Abstract

Gauge wheels control the depth at which seeds are placed during planting operations. Planter gauge wheels are mounted on gauge wheel arms which become dusted with soil during normal operation. An improved gauge wheel arm described herein includes first and second hubs extending from either end of a shaft. Each hub forms a cylindrical body between first and second faces. The first hub has a central channel through the cylindrical body, and a bearing is press-fit within the central channel. A retaining ring is fitted over the bearing, within an interior groove formed proximate the first face of the central channel, to retain the bearing within the central channel. The improved gauge wheel arm described herein reduces build-up of dirt and frictional wear, thus increasing both the life span of the arm and its associated parts, and decreasing time spent greasing and adjusting gauge wheel arms.
