| 41 | Row crop cultivator including disk and setting indicator therefor | US566040 | 1983-12-27 | US4607705A | 1986-08-26 | John A. Tebben |
| 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. The vertex edge of the depth gauge serves as a pointer for the graduations on the degree gauge plate, while the top surface of the degree guage plate serves as a pointer or alignment marker for the graduations on the depth gauge. 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. Once this has been determined for a single weeding disk, all other disks of the cultivator can be almost instantly set to the same indicator values thereby duplicating the desired depth and angular position of the corresponding disks. | ||||||
| 42 | Rotary hoe stripping means | US710237 | 1976-08-02 | US4100971A | 1978-07-18 | Darrel Lee Honnold |
| A pair of loosely coupled trash stripping rings are carried in face to face contact with sides of a rotary hoe wheel to continuously strip field trash accumulations from the hoe tines during cultivating operations. In operation, engagement with the ground continuously forces the stripping rings upwardly against the hoe hub and trash buildup on hoe tines opposite those tines engaging the ground is slidably scraped off by the upwardly moving stripping rings. | ||||||
| 43 | Forward angle plow sweep with elevated trailing wing edge | US584194 | 1975-06-05 | US4026367A | 1977-05-31 | Robert C. Tibbs |
| A plow sweep construction comprising a generally horizontal plate is provided. The plate includes front and rear marginal edges extending longitudinally of the plate and the center portion of the rear marginal edge includes an integral rearwardly and upwardly projecting mounting shank portion spaced substantially centrally intermediate the opposite ends of the plate and provided for attachment to and support from a tool support member. The front marginal edge portion defines a substantially horizontal edge facing forwardly and the, blade member, at least for the most part, is transversely rearwardly and upwardly inclined. The mounting shank portion includes a lower end portion merging smoothly into the longitudinal central portion of the blade member and the lower end portion and the longitudinal central portion of the blade member, including the front marginal portion thereof, being forwardly convex. Still further, the front marginal edge portion of the blade member includes generally straight relatively angulated opposite end portions defining a forwardly opening included angle of between 90.degree. and 180.degree. with the preferred included angle lying between 135.degree. and 170.degree.. The portions of the rear marginal edge portion of the blade member on the opposite sides of and adjacent the lower portion of the mounting shank portion are downwardly depressed so as to be generally horizontally disposed. | ||||||

A plurality of parallel linkages movably connect a transverse tool bar to the beam. Row guide units having longitudinally aligned guide wheels and furrowing tools are mounted with clamps to the tool bar. Earthworking tools are mounted with clamps to the tool bar. In one form, the earthworking tool is a blade sequentially moved into and out of the soil with a lifting wheel to dig water and snow holding basins or trenches in the soil. | ||||||
| 45 | Tillage implement | US3770066D | 1971-11-18 | US3770066A | 1973-11-06 | YOUNG A |
| A special tool is designed to trail behind a conventional cultivator sweep or other soil loosening device in the middle of the furrow between rows of growing crops. The implement is hinged in a horizontal plane to the back of the sweep and is adjustable as to height and width. The implement clears the furrow of loose soil between the rows of the growing crops and shapes the furrow and pushes the dirt to the row to cover small weeds.

| 53 | Tool apparatus with tool attached to end of outrigger arm | US938269 | 1986-12-05 | US4936390A | 1990-06-26 | Jack F. Anderson; Jeffrey N. Anderson |
| A three-point hitch mounted in-row tiller has a conventional three-point hitch mounted frame member with an outrigger arm pivotally mounted to the frame member in a manner that accommodates pivotal movement of the outrigger in relation to the frame member about two orthogonal axes. Pivotal movement about one of the axes causes tilting of a working tool mounted on the outrigger arm, and pivotal movement about the other axis causes vertical lifting and depth control of the working tool. Various working tool embodiments, including several with flexible teeth, and a mechanical/hydraulic sensor apparatus are also included. | ||||||
