Abstract
A disc opener system for attachment to an agricultural vehicle for opening a seed trench. The system includes a main arm, a disc opener mounted to the main arm, a gauge wheel mounted about a pivot axis to the main arm, a gauge wheel mounted for rotation on the gauge arm, and a depth adjustment assembly for adjusting and positively locking a position of the gauge wheel relative to disc opener. The depth adjustment assembly includes an adjustment link mounted to the main arm, an adjustment coupling attached to the gauge arm, a handle pivotably attached to the adjustment coupling and a clip attached to the adjustment coupling. The clip locks the handle in a position where it mates the adjustment link and adjustment coupling to fix the position of the gauge wheel relative to the disc opener.
