Adjust Belt Tracking

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

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

   NOTE: Check belt tracking with PTO engaged and tractor at lowest rpm. Hold tractor hydraulic lever in gate closing position to apply tension to belts while checking.

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

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

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

   2. Lower gate slowly until belts are slack.

   3. Lock the gate.

   4. Shut off tractor and remove key.
