Maintenance and Troubleshooting Tips for the John Deere 640 Hay Rake

Regularly Inspect the Tines: Check the tines for any signs of wear or damage. Replace any tines that are bent, broken, or excessively worn to ensure optimal raking performance. Use only genuine John Deere parts for replacements to maintain the rake’s efficiency.

Hydraulic System Care: Keep the hydraulic system clean and well-lubricated. Inspect hoses for leaks or cracks and replace them as needed. Regularly check fluid levels and replace the hydraulic oil every 200-250 hours of operation to prevent system failures.

Drive Components Maintenance: Inspect the drive chain, bearings, and sprockets frequently. Tighten or replace components showing signs of wear. Lubricate the bearings regularly to reduce friction and prolong the life of these parts.

Adjusting the Raking Angle: If the hay rake is leaving clumps or spreading unevenly, adjust the raking angle. A simple turn of the angle adjustment lever can fix the issue. Always ensure that the rake is set at the proper angle to match the field conditions.

Check the Wheels and Tires: Ensure that the wheels are properly inflated and free from debris. If the tires show uneven wear, it may be a sign that the rake is out of alignment or the weight distribution is off. Regularly check for damage and replace tires as necessary.

Common Troubleshooting Issues:

• Rake not turning: If the rake isn’t turning, check the drive belt for tension or wear. Replace any damaged belts.
• Uneven raking: This could be caused by improper tine adjustment, worn bearings, or incorrect rake angle. Ensure that all components are aligned and functioning properly.
• Hydraulic issues: If the hydraulic system isn’t functioning as expected, check the fluid levels, filter, and hoses. Clogged filters or low fluid levels are common culprits.

Storage and Off-Season Care: Before storing the John Deere 640 hay rake for the off-season, clean it thoroughly to remove any dirt, grass, or debris. Store it in a dry, sheltered area to prevent rust and corrosion. Grease all moving parts and ensure the rake is fully functional before the next use.
