Abstract: A cultivator shovel for mounting on one of the shanks of a conventional agricultural cultivator. The shovel includes a shank mount in the form of a channel for receiving the shank therein. A shovel body is supported on a lower end of the shank mount and includes a leading edge extending rearwardly and outwardly from opposing sides of a forward apex to respective rearward free ends of the shovel body. A pair of upright end plates are mounted on the shovel body adjacent the respective rearward free ends. The end plates prevent deflection of weeds about the free ends of the shovel body when the shovel is used for weeding, thus forcing the weeds to be broken on the leading edge of the shovel body or on the end plates for more effective weeding using a cultivator. Furthermore, soil disturbance is increased dramatically using the end plates, and as a result, shallow rooted weeds such as millet die.

In one embodiment, a row side sweep includes a row side wing angled upwardly from the horizontal at an angle of approximately 27 degrees, and the opposite wing is angled downwardly, to closely match the profile of the ground from the row bed to the row middle. In another embodiment of the invention, a wide sweep extends between the beds of adjacent rows and includes wings with outermost portions bent upwardly at an angle with respect to the horizontal to provide a sweep profile which closely approximates the ground profile between the rows for more uniform depth of penetration, less soil throw and crop root damage, and reduced draft.

Abstract: A rig assembly on a combination row crop cultivator and chemical applicator includes a knife or other applicator device supported in front of the cultivator sweep and behind the disk coulter blade. The sweep helps seal the chemical in the ground in certain soil conditions to prevent chemical loss, particularly when additional closing structure is not in use. A selectively attachable, shank-mounted closing mechanism, preferably a press wheel, may be mounted directly behind the sweep to assure a good chemical seal. Disk coulter support straps have flanges that provide a conveniently accessed mount for the applicator device and present minimal interference to trash and soil flow. A simple bracket connects an arm on the closing wheel mechanism to a central portion of the sweep standard. Numerous combinations of tools and tool mounting arrangements and adjustments are facilitated by the rig construction.

The tillage unit's lower bottom-most edges are shaped and positioned to allow incresing clearance proceeding from front to back between the tillage unit 1 and the uncut soil below to allow for adjustment of the operating incline of the soil-contacting blade surface attached to the face of the blade support assembly 2 where the tillage unit 1 is fastened to the carrier frame 18.

Abstract: An opener assembly for fertilizing, tilling and seeding in one pass. An opener body is removably attached to an upright support leg and mounts a replaceable fertilizer banding knife. A replaceable sweep blade fixed immediately behind the knife to slice weed roots and firm the seedbed. A seed plenum located above the sweep blade receives a stream of seed through a channel in the opener body and divides the seed into left- and right-hand rows which are sown over the firmed soil. The forward central portion of the sweep is notched and is received over the opener body closely adjacent to the fertilizer knife to provide a compact structure, and a mounting tab at the rear of the sweep cooperates with a bolt and captive nut arrangement to provide quick and easy replacement of the sweep. The entire opener body may be removed from the support leg to change an implement from one type of operation to another.

Abstract: An improved plow point such as used on a chisel plow has a forward tooth for breaking the soil. Wings extend outwardly and rearwardly of the tooth portion of the tool at a shallow angle. That is, the leading edges of the wings slope downwardly and slightly rearwardly from the tooth. After the tooth breaks the soil, the wings raise, twist and turn the broken deep soil. This lifting action provides aeration of the soil. The wings also bring up some deep soil and leave large chunks of soil that become mellow due to the freezing and thawing cycles during the winter. The outboard rear edge of each wing may be turned slightly downward which enhances the twisting motion of the soil. All of this is done without creating a plow sole.

Abstract: A cultivator has a frame normally carried on the back of a tractor and pulled in a predetermined direction along the ground. A plurality of tines extend downwardly from this cultivator and penetrate the ground. Each tine is pivotal about a respective axis perpendicular to the direction of travel and parallel to the ground and is biased into a normal central position by means of a respective hydraulic actuator. The cylinders of all of the hydraulic actuators are connected together in a closed network so that if one tine is forced backwardly the other tines will be urged correspondingly forwardly and vice versa. In addition each such tine, which also may be mounted on a parallelogrammatic linkage, may carry a V-shaped backwardly extending blade increasing the mixing and aeration effect of the cultivator.

Abstract: This invention relates to an improved soil contact tool comprised of a narrow uniform width ground engaging section and a triangular moldboard section extending therefrom.

Abstract: An apparatus is disclosed for injecting fertilizer into the soil. A soil working device includes a sweep with a nose portion that moves through the soil as the sweep is moved forward, a pair of trailing sections that diverge from the nose portion, and an upstanding mounting portion for mounting the sweep to a shank extending from the frame of an agricultural implement. A pair of wings extend rearwardly from the trailing sections of the sweep so as to be at opposite sides of a channel formed by the sweep. Each wing has a front portion that flares outwardly from the trailing section of the sweep and a rear portion that is inclined inwardly from the back of the front portion. Fertilizer is injected into the channel formed by the sweep and soil engaged by the wings is urged toward the channel to cover the same and enhance fertilizer retention in the channel.

Abstract: A replaceable blade yoke holder, carried by an adapter clamp, comprising a pair of parallel horizontal wedges, with the wedges adapted to be removably held together by bolt holding means, and with certain of adjacent outer edges of the wedges being adapted for replaceably holding a cultivator blade tool there upon bolt holding securement of the wedge together and with an edge of one of the wedges being reinforced with a carbon steel member secured at a ninety degree angle thereto to resist a bending of that wedge upon such bolt holding means securement of the wedges together.This invention relates to replaceable blades in the farming industry, and more particularly to the type of a cultivator blade which is drawn through the ground a short distance below the surface of the ground. Such a blade usually has a point, and a cutting edge to cut the ground at a required depth. Use of the blade over a comparatively short period of time results in a dulling of the blade and requires that it be replaced.

Abstract: A knife for applying substances such as fertilizer in solid, liquid or gaseous form cuts a slice in the subsoil with its leading, rearwardly inclined cutting edge and simultaneously firms up and maintains the lower portions of the sides of the slice in readiness for receiving the substance in a pocket formed by a recess at the lowermost rear of the knife in conjunction with the firmed up portions. The slice taken by the slender knife is of such narrowness and the movement of the knife through the subsoil is of such a streamlined nature that the cohesive integrity and inherent resiliency of the subsoil is not destroyed, promoting self-closure of the slice behind the knife, thus greatly reducing the escape of the substance where it is a gas.
