Abstract
A mounting assembly for a gauge wheel on a row unit allows for infinite lateral adjustment of the gauge relative to an opening disc on the row unit. The mounting assembly includes an arm with a threaded bore extending through a split end of the arm. A threaded bushing is adjustably mounted in the bore and secured in a desired position with a bolt standing through the split end to clamp bushing in position. The split end mounting arm provides a method of quickly and easily adjusting the lateral position of the gauge wheel on the row unit in infinite increments.
Claims17
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 each being adjustably mounted on the frame via an arm;
- each arm having a split head with a first threaded bore and a second bore transverse to the first bore;
- each arm including an adjustment bushing threadably extending through the first bore and so that the arm and gauge wheel is laterally adjustable relative to the discs;
- and
- each arm having a bolt extending through the second bore and a nut tightenable on the bolt to clamp the adjustment bushing in the first threaded bore.
A mounting assembly a gauge wheel on a row planter, comprising:
- an arm having opposite first and second ends;
- a threaded bore extending through the arm at the first end;
- a slot extending from an outer surface of the arm at the first end to the threaded bore so as to define a clamp with spaced tips on the first end of the arm;
- a hole extending through the clamp tips;
- a bolt extending through the hole;
- and
- a nut threaded on the bolt to tighten the claim tips.
A method of laterally adjusting a gauge wheel on an agricultural row unit, comprising:
- mounting the gauge wheel on a first end of an elongated arm;
- mounting a split second end of the arm to the row unit using a first bolt extending through a bushing threaded into a bore in the second end of the arm;
- tightening a second bolt extending through holes in the split second end of the arm so as to fix the bushing against rotation in the bore.
