Maintenance and Service Requirements for the 4720 Model

Check and change the engine oil after every 100 hours of operation. Use John Deere’s recommended engine oil for optimal performance. The oil filter should also be replaced during this service interval.

Inspect the hydraulic system every 250 hours. Ensure that hydraulic fluid levels are within the recommended range, and replace the fluid and filters every 1,000 hours. Pay close attention to the hoses and fittings for any signs of wear or leaks.

Inspect the sprayer’s boom every 500 hours of use. Check for any damage or wear on the tips, arms, and supports. Clean all nozzles thoroughly to avoid clogging and ensure even spraying.

Maintain the air conditioning system by replacing the cabin air filter every 250 hours. Regularly check the coolant level and ensure the radiator is free from debris to prevent overheating.

Inspect the wheel bearings and axles regularly. Grease the bearings every 100 hours of operation to prevent wear and ensure smooth movement.

Check the battery condition every 100 hours. Ensure that the battery terminals are clean and free from corrosion. If the battery’s charge is low, recharge it promptly to prevent starting issues.

Monitor the tire pressure and wear. Keep the tires inflated to the manufacturer’s recommended pressure to ensure proper handling and reduce wear. Rotate the tires periodically to promote even wear.

Ensure all safety features, including lights and warning systems, are functioning correctly before each use. Regularly test the operation of the sprayer’s electrical systems to avoid unexpected failures.
