John Deere 9880-STS Combine Parts
9880 STS parts and accessories
The John Deere 9880 STS combine, produced from 2003-2006, offered farmers a powerful harvesting solution with its approximately 375 HP engine. Known for its innovative Single Tine Separator (STS) rotary system, it delivered efficient grain separation across various crops. Available header widths ranged significantly, making it a versatile choice for diverse field conditions and farming operations.
The John Deere 9880 STS was a significant step in combine technology, manufactured between 2003 and 2006. Powering this machine was a John Deere 9.0L PowerTech engine, delivering around 375 horsepower with a displacement of 549 cubic inches. The standout feature was its Single Tine Separator (STS) rotary system, which provided enhanced threshing and separation capabilities compared to conventional cylinder combines. The grain tank held approximately 300 bushels, and unloading was quick, thanks to an unloading auger rate of around 3.0 bushels per second (180 bu/min). It could accommodate a range of header widths, from 20 to 36 feet, catering to different row spacings and field sizes. Optional features included a fine-cut chopper and adjustable spreaders for residue management. The cab was designed for operator comfort, featuring air conditioning, adjustable seating, and intuitive controls. The 9880 STS excelled in harvesting corn, soybeans, wheat, and other small grains, providing high throughput and reduced grain loss.

Maintenance Tips
- Concave Adjustment: Regularly inspect and adjust concave clearance based on the crop being harvested to optimize threshing and minimize grain damage.
- Belt and Chain Tension: Check and maintain proper tension on all belts and chains to prevent slippage and ensure efficient power transmission.
- Sieve and Chaffer Cleaning: Regularly clean sieves and chaffers to prevent plugging and maintain optimal cleaning performance, especially when transitioning between crops.
- Bearing Greasing: Follow the recommended greasing schedule for all bearings to prevent premature wear and failure. Pay close attention to the bearings in the header, separator, and unloading auger.
