For operators requiring consistent and reliable performance, the 3720’s hydraulic system is both easy to maintain and efficient in powering essential attachments. Routine checks of the fluid levels and ensuring the system is free of leaks will help maintain its longevity and lift capability.
Maintenance Requirements and Service Intervals
Change engine oil every 100 hours or at least once per year. Use high-quality, manufacturer-approved oil to maintain optimal engine performance. Clean or replace the air filter every 50 hours of operation or more frequently in dusty environments.
Inspect the fuel system regularly, ensuring all filters are clean. Replace the fuel filter after 200 hours of use or as specified in the operator’s manual. Check the fuel lines and connections for leaks or damage at each service interval.
Grease all grease points every 50 hours to prevent premature wear of moving parts. Pay special attention to the front axle, transmission, and steering components. Inspect the hydraulic system for leaks and ensure fluid levels are within recommended ranges.
Inspect tire pressure every 50 hours. Keep them properly inflated to avoid uneven wear and to maintain tractor stability. Replace tires when tread depth reaches the manufacturer’s specified limit.
Check the battery’s charge level and inspect for corrosion every 100 hours. Clean terminals and ensure the battery is securely mounted to avoid electrical issues. Replace the battery when it shows signs of significant wear or poor performance.
Keep an eye on the coolant level. Top up or replace coolant as necessary to avoid overheating. Flush and replace the coolant every 2 years or 500 hours of operation.
Inspect the brake system at each service interval. Ensure the brake pads are in good condition and that the brake fluid is topped up. Replace worn components as needed to maintain braking efficiency.
