which is adjacent to a cutter wheel mounted on the tillage assembly for cutting a furrow in ground to be seeded, each skid including a ground engaging portion to determine the maximum depth of furrow cut by the cutter wheel. Each skid is mounted for pivotal motion about a horizontal axis at the forward end, with the forward end being inclined upwardly from the ground engaging portion. A vertical mounting plate on each skid has a bracket mounted therebetween at the rear portion to receive a vertical adjustment rod, one portion of which is connected to the frame of the apparatus for controlling the selected depth of furrow to be cut. A seed tube boot is fastened to the rear portion of the skid so that regardless of the selected depth of furrow cut, the tube remains in the same position relative to the ground.
