Abstract: A seeding system includes a frame mounted on ground wheels for moving across the ground together with a plurality of individually mounted seeding elements carried on parallelogram linkages from the frame. A seeding element includes a walking beam arrangement having a single front wheel and a pair of rear wheels straddling the seeding sweep positioned between the front and rear wheels. The rear wheels act as packer wheels for two rows of seeds. The walking beam system lifts a main support frame of the seeding element against the bias from a pressurized controlled hydraulic cylinder. The seeding sweep is mounted upon a trip shank. The seeds are supplied through a tube which splits at the sweep to deposit the seeds into the cavity within the sweep on either side of the center line of the sweep. A fertilizer banding knife projects downwardly and rearwardly from the lower end of the shank to a position rearwardly of the sweep.

Abstract: A scraper is provided for use on depth gauge wheels provided on planters for row crops such as corn, soybeans, cotton, beans, peanuts and the like. The scraper includes a scraper blade which is mounted at one end portion of an elongated arm for contacting the outer circumference of the depth gauge wheel. The other end of the arm is mounted by a bearing assembly to a hub provided on the depth gauge wheel. The bearing assembly is mounted coaxially with the axis of rotation of the wheel so that the arm remains stationary as the wheel rotates. In addition, the scraper blade remains in contact with the wheel as the wheel is moved in vertical and fore-and-aft directions. A support bolt is also received within an elongated opening presented by a U-shaped member mounted at the free end portion of the scraper arm to stabilize and reduce unnecessary movement of the scraper arm.

Abstract: A mud scraper assembly includes a scraper blade mounted on the lower end of a scraper arm which in turn has a clamp at its upper end mounted on the sleeve of a depth gauge wheel support arm. No alteration of existing planter structure is required for adapting the mud scraper assembly to a Deere Max-Emerge planter and planters having generally the same structure. An adjustment screw is provided on the clamp for engaging the wheel support arm at a point remote to the shaft axis on which it is mounted to pivot the scraper arm into close proximity with the depth gauge wheels as needed.

Abstract: A depth gauge wheel removably secureable to a coulter disc to control the cutting depth of the disc, the wheel formed of a high density plastic to which soil and other debris will not adhere.

Abstract: Disclosed is an apparatus for controlling the depth of soil penetration of a ground contact implement, such as a planter, furrow opener, seeder, tiller, fertilizer or pesticide applicator, plow, etc. or any combination thereof. The present invention permits presetting of a desired ground contact implement soil penetration depth, and provides continuous dynamic regulating of an adjustable downpressure system in response to changing forces exerted on the device (for example, including those forces resulting from soil unevenness), so as to maintain the ground contact implement at approximately the preset desired depth.

Abstract: Fertilizer or other liquid crop treatment is applied to the ground using a direct injection jet with a nozzle position closely adjacent the ground and forming a jet of the liquid directed into the ground. A solenoid controlled valve cyclically halts the flow of fluid to form short pulses of the fluid so that the fluid can be supplied in concentrate form while generating sufficient energy to achieve a depth of penetration in the range 2 to 4 inches. The solenoid controlled valve and nozzle is mounted on a skid member carried on a depth control wheel. The period of the pulses is arranged so that the length of a pulse is very short relative to the spacing between the pulses with the spacing between adjacent rows formed by adjacent heads being substantially equal to the spacing between the individual pulses.
