How do you adjust PTO air gap?

To adjust the PTO (Power Take-Off) air gap, first, ensure the engine is off and cool. Locate the PTO clutch and check the manufacturer's specifications for the recommended air gap, typically measured with feeler gauges. Adjust the gap by loosening the mounting bolts and using spacers or shims to achieve the correct distance, then re-tighten the bolts securely. Finally, recheck the air gap to confirm it meets the specifications.
