Abstract
The planer row unit has a unit frame with a front member that is adapted to be secured to a tool bar. A sub frame is secured to the front member by parallel links. A furrow opener disk, a seed shoe and a gauge wheel are secured to the subframe. A cam plate supported by a spring to the rear of the seed shoe presses seeds into moist soil in the bottom of a seed furrow. A seed covering disc is supported by a covering disc shank to the rear and to one side of the furrow opener. The covering disc has a circular plate portion that faces downwardly and forwardly, moves loose soil from the furrow opener into the seed furrow and rotates about a central axis that extends downwardly from a horizontal plane. A flange, with notches extends radially outward and rearwardly from the outer periphery of the circular plate portion, rolls and slides along the surface and limits soil penetration by the covering disk.
