John Deere C670 Combine Parts
C670 parts and accessories
The John Deere C670 combine, manufactured from 2012-2016, provided farmers with a high-capacity harvesting solution. Boasting a powerful John Deere PowerTech 9.0L engine delivering 402 horsepower, it handled tough conditions with ease. Available with header widths ranging from 30 to 40 feet and utilizing an S-Series rotary separator, the C670 quickly gained popularity for its efficient grain processing and impressive throughput.
The John Deere C670 combine was introduced as part of the S-Series lineup, filling a crucial role in high-capacity harvesting. Produced from 2012 to 2016, this model was designed for farmers seeking increased productivity and efficiency. At its heart is a John Deere PowerTech 9.0L six-cylinder diesel engine, rated at 402 horsepower (296 kW). This engine provides ample power to handle demanding harvest conditions. The C670 utilizes an S-Series single rotor separator, featuring a tri-stream rotor design for efficient threshing and separating. The grain tank capacity is 300 bushels (10,600 liters), and the unloading auger boasts a rate of 3.3 bushels per second (116 bu/min). Header widths ranged from 30 to 40 feet, allowing for wide swaths and reduced field passes. Chopper and spreader options included fine-cut choppers and powered spreaders, ensuring proper residue management. The cab offered improved comfort and visibility, equipped with the GreenStar 3 CommandCenter display for precise machine monitoring and control. The C670 excels at harvesting a variety of crops, including wheat, corn, soybeans, and other small grains.

Maintenance Tips
- Concave Adjustment: Regularly check and adjust concave clearance based on crop type and moisture content. Proper concave setting ensures efficient threshing and minimizes grain loss.
- Belt and Chain Tension: Inspect belt and chain tension regularly, especially before and during harvest season. Loose belts and chains can lead to slippage, reduced performance, and premature wear.
- Sieve and Chaffer Cleaning: Keep sieves and chaffers clean to maintain optimal airflow and separation efficiency. Clean them regularly, especially when transitioning between different crops or if there's excessive material other than grain (MOG).
- Bearing Greasing: Follow the manufacturer's recommended greasing schedule for all bearings throughout the combine. Proper lubrication prevents premature bearing failure and extends the life of your machine.
