DEPTH ADJUSTMENT ASSEMBLY FOR A DISC OPENER OF AN AGRICULTURAL IMPLEMENT
First Claim
1. A disc hub assembly for a disc opener apparatus having a coulter, comprising:
- a spindle having a first end and a second end;
a depth adjustment arm coupled to the first end of the spindle and adapted to be selectively positioned at one of a number of depth setting positions, wherein rotation of the depth adjustment arm causes rotation of the spindle;
a gauge wheel arm coupled to the second end of the spindle and configured to rotate with rotation of the spindle, the gauge wheel arm having a first end coupled to the second end of the spindle and further having a second end; and
a gauge wheel spindle coupled to the second end of the gauge wheel arm and adapted to be received by a depth setting gauge wheel such that rotation of the spindle causes either a lowering or a raising of the depth setting gauge wheel relative to the coulter.

Abstract
A disc hub assembly includes a shouldered spindle that is secured to a disc opener frame and to which a depth adjustment arm and a gauge wheel arm are connected. The disc hub, to which a ground opener disc is mounted, is disposed on the spindle in a manner that allows the disc to rotate around the spindle. A gauge wheel is connected to the gauge wheel arm. When the depth adjustment arm is rotated between depth setting positions the gauge wheel arm is also rotated. As the gauge wheel is connected to the gauge wheel arm, rotation of the gauge wheel arm causes rotation of the gauge wheel. The depth adjustment arm is spring biased into engagement with an arc of notches on the disc opener frame. The notches define a range of positions at which the depth adjustment arm may be positioned.
