  • Publication number: 20190166753
    Abstract: A reconfigurable tillage system that can perform multiple tillage functions in a single pass is provided. The reconfigurable tillage system of the present disclosure further manages the flow of soil passing through the system to ensure a uniform result without disturbing the surrounding land and without the distribution and/or build-up of soil outside the desired tillage pathway.

  • Publication number: 20130199807
    Abstract: A reconfigurable farm implement for tilling soil is described. The farm implement may comprise a frame having a plurality of mounting surfaces. A plurality of interchangeable tillage modules may be releasably coupled to the mounting surfaces. The interchangeable tillage modules may be arranged in a predetermined order based on a tillage requirement.

  • Publication number: 20040016554
    Abstract: The farm implement of this invention is movable across ground along a direction of travel for tillage. The farm implement includes at least a frame and a multi-disc unit. The multi-disc unit includes pluralities of first and second discs, each having a ground-engaging outer periphery defining a plane angled acutely relative to the direction of travel. The first discs are angled to an opposite side of the direction of travel than the second discs. Positioned between the plurality of first discs and the plurality of second discs is a first flow controller assembly, preferably a coulter assembly. Positioned behind the plurality of second discs is a second flow controller assembly, preferably a coulter assembly.

  • Patent number: 6554078
    Abstract: The farm implement of this invention is movable across ground along a direction of travel for tillage. The farm implement includes at least a frame and a disc/drive unit. The disc/drive unit includes first and second pluralities of discs, each having a ground-engaging outer periphery defining a plane angled acutely relative to the direction of travel. The first discs are angled to an opposite side of the direction of travel than the second discs. Positioned in front of the first discs is a ground-engaging driver rotatably coupled to the frame for rotating as the driver engages and is moved across the ground along the direction of travel. A driven flow controller is rotatably coupled and situated between the plurality of first discs and the plurality of second discs. The ground-engaging driver is operatively controlling and preferably accelerating the rotational speed of the driven flow controller.

  • Publication number: 20020000323
    Abstract: A cultivator apparatus includes a frame, a tube supported on the frame, and a plurality of cultivator rings loosely placed over the axis of said tube. The cultivator rings each include a tubular base including cylindrical interior and exterior circumferential surfaces, and a planer, ring-shaped blade presenting a circular interior circumferential edge and an opposed exterior circumferential edge. The interior edge of each blade is of a diameter slightly larger than the diameter of the exterior surface of the respective base, and each blade is welded to the exterior surface of the respective base along the interior edge. A method of constructing the rings is also provided.

  • Patent number: 5622227
    Abstract: A farm implement has a rigid frame from which is supported a mechanism for breaking and loosening compacted soil. A first plurality of S-tines are supported by the frame and disposed behind the breaking and loosening mechanism. Each S-tine has a sweep disposed on a lower end thereof. A reel is supported by the frame and disposed behind the first plurality of S-tines. The reel has a plurality of blades for chopping debris and breaking soil clods. A second plurality of S-tines are supported by the frame and disposed in offset rows behind the reel. Each S-tine has a sweep disposed on a lower end thereof. A roller mechanism is rotatably supported by the frame and disposed behind the second plurality of S-tines. The roller mechanism mixes and blends the soil with a rolling action. A finished roller breaks down remaining dirt clods and seals moisture in the ground.
