John Deere CTS Combine Parts
The John Deere CTS combine, produced from 1994 to 1996, was a popular choice for farmers seeking a high-capacity conventional combine. Its powerful engine, ranging from 225 to 255 HP, and ability to handle wide headers made it a productive machine in the field. The CTS stood out due to its innovative (for the time) walker design for efficient grain separation.
The John Deere CTS combine was introduced in 1994 and remained in production until 1996. This machine was designed to bridge the gap between conventional combines and the emerging rotary technology. Powering the CTS was a John Deere 6.8L diesel engine, producing between 225 and 255 horsepower, depending on the specific year and configuration. This engine provided ample power for threshing and propelling the machine through the field. The CTS features a conventional cylinder and walker design, with 6-row walkers for grain separation. Its grain tank capacity is approximately 220 bushels, allowing for extended harvesting without frequent unloading. The unloading auger boasts a rate of around 80 bu/min. The CTS could accommodate header widths ranging from 20 to 30 feet, making it suitable for various field sizes and crop types. Standard features included a comfortable cab with improved visibility and controls. The CTS proved particularly adept at harvesting wheat and soybeans, where its high-capacity threshing system could deliver excellent grain quality and minimal losses.

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 specific settings based on the crop being harvested.
- Belt and Chain Tension: Check belt and chain tension frequently, especially during the initial hours of operation. Loose belts and chains can lead to slippage, reduced performance, and premature wear.
- Sieve and Chaffer Cleaning: Clean sieves and chaffers regularly to prevent plugging and ensure efficient grain separation. Use compressed air to remove debris and inspect for damage.
- Bearing Greasing: Follow the recommended greasing schedule for all bearings. Proper lubrication is essential for extending bearing life and preventing costly breakdowns.
