Depth control for seed planter
First Claim
1. A disc opener assembly connected to a tool bar linked to a vehicle for movement over the ground for opening a seed trench therein, the assembly comprising:
- a main arm member attached to the tool bar;
a disc mounted for rotation on the main arm;
a gauge arm member having proximal and distal ends, the proximal end mounted for pivotal motion about a pivot axis to the main arm member;
a gauge wheel mounted to the distal end of the gauge arm member;
a first coupler mounted to one of the main arm member and the gauge arm member;
a second coupler linked to one of the main arm member and the gauge arm member and juxtaposed proximate and for movement with respect to the first coupler along a coupling axis that is substantially parallel to the pivot axis, the second coupler configured to engage the first coupler when biased there against; and
a retainer for maintaining the first and second couplers engaged.
