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.
