Expert Maintenance Review

To keep your power transmission system in top condition, we recommend inspecting the variable speed pulleys for grooving or wear when installing a new rotor belt.

Standard preventative maintenance for this drive includes checking pulley alignment and ensuring the variable speed mechanism is fully greased. Replacing worn belts simultaneously ensures an extended service life for your threshing components and prevents costly downtime during the harvest window.
