Maintenance Tips
- Engine Oil & Filter: Change the engine oil and filter every 500 hours using the recommended John Deere Plus-50 II oil and a genuine John Deere oil filter to ensure optimal engine lubrication and longevity.
- Hydraulic System: Inspect hydraulic fluid levels regularly and change the hydraulic filter every 1000 hours or annually. Use only John Deere Hy-Gard hydraulic fluid to maintain the system's performance and prevent premature wear.
- Fuel System: Use a fuel conditioner additive to prevent fuel gelling and keep fuel injectors clean, especially during seasonal storage. Drain the water separator regularly to remove any accumulated water and prevent corrosion.
- Seasonal Storage: Before storing your tractor for the off-season, fill the fuel tank to prevent condensation, disconnect the battery, and store it in a cool, dry place. Grease all fittings and check tire pressure to prevent flat-spotting.
