Cotton picker grid bars and pressure plates: check rubbing, damage and position
Bent or loose grid bars and an incorrectly positioned pressure plate need different checks. Locate contact marks and preserve the installed position before replacing spindles or ordering cotton-path parts.
Cotton picker cam-track wear or cabinet misalignment: which check is needed?
Replacing a roller will not resolve every track or cabinet problem. Separate track wear, mating-roller condition and cabinet geometry before choosing parts or attempting an adjustment.
