Maintenance Tips

Engine Oil & Filter: Change your engine oil and filter every 250 hours of operation, using a high-quality oil that meets or exceeds the manufacturer's specifications. Regularly check oil levels.
Hydraulic System: Inspect hydraulic fluid levels and filters regularly. Change the hydraulic fluid and filter every 500 hours of operation, or more frequently if the oil appears dirty or contaminated.
Fuel System: Use clean, high-quality diesel fuel and replace the fuel filter every 250 hours. Drain any water or sediment from the fuel tank regularly. Consider a fuel additive for cold weather operation and to prevent gelling.
Seasonal Storage: Before storing your tractor for the winter, fill the fuel tank to prevent condensation, change the engine oil and filter, grease all fittings, and disconnect the battery. Store the tractor in a dry, sheltered location.
