Agricultural furrow forming apparatus depth control

Abstract

An apparatus to be towed that includes a frame supported, rotatably mounted, pair of furrow forming disks that are arranged to substantially contact each other at the approximate point of entry into the soil and diverge apart rearwardly and upwardly, a pair of rotatable gauge wheels having supports that individually and pivotally connect the wheels to the frame with each wheel being located generally adjacent an outer surface of a disk, a gauge wheel adjustment assembly slidably mounted in said frame and having an equalizer assembly connecting the supports whereby movement of a support and thus wheel in one direction produces the same movement of the other support and wheel in a contrary direction and including an indicator, furrow depth indicating structure having a zero position and spaced indicia for indicating furrow depth and adjustment structure for movably mounting the indicating structure on the frame, and structure for selectively immobilizing the equalizer assembly in a neutral position whereby with the wheels in the lowest position and resting on a level surface and then raised until the disks contact the level surface and the zero position being located opposite the indicator by the adjustment structure and secured to the frame, accurate depth control is achieved when the equalizer assembly is released for furrow forming.
