John Deere 9650STS Combine Parts
9650STS parts and accessories
The John Deere 9650STS combine, manufactured from 1999 to 2002, offered farmers a powerful and efficient harvesting solution. Boasting around 300 engine horsepower and compatibility with a range of header widths, this rotary combine became popular due to its ability to handle high volumes of grain and improve harvesting efficiency.
The John Deere 9650STS was introduced in 1999 as part of the STS (Single Tine Separator) series, marking a significant advancement in rotary combine technology. Its engine, a John Deere 8.1L 6-cylinder diesel, delivered approximately 300 horsepower, providing ample power for demanding harvesting conditions. The heart of the 9650STS was its rotary separator, featuring a single tine rotor design known for its improved grain quality and reduced grain loss compared to conventional cylinder combines. The grain tank held around 225 bushels, and the unloading auger could discharge grain at a rate of approximately 2.5 bushels per second (150 bu/min). Available header widths varied depending on the crop and terrain, ranging from 20 to 30 feet for grain platforms and 6-8 row corn heads. Chopper and spreader options were available to manage crop residue effectively. The cab provided operators with a comfortable and ergonomic workspace. The 9650STS proved to be particularly adept at harvesting crops like corn, soybeans, and wheat, where its rotary system minimized grain damage and maximized throughput.

Maintenance Tips
- Concave Adjustment: Regularly inspect and adjust concave clearance to ensure optimal threshing and minimize grain damage. Refer to the operator's manual for recommended settings based on crop type.
- Belt and Chain Tension: Check and maintain proper tension on all belts and chains. Loose belts and chains can lead to slippage, reduced performance, and premature wear.
- Sieve and Chaffer Cleaning: Regularly clean the sieves and chaffer to remove debris and ensure proper airflow for efficient grain separation. Clogged sieves can result in grain loss.
- Bearing Greasing: Grease all bearings according to the manufacturer's recommended schedule. Proper lubrication is crucial for preventing bearing failure and extending the lifespan of your combine.
