摘要：

An assembly for adjustably mounting a gauge wheel arm to the frame of a row unit may include a pivot pin connected on the frame, a bushing freely rotatably mounted on the pivot pin for engagement with the gauge wheel arm such that rotation of the bushing with respect to the gauge wheel arm moves the gauge wheel arm axially, and a locking element that integrates the gauge wheel arm with the bushing so that there is no relative movement therebetween as the gauge wheel arm rotates with respect to the pivot pin.
