Abstract
A gauge wheel assembly includes a gauge wheel arm that straddles the rig tube and is supported on the tube by two bushings inserted through holes on either side of the tube. The bushings contact each other near the center of the tube to provide a solid or hard joint which permits the pivot bolt to be tightened without crushing the sides of the tube. The bushing has protrusions that are pressed into the tubing wall during installation and thereby prevent bushing rotation. Two different straps at the lower end of the wheel arm permits at least three different combinations of gauge wheels to be quickly and easily mounted. A compact and easily accessible depth adjusting crank is supported entirely above the rig tube. A depth indicator projects from the crank trunnion mounting on the upper end of the wheel arm to provide an indication of depth adjustment.
