Abstract

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.

Claims

1. In an agricultural row unit having a frame and a pair of gauge wheel assemblies connected to the frame, each gauge wheel assembly including a gauge wheel rotatably connected to a distal end of a gauge wheel arm for rotation about an axis, an assembly for adjustably mounting a proximate end of each gauge wheel arm, which has an internally threaded bore, to the frame comprising:

a pivot pin connected to the frame;

a bushing rotatably disposed on the pivot pin and having an externally threaded portion that engages the threaded bore in the gauge wheel arm such that rotation of the bushing with respect to the gauge wheel arm facilitates movement of the gauge wheel arm along a longitudinal axis of the bushing; and

a locking element engaging the gauge wheel arm and the bushing so that there is no relative movement therebetween as the gauge wheel arm rotates with respect to the pivot pin.

2. The adjustable mounting assembly of claim 1, where the locking element is a threaded fastener.
