John Deere CTS-II Combine Parts
The John Deere CTS II combine harvester, manufactured from 1994 to 1997, offered farmers a blend of performance and reliability. Powered by a robust engine delivering significant horsepower, it handled a wide range of header widths. Its unique combine threshing system combines conventional and rotary technologies. This model gained popularity for its efficient grain separation and reduced grain loss compared to older conventional models.
The John Deere CTS II was produced from 1994 to 1997, filling a niche between traditional combines and the newer rotary models. It featured a Cummins 8.3L engine producing approximately 275 horsepower, providing ample power for demanding harvesting conditions. The CTS II utilized a unique hybrid separator system - an enhanced conventional cylinder for initial threshing followed by a pair of independent rotary separators for improved grain separation. Grain tank capacity was around 220 bushels, and it could unload at a rate of approximately 2.1 bushels per second or 126 bushels per minute. Available header widths ranged from 20 to 30 feet, accommodating various field sizes and crop types. It offered optional chopper and spreader attachments for residue management. The cab provided a comfortable operator environment, equipped with air conditioning and intuitive controls. The CTS II excelled in harvesting wheat, soybeans, and corn, due to its efficient threshing and separation system.
