The Complete Guide to John Deere Implement Setup and Maintenance

John Deere implements have been working the soil for generations. From moldboard plows that turn the first furrow in spring to disk harrows that finish the seedbed, proper setup and maintenance are essential for optimal performance and longevity. This guide covers the essential information for working with John Deere tillage equipment.

Moldboard Plow Setup and Adjustment

Proper plow adjustment is critical for even tillage and proper soil inversion:

• Hitch Adjustment: Set the hitch height and level to ensure the plow runs level front-to-back and side-to-side. Incorrect hitch adjustment causes uneven plowing depth.
• Fore-and-Aft Leveling: Adjust the top link so the plow runs level from front to rear. The rear bottom should run at the same depth as the front.
• Side-to-Side Leveling: Adjust lift linkage so the plow is level side-to-side. Use the leveling crank on most John Deere plows.
• Couller Adjustment: Set coulters to run just ahead of the share. Depth should be 1-2 inches less than plowing depth in most conditions.
• Landside Clearance: Check landside clearance and adjust as specified in the manual.

Disk Harrow Adjustment

• Disk Angle: Adjust gang angle for desired penetration and soil mixing. More angle for deeper penetration, less for lighter tillage.
• Disk Scrapers: Adjust scrapers to keep disks clean. Proper adjustment prevents soil buildup and improves penetration.
• Leveling: Adjust hitch and lift linkage so the harrow runs level. Check front-to-rear and side-to-side level.
• Transport Position: Ensure lock pins are properly engaged before transport.

Fertilizer Attachment Service

• Meter Calibration: Calibrate fertilizer meters according to manual instructions. Check calibration annually or when switching materials.
• Drive Chains: Inspect and lubricate drive chains regularly. Adjust tension per manual specifications.
• Openers and Boots: Check opener wear and adjust depth. Inspect tubes for wear and replace if damaged.
• Clean-Out: Thoroughly clean fertilizer attachments after each use to prevent corrosion.

Common Implement Problems and Solutions

• Uneven Tillage Depth: Check hitch leveling, tire pressure, and implement leveling. Adjust as needed.
• Poor Soil Penetration: Add weight, adjust disk angle, or check for worn parts. Sharp shares and disks are essential.
• Implement Not Level: Adjust hitch height and lift linkage. Check tire pressure on the tractor.
• Transport Problems: Verify lock pins are engaged. Check for proper clearance and lighting.
• Parts Wear: Inspect shares, disks, sweeps, and points regularly. Replace when worn to maintain performance.
