1. A planting apparatus for a drawn grain drill comprising:
- a. a drawbar adapted to be attached at a forward end to a drawbar shaft of a grain drill for pivotal movement therewith;
b. a pair of opposed, furrow forming disks rotatably mounted on said drawbar;
c. means adapted to be connected to the drill and connected to said drawbar for forcing said disks into the soil;
d. a seed tube located between said disks and extending toward the furrow for depositing seed therein, said tube being adapted to be connected to a seed dispenser; and
e. a press gauge wheel assembly mounted on said drawbar rearward of said disks for closing the furrow and compacting the soil on the seed, said assembly comprising;
a bracket mounted on said drawbar, an arm pivotally supported on said bracket, a wheel rotatably mounted on said arm, and a rearwardly facing adjustment means mounted on said bracket having a rotatable handle portion and a gear set for transferring said rotation to a generally vertical plane to said arm to control wheel position and hence furrow depth in response to force applied to said drawbar.
