Maintenance and Service Guidelines

To maintain the John Deere 300 Corn Picker in optimal condition, perform regular inspections and servicing. Keep the machine clean and lubricated to prevent wear and reduce the risk of breakdowns.
- Engine Maintenance: Change the engine oil every 100 hours of operation. Replace the oil filter at the same interval to ensure proper lubrication and cooling of the engine components.
- Hydraulic System: Check hydraulic fluid levels regularly and replace the fluid at least every 500 hours. Inspect hydraulic hoses and connections for leaks and replace any damaged parts immediately.
- Greasing: Grease all moving parts, including the chain drive and header, every 50 hours of operation. Use a high-quality grease recommended by John Deere to prevent friction and extend the life of components.
- Cleaning: After each use, clean the picking units to remove any debris or leftover crop material. Use compressed air to clean the engine area and avoid dust buildup, which can impair engine performance.
- Checking the Harvesting Components: Regularly inspect the picking fingers, stalk rolls, and gathering chains for wear. Replace any worn parts to maintain efficient operation. Inspect the knife assembly and sharpening components for cuts that may result in inefficiency.
During the harvest season, check the machine before each use for any loose bolts, worn belts, or missing parts. Adjust the settings for crop type and field conditions to optimize performance.
- Storage: At the end of the season, clean the entire machine thoroughly. Store it in a dry, sheltered location to protect it from weather damage.
- Electrical System: Inspect the battery and electrical connections at least once a season. Clean any corrosion from terminals and ensure the battery is charged and in good condition.
Following these maintenance guidelines will help prolong the life of your John Deere 300 Corn Picker and ensure it runs efficiently during the harvest.
