Maintenance and Service Considerations for the John Deere 9660

Check and replace the engine oil at regular intervals based on operating hours. This helps ensure optimal engine performance. Use the recommended John Deere oil and replace the filter each time to prevent any buildup of contaminants.

Inspect the air filters at least once a season. If they appear clogged or dirty, clean or replace them to maintain engine efficiency and prevent dust and debris from entering the engine system.

Monitor the grain handling system for any signs of wear. Check the augers and conveyors regularly for damage or misalignment. Any irregularities should be addressed immediately to avoid further damage and downtime.

Lubricate all moving parts such as bearings and joints at the specified intervals. This minimizes friction and reduces the risk of premature wear on critical components.

Check the hydraulic system for leaks and replace any worn hoses or fittings. The hydraulic fluid level should be monitored frequently, ensuring it stays within the recommended range. This helps maintain smooth operation of the header and other hydraulic-driven systems.

Inspect the cooling system, including the radiator and coolant levels. Clean the radiator fins to prevent overheating. Regularly flush the cooling system to remove any debris and buildup, ensuring the engine operates at the correct temperature.

Test the electrical system, including batteries and connections. Clean battery terminals and ensure they are tight. Replacing batteries that show signs of deterioration will prevent electrical failures during operation.

During the off-season, store the combine in a dry, sheltered location to protect it from the elements. Perform a thorough cleaning of the machine to remove dust, crop residue, and other contaminants that may affect performance when it is used again.
