Row planter with adjustable gauge wheels
Adjustable gauge wheels are provided on a row unit planter adjacent the opening disc. The wheels are adjustable laterally for proper spacing adjacent the discs. The camber of the gauge wheels relative to discs is also adjustable. The lateral adjustment is accomplished via a wear bushing and pivot bushing extending into the wear bushing for each gauge wheel. A grease zerk is provided on the end of each pivot bushing to supply grease to the inside of the adjustment wear bushing. The camber adjustment is accomplished via a slot in the row planter frame and bolts extending into arms on a pivotal member.
1. A row planter, comprising:
a frame,
a pair of discs on the frame to form a furrow in the ground;
a pair of gauge wheels adjustably mounted on the frame;
each gauge wheel including an adjustment bushing and a pivot bushing so as to be laterally adjustable relative to the discs;
a lock nut on the adjustment bushing to maintain the gauge wheels in an adjusted position; and
a tubular member pivotal about a horizontal axis and having a pair of arms bolted to the frame via a slot in the frame and a pair of bolts extending through the arms and the slot to permit camber adjustment of the gauge wheels.
2. The row planter of claim 1 wherein the adjustable camber is relative to the discs.
3. The row planter of claim 1 wherein the pivot bushing rotates within the adjustment bushing.
4. The row planter of claim 1 further comprising a shaft having opposite ends to receive the pivot bushings of the gauge wheels.
5. The row planter of claim 4 wherein the ends of the shaft define offset axes such that the gauge wheels angle inwardly from top to bottom.
6. The row planter of claim 3 wherein the pivot bushing extends into the adjustment bushing.
7. The row planter of claim 1 wherein the tubular member resides between the gauge wheels.
8. The row planter of claim 1 wherein the camber of the gauge wheels is adjusted in unison.
