John Deere 9650CTS Combine Parts
The John Deere 9650CTS combine, manufactured from 1999-2001, offered farmers a powerful solution for grain harvesting. Boasting around 275 engine HP and available with header widths up to 30 feet, the 9650CTS featured a unique Twin Separator system. Its robust design and high throughput capacity made it a popular choice for handling a variety of crops, increasing harvest efficiency for farms of all sizes.
The John Deere 9650CTS was introduced in 1999 and remained in production until 2001. It was part of John Deere's CTS (Combine Twin Separator) series, known for its unique threshing and separation system. Powering the 9650CTS was a John Deere 8.1L 6-cylinder diesel engine producing approximately 275 horsepower. This engine provided ample power for demanding harvesting conditions. The 9650CTS utilized a Twin Separator system, featuring a conventional cylinder for initial threshing followed by two rotary separators for enhanced grain separation. This system improved grain quality and reduced losses compared to traditional combines. The grain tank capacity was around 220 bushels, and the unloading auger could unload at a rate of approximately 2.1 bushels per second (126 bu/min). Available header widths ranged from 20 to 30 feet, allowing for efficient harvesting of various crop types. Chopper and spreader options were available to manage crop residue effectively. The combine's cab offered operators a comfortable and functional workspace, enhancing productivity during long harvest days. The 9650CTS excelled in harvesting crops like wheat, corn, and soybeans, delivering reliable performance and efficient grain separation.

Maintenance Tips
- Concave Adjustment: Regularly check and adjust the concave clearance to optimize threshing performance and minimize grain damage. Refer to the operator's manual for specific settings based on crop type and conditions.
- Belt and Chain Tension: Inspect and maintain proper tension on all belts and chains, especially the feederhouse chain, separator drive belt, and unloading auger chain. Loose or worn belts and chains can lead to reduced performance and premature wear.
- Sieve and Chaffer Cleaning: Regularly clean the sieves and chaffer to prevent buildup of crop residue, which can hinder grain separation and increase grain loss. Use compressed air or a brush to remove debris.
- Bearing Greasing: Follow the recommended greasing schedule for all bearings throughout the combine. Proper lubrication is essential for preventing bearing failure and extending component life.
