  • Patent number: 4781129
    Abstract: A debris and soil shaver for no till farming is disclosed which has a disk-like member which floats up and down as it is pulled across the ground surface. The disk is angled with respect to a predetermined direction of travel of an agricultural apparatus which is adapted to pull the shaver. The disk is rotatably mounted to a first support member about a central transverse disk axis. The first support member is pivotally mounted to a vertical second support member about a pivot axis. The pivot axis and central transverse axis are angled with respect to one another. The second support member is clamped to the agricultural apparatus which pulls the shaver. With such a construction, pivotal movement of the first support member about the pivot axis causes the angle of the disk relative to the ground surface to change. The angle adjusting prevents the disk from engaging too much soil and allows the disk to seek a path of least resistance as it rolls across a planting field.

  • Patent number: 4650005
    Abstract: A row crop cultivator for use in farming which includes a pair of weeding disks associated with each cultivator unit of which a plurality is ganged together in series. Each weeding disk is bearingly supported by a vertical shaft which is received by a cross bar in a manner which permits the shaft associated with the weeding disk to be adjusted as to depth and angular orientation. Such changes in the vertical shaft for the weeding disks are directly transferred to the weeding disk itself. Disposed adjacent the uppermost point of the shaft is a degree gauge plate and adjacent thereto is a depth gauge structured out of angle iron. As the farmer makes adjustments as to angular orientation and depth of one weeding disk, he need not be concerned with the specific values until the optimum depth and angular orientation have been found for the particular field being cultivated.

  • Patent number: 4597452
    Abstract: A disk grading terrace plow comprising a plurality of disk units mounted below an angled beam frame which is towed at an angle of 40 to 45 degrees to the direction of tow via a tractor connected to an elevated hitch beam mounted to the said angle beam frame in a lateral position which balances draft torques. Alignment of the said disk units, each comprising a disk blade, shank and attachment structure, along the angled beam frame is such that dirt is excavated from a furrow and discharged both vertically and laterally in front of the next sequential rearward disk. The excavated dirt then continues to shift from disk-to-disk in a compound grading manner until all the dirt is shifted around the rearmost disk blade. The depth of cut for the disk grading terrace plow is controlled by adjusting hydraulic cylinders connected to a front and rear gauge wheel, respectively.

  • Patent number: 4515224
    Abstract: A seed drill apparatus comprising at least two complementary rotatable seed discs journalled in tandem relation whereby one of the discs is a leading disc and the other of the discs is a trailing disc. The plane of each disc is canted with respect to the direction of travel for the apparatus, with the plane of the leading disc being of an orientation opposed with respect to the orientation of the plane of the trailing disc. The canted position of the seed discs creates a combined plowing and grooving action for the disc as the apparatus moves over the surface of the ground, thus opening and widening an efficient seed receiving groove in the ground regardless of whether or not the ground has been prepared by plowing, or the like.

  • Patent number: 4489787
    Abstract: For cutting the roots of weeds in agricultural fields, rolling knives in the form of flat, circular plates with sharp, peripheral edges are journaled to struts connected to a tool bar drafted in a direction of draft. The knives rotate about knife axes that are normal to knife planes containing their sharp edge. All knife axes are about 45.degree. from vertical. For bedded fields, the rolling knives are preferably connected to the tool bar in knife sets of two for each soil bed, with the knives of each set engaging opposite sides of each bed. As the rolling knives roll within the soil, their sharp edges sever the roots of weeds. In an alternate embodiment, a vertical stabilizer plate is rolled opposite each rolling knife to stabilize the soil therebetween. In another embodiment, each strut includes a hinge that has a hinge axis substantially within the knife plane. The knives swing about the hinge axes and trail in the direction of draft following the path of least resistance through the soil.
