  • Patent number: 6557646
    Abstract: An agricultural tillage implement employing a series of apparatus to perform one-pass primary tillage is disclosed. A cutting disk is the first apparatus that works the field. These disks cut the residue laterally (across the machine) and mix the majority of the residue throughout the disk tillage profile. Additional conditioning occurs by knocking residue/stalks over into a prone position with large cast spools between each disk for quicker decay. Next, chisel plow units work the soil to fracture and loosen the soil, providing proper soil aggregate size and air pore space relationship throughout the shank tillage profile. The last apparatus to work the field is a set of leveling disks, or a combination of leveling disks and a rotary reel/drag harrow. The function of these will provide is to reduce clod size and leave the soil level and smooth enough to allow one-pass secondary tillage in the spring.

  • Patent number: 6199637
    Abstract: A movable implement for loosening soil below ground, in which a row of blades with blade holders are located perpendicular to a direction of motion of the implement. A supporting arm has one end articulated to each blade, and a frame is articulated to another end of the supporting arm. The supporting arm is engaged by a connecting rod of a crank device, which operates in a vertical plane parallel to the direction of motion. The supporting arm mounts a blade adjustment lever with two arms. The adjustment lever pivots coaxially with an articulating shaft. A stop is mounted on a downward-extending arm of the blade-adjustment lever, and points below the articulating shaft. A lever-adjusting device has a variable angle to the supporting arm for varying the angle of the blade to the ground. A spring forces a blade holder against the stop. The blades are forced away from the stop during movement of the implement.

  • Patent number: 5695012
    Abstract: A deep subsoiler (50) consists of a plurality of carriages (58) abreast on a frame (52) and a plurality of shanks (60) mounted on each of said carriages. The mounting for each of said shanks provides a fail-safe mechanism consisting of a pair of rosettes (72) with shear-bolts (86). Said rosettes enable the operator to minutely set an angle of attack for each shank tip (P37). Said carriages align parallel with a direction of travel. Each shank on the carriage functions at an increasing depth which provides a staged sequence with a shortest shank (60c) in a forward position. Theory and tests indicate a draft reduction using staged shanks. Said tips for these shanks produce larger voids in the subsoil and increase the flow of subsoil to the surface. Staged shank standards (P40) cut narrower grooves in the surface that inhibit rivulets. The larger voids hold more water and organic material and this material adheres better to the surface.
