Maintenance Tips

Engine Oil & Filter: Change the engine oil and filter every 250 hours of operation. Use a high-quality oil meeting John Deere's specifications and the correct filter for optimal engine performance.
Hydraulic System: Inspect hydraulic fluid levels regularly. Change the hydraulic fluid and filter every 500 hours to prevent contamination and maintain proper hydraulic function.
Fuel System: Use clean, high-quality fuel. Regularly check and clean the fuel filter to prevent fuel starvation and engine problems. Consider adding a fuel stabilizer during seasonal storage to prevent fuel degradation.
Seasonal Storage: Before storing the tractor for the winter, drain fluids or treat the fuel system, lubricate all grease fittings, and store the tractor in a dry location to prevent rust and corrosion. Disconnect the battery or use a trickle charger to maintain battery health.
