The Land Pride 122-202S Press Wheel Adjustment Trunnion Assembly is a press wheel depth adjustment component used in seed drills and planters to control how deeply seeds are placed in the soil. A worn or damaged trunnion assembly causes the press wheel arm to shift position unpredictably, resulting in inconsistent seed depth, uneven emergence, and reduced stand uniformity across a field. This replacement assembly restores precise depth control so the press wheel holds its set position through the entire planting pass.
