John Deere 9880I-STS Combine Parts

9880I STS parts and accessories

The John Deere 9880I STS combine, produced from 2003-2006, offered farmers a powerful and efficient harvesting solution. Powered by a robust engine producing over 375 HP, it was available with header widths ranging up to 36 feet, making it suitable for large-scale operations. The Single Tine Separator (STS) rotary system quickly made this model popular for its high throughput and reduced grain loss when harvesting various crops.

The John Deere 9880I STS was a significant combine in the early 2000s, manufactured from 2003 to 2006. It was equipped with a John Deere PowerTech 9.0L six-cylinder diesel engine, delivering approximately 375 horsepower (depending on model year and specifications). The 9.0L engine provided ample power for the combine's demanding tasks. A key feature of the 9880I STS was its Single Tine Separator (STS) rotary system, which provided improved threshing and separation compared to conventional cylinder combines, leading to less grain loss and higher quality grain samples. Its grain tank capacity was 300 bushels, and the unloading auger could empty the tank at a rate of approximately 3.0 bushels per second (180 bu/min). Available header widths ranged from 25 to 36 feet, allowing for efficient harvesting across various field sizes. The combine offered options for chopper and spreader configurations, effectively managing crop residue. The cab provided a comfortable and technologically advanced operating environment, enhancing operator efficiency and reducing fatigue. The 9880I STS excelled in harvesting corn, soybeans, wheat, and other small grains, establishing a reputation for reliable performance and high capacity.

Maintenance Tips

Concave Adjustments: Regularly check and adjust concave clearance based on crop type and moisture content to optimize threshing performance and minimize grain damage.
Belt and Chain Tension: Inspect and maintain proper tension on all belts and chains to prevent slippage, excessive wear, and potential breakdowns during harvesting.
Sieve and Chaffer Cleaning: Regularly clean sieves and chaffers to remove debris and ensure proper airflow, maximizing grain separation and minimizing losses.
Bearing Greasing: Follow the recommended greasing schedule for all bearings, especially those in high-stress areas such as the header, feederhouse, and separator, to prevent premature wear and failure.

History & Background
