Maintenance Tips

Change engine oil and filter every 250 hours using the recommended oil type and a genuine John Deere or quality aftermarket filter.
Regularly inspect and service the hydraulic system, checking for leaks and replacing filters according to the manufacturer's recommendations. This prevents costly hydraulic pump or valve damage.
Keep the fuel system clean by using high-quality fuel and replacing fuel filters as scheduled. Consider using a fuel additive to prevent gelling in cold weather.
Before seasonal storage, drain the fuel tank, add a fuel stabilizer, and ensure the tractor is stored in a dry location. This helps prevent corrosion and fuel degradation.
