With Separable Vertical Cutter On Centerline Patents (Class 172/725)
  • Patent number: 6332412
    Abstract: A ground-engaging paired row furrow forming tool includes a tool body having fore and aft ends with an outer edge defined on each of two opposing sides of the tool body. A furrowing wing is located adjacent each of the opposing sides and protrudes from bottom portions of the tool body. The tool body has lower surfaces including a central front surface portion which is angled upwards towards the fore end and a center passage is defined between the furrowing wings. This passageway is in part defined by a central rear surface portion which is adapted to be substantially aligned fore to aft in a direction of travel T during operation of the ground engaging tool. This paired row opener works well without compromise in a broad range of soil conditions without fouling and enables planting of seed rows spaced widely apart while minimizing soil surface disturbance.

  • Patent number: 5730228
    Abstract: A row cultivator (10) includes a row following system (12) coupled to a toolbar (13) employing frame members (17) and (18) constrained to remain parallel by a cross member (21). Coulter wheels (30) and (31) secured to the frame members (17) and (18) are non-steerable and tool bar drift may be corrected. A tool (40) employs a leading blade (44) and a pair of diverging cutting blades (47) and (48) trailing behind the leading blade (44). A sheer release assembly employs a longitudinally extending bolt (70) centrally disposed and holding a shank (61) to a tool bar (65) so that when a tool on the shank (61) strikes an underground obstacle the bolt (70) is sheared longitudinally.

  • Patent number: 5456323
    Abstract: An agricultural sweep for being attached to a tractor for pulling the agricultural sweep across the ground. The agricultural sweep incudes a ground engaging portion having a cutting edge for cutting through the ground as the sweep is pulled across the ground; a stem portion for attaching the ground engaging portion to a tractor; and an extended wear portion applied to the stem portion for rendering the stem portion resistant to abrasion.

  • Patent number: 4605089
    Abstract: A target member of the seismic energy source is driven into ground surface engagement, as the vehicle, to which the seismic energy source is pivotally connected, moves, due to the target member geometry, that is by resolving the tractive force so that the force driving the target member into the ground is a vector directed at an angle less than 90.degree. to the direction of the vehicle movement. Impulses from an impulse generator are transmitted to the target member after the latter has been driven into the ground, during the vehicle movement or at rest. The impulses are transmitted to propagate in a plane parallel to the ground surface and perpendicularly to the direction of the target member movement.

  • Patent number: 4415042
    Abstract: In the agricultural industry, one cultivator wheeled cart cultivator implement has a vertical ripper blade for use in ripper cultivating the soil usually between rows of growing crops. The vertical blade has its front edge sharpened. There is usually a lower point to the blade. Such sharpened front edge portion of the blade which is drawn through the ground, as well as its lowermost point, wear out rapidly, as a result of cultivating in gravelly or hard soil, and have to be replaced often on comparatively small use. Such replacement heretofore required the use of complicated bolt securement of parts, at the front edge and lower ends of the cultivator ripper blade, and the parts to accomplish that replacement are needlessly numerous and complicated and expensive.

  • Patent number: 4208974
    Abstract: A seed drill (FIG. 1 ) having a frame (1 ) with knife hoes (7 ) mounted thereon. The knife hoes are movable in a vertical plane and each has two laterally projecting wings (8 ) bent downwardly toward one another; the outer edges of the wings merge forwardly together to form a point. Each knife hoe has an upright strut (13 ) supporting the leading point of the knife. Further, each knife hoe is disposed on a shank (9 ) which is mounted on the frame with parallel guide means (10 ). The parallel guide means has at least one articulation (19 ) acting in a vertical plane, a stop (21 ) limiting forward swinging movement of the knife hoe about the articulation, and at least one resilient element (22 ) exerting a force on the knife hoe in the direction of the stop. The drill further includes a gauge wheel (16 ) for each knife hoe to limit the depth of penetration of the knife hoe into the soil.

  • Patent number: 4142588
    Abstract: Plowshares and double moldboards which form listers are attached to shanks connected to a toolbar or frame drafted behind a towing vehicle. Rotatable stabilizing discs, or colters, are rigidly affixed to the shanks behind the moldboards and plowshares. The discs engage solid soil behind the moldboards, thereby impeding lateral movements of the plowshares and moldboards and stabilizing the listers.
