Equalized furrow forming apparatus for a seed planter

Claim 1

A furrow forming apparatus for a seed planter comprising: (a) a frame, said frame being adapted to be attached for towing to a mobile power source; (b) a pair of opposed, furrow forming disks rotatably mounted on said frame with the disks substantially contacting each other at the approximate point of entry into the soil and diverging apart rearwardly and upwardly to the direction of travel; (c) a pair of gauge wheel means individually mounted on said frame forward of said disks for regulating furrow depth, each means comprising: a support pivotally mounted on said frame, a wheel located generally adjacent an outer surface of a disk and rotatably mounted on said support on an axis rearward of the disk axis of rotation; and (d) equalizing means, pivotally mounted on said frame and extending between and positioned forward and adjacent said 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 where the lower wheel will fall to the soil and the movement of its support will be away from the equalizing means when out of the equalizing range.
