Adjust Belt Tracking

1. Check belt tracking before making any belt tracking adjustments.

   If belts are new and have not been used, add granular oil absorbent (oil dry granules) to simulate crop dust and allow the belts to track freely.

   Check belt tracking with the PTO engaged and tractor at lowest rpm. To apply tension to the belts while checking, hold the tractor hydraulic lever in the gate closing position.

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

   If an adjustment is needed, slacken the belts by doing the following procedure:

   1. Raise the gate fully so the tension arm is against the stop.

   2. Lower the gate slowly until belts are slack.

   3. Lock the gate.

   4. Shut off the tractor and remove the key.
