Abstract

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.

Claims

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; and

a lock nut on the adjustment bushing to maintain the gauge wheels in an adjusted position.

2. The row planter of claim 1 wherein the gauge wheels have an adjustable camber relative to the discs.

3. The row planter of claim 1 wherein the pivot bushing rotates within the pivot bushing.

4. The row planter of claim 1 further comprising a shaft having opposite ends to receive the adjustment bushings of the gauge wheels.

5. The row planter of claim 3 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 further comprising a slot in the frame and a pair of bolts extending through the slot to permit camber adjustment of the gauge wheels.

8. The row planter of claim 7 further comprising a collar pivotal about a horizontal axis and having an arm bolted to the frame via the slot.

9. The row planter of claim 7 wherein the collar resides between the gauge wheels.

20. The row planter of claim 6 wherein the camber of the gauge wheels is adjusted in unison.

10. 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; and

each gauge wheel having an adjustable camber.

11. The row planter of claim 10 wherein the gauge wheels are laterally adjustable relative to the discs.

12. The row planter of claim 10 further comprising a slot in the frame and a pair of bolts extending through the slot to permit the camber adjustment of the gauge wheels.

13. The row planter of claim 12 further comprising a collar pivotal about a horizontal axis and having an arm bolted to the frame via the slot.

14. The row planter of claim 12 wherein the collar resides between the gauge wheels.

15. The row planter of claim 10 wherein each of the gauge wheels includes an adjustment bushing to allow lateral adjustment of the wheels.

16. The row planter of claim 15 wherein each gauge wheel includes a pivot bushing extending into the adjustment bushing.

17. The row planter of claim 16 wherein each pivot bushing includes a grease zerk.

18. The row planter of claim 15 wherein each pivot bushing is threadably coupled to a center shaft.

19. The row planter of claim 15 wherein each pivot bushing pivots about a non-horizontal axis.
