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 to regulate furrow depth, with each wheel being located generally adjacent an outer surface of a disk, and an equalizer assembly connecting the supports so that movement of a gauge wheel by an obstacle upward produces an equal movement of the other gauge wheel downward to produce a frame height and hence related furrow depth that is the average between the gauge wheel elevations.
