  • Publication number: 20110147018
    Abstract: A tillage blade having a sharpened outer peripheral edge on a blade body has a predetermined thickness. An annular portion of the blade is disposed between the outer peripheral edge and the body having a thickness which is less than the thickness of the body of the blade, the annular portion having a radially outer part and a radially inner part. The blade is tapered from the sharpened peripheral edge to the radially outer part of the annular portion and the blade is tapered from the radially inner part of the annular portion to the body. By making the sharpened bevels on out outer periphery of the blades taper in steps instead of just sharpening them by making either one bevel on one side, or a bevel on each side of the outer periphery of the blade, the blade will last longer than prior art tillage blades.

  • Patent number: 5964049
    Abstract: A trencher has an adjustable depth arbor support mechanism. The depth control mechanism includes a linkage which normally controls the depth of the trench being dug, but which also will allow the arbor to retract from the ground if it hits an obstacle. Preferably, the arbor support mechanism is at least partially counterbalanced by a spring, to allow the arbor to retract without undo force. The trencher has two wheels equidistant on either side of the arbor, and a third steerable wheel at the front of the trencher in line with the arbor. The cutting teeth are mounted to the arbor using a variety of chucks and mounting brackets, so the width of the trench is adjusted by adjusting the chucks and mounting brackets used.

  • Patent number: 5222562
    Abstract: An attachment for use with an agricultural implement to protect a row of emergent plants growing in a field. The device includes a shield which protects the plants from accumulations of soil, trash, and other debris. The shield is mounted between one or more claws of the implement, on one hand, and the row of plants to be protected on the other hand. Means, such as a motor, are provided to drive the shield in a plane generally parallel to the row of plants. As the shield is positively rotated, a periphery of the shield passes closely proximate the surface of the ground in which the row of plants is located. Such driving of the shield is in a direction in which the shield would rotate if it were allowed to freewheel and were made to rotate as a result of its engagement with the ground.

  • Patent number: 5038868
    Abstract: A cultivation implement which is comprised generally of forward and rear thatching reels which rotate in opposite directions relative to each other under positive drive power from a tow vehicle, such as a tractor. Each reel unit is rotatably disposed in its own carriage or frame, which carriages are hingedly connected to each other and to said tow vehicle. Each carriage rides, when the implement is not in use, on free spinning road wheels. For use, each carriage may be selectively lowered from the non-use, raised, position to a lowered, in-use, position, by actuation of hydraulic means. To assure even and smooth operation of the implement while the reel units are engaging the ground, unique ground engaging members, or skids, are connected to each carriage and positioned relative to each said reel unit so as to be interengaged by the vertical blade members.
