John Deere W660 Combine Parts
W660 parts and accessories
The John Deere W660 combine, produced from approximately 2010-2016, offered a blend of performance and reliability for grain harvesting. With engine horsepower in the range of 370 HP, and available header widths up to 36 feet, it was a versatile machine. Farmers appreciated the W660 for its high capacity conventional separator system and efficient grain handling.
The John Deere W660 combine was introduced to offer a high-capacity harvesting solution using a conventional threshing and separation system. Production years were approximately 2010 to 2016. The W660 is powered by a John Deere PowerTech 9.0L 6-cylinder diesel engine, producing around 370 horsepower. It utilizes a conventional threshing system with a wide cylinder and large walker area to efficiently separate grain from straw. The grain tank capacity is approximately 300 bushels, with an unloading auger capable of unloading at a rate of around 3.3 bushels per second (200 bu/min). Available header widths ranged up to 36 feet, allowing for high harvesting capacity in various crops. Options included a fine cut chopper and adjustable spreaders for residue management. The cab offered comfort and technology, including advanced monitoring systems and controls for optimizing harvesting performance. The W660 excels in harvesting crops like wheat, barley, and soybeans where a thorough threshing action is required but where a conventional separation system provides adequate capacity and gentle grain handling.

Maintenance Tips
- Concave Adjustment: Regularly inspect and adjust concave clearance according to the crop being harvested. Proper clearance ensures efficient threshing and minimizes grain loss.
- Belt and Chain Tension: Check and maintain proper tension on all belts and chains, especially the feeder house and threshing drive components. Loose belts and chains can lead to slippage and reduced performance.
- Sieve and Chaffer Cleaning: Clean the sieves and chaffer screens frequently to remove debris and ensure proper air flow. Clogged screens can result in grain loss and reduced cleaning efficiency.
- Bearing Greasing: Grease all bearings according to the manufacturer's recommendations. Proper lubrication is crucial for preventing premature wear and extending the lifespan of critical components.
