Adjusting Belt Tracking

IMPORTANT: Check belt tracking before making any belt tracking adjustments.

If belts are new and have not been used, add oil dry or baby powder to simulate crop dust and allow belts to track freely.

NOTE: Check tracking with tractor at lowest RPM. Hold tractor hydraulic lever in gate closing position to apply tension to belts while checking.

1. If adjustment is needed, raise tension arm fully before adjusting rolls.

Light contact with belt guides is acceptable, but belts should not curl against guide straps.

Use small movements of No. 8 roll in slot. Let baler run at least 30-40 seconds to observe tracking between adjustments.
