First Claim
Patent Images
1. An agricultural seed planting implement, comprising:
- a ground penetrating assembly;
an adjustable gauge wheel supporting said ground penetrating assembly at controlled penetration depths;
a depth control linkage arm adjustably positioning said gauge wheel;
a handle connected to said depth control linkage arm for axially positioning said depth control linkage arm, said handle being rotatable about a longitudinal axis thereof; and
a depth adjustment register including a pair of notches, each notch of said pair of notches engaged by said handle in a first rotational orientation of said handle for establishing a first depth for said ground penetrating assembly and in a second rotational orientation of said handle for establishing a second depth for said ground penetrating assembly.
