PIVOTING GAUGE WHEEL
First Claim
1. A wheel assembly for an agricultural implement comprising:
- a bracket coupled to an implement frame;
a ground engaging wheel supported by a pivot assembly to permit pivoting of the wheel about a non-horizontal axis;
a support tube coupled to the pivot assembly and configured to be coupled to the bracket at a plurality of positions to define a height adjustment of the wheel; and
an extendable adjustment assembly having a first portion coupled to the support tube and a second portion coupled to the bracket to enable adjustment of the wheel height prior to coupling of the support tube to the bracket at one of the plurality of positions.

Abstract
Embodiments of the invention provide an innovative arrangement to control the height of ground engaging tools located on agricultural implements via gauge wheel assemblies, particularly for supporting and adjusting the height of winged extensions of the implement frame. The gauge wheel assemblies may provide an adjustment assembly in the form of a screw jack, which can be coupled to a support bracket that is attached to the implement frame and also coupled to a support tube that is coupled to a gauge wheel via pivot assembly and a bracket. The bracket and support tube may be coupled at discrete positions according to the height adjustment of the screw jack via pins and holes in the bracket and tube. When coupled, the pins and holes of the support bracket and tube may reduce the load of the winged extensions on the screw jack mechanism.

19. An adjustable wheel system for an agricultural implement, comprising:
-
a bracket configured to be coupled to an implement frame and having a plurality of position holes formed therein; a ground engaging wheel assembly having a pivot mount; a support tube configured to be selectively coupled to the bracket at a plurality of positions corresponding to the position holes to define a height adjustment of the wheel; a pivot assembly coupled to the support tube for securing the ground engaging wheel to the support tube and to enable the ground engaging wheel to pivot about a non-horizontal axis, the pivot assembly having a pair of pivot supports configured to receive the pivot mount of the wheel assembly, the pivot supports being generally bilaterally symmetrical to premit the wheel assembly to be mounted on either side of support tube; and a height adjustment assembly having a first portion coupled to the support tube and a second portion coupled to the bracket to permit adjustment of the wheel height prior to coupling of the support tube to the bracket at one of the plurality of positions. - View Dependent Claims (20, 21)
