817-084C Great Plains Coulter Bushing - Disc Pivot Bushing for Great Plains Grain Drill

817-084C Great Plains Coulter Bushing is high-quality black nylon bushing installed on the disc opener (coulter) assembly of Great Plains grain drills. This bushing serves as pivot support for the opener disc, absorbing side load and minimizing friction between moving parts. Worn bushings cause disc wobble, excessive joint play and inconsistent seeding depth, which directly affects uniform seed placement and emergence. Constructed from wear-resistant black nylon, this bushing resists abrasive soil and maintains stable clearances over long field use. It is a direct aftermarket replacement for OEM 817-084C, compatible with early model Great Plains grain drills including 2SF,3SF,3PD,EWNT and Solid Stand series. Install this coulter bushing to restore precise opener disc movement, eliminate wobble and improve planting uniformity for wheat, oats, barley and other small grains.
