John Deere combines are available in two harvesting separator configurations: T670 (tangential-tine separator) and S-Series (single-tine separator) Combines.

The S-Series Combines provide customers with unprecedented rotary threshing and separating performance and capacity in all crops and conditions. The unique single-tine separator and exclusive TriStream™ crop-flow design provide superior material-handling performance in all conditions and higher levels of crop-harvesting capacity, as well as excellent grain quality. Five models ranging from Class V through Class IX capacity size are available to match customers' individual harvesting needs:

S550 Class V size                          S660 Class VI size

S670 Class VII size          S680 Class VIII size

S690 Class IX size

The T670 provides customers with unprecedented high-quality straw residue while delivering the highest productivity capable of a walker combine. The T670 is sized to deliver Class VII size combine capacity specifically geared to small-grain harvesting.

All John Deere Combines have built-in performance, safety, service, and reliability features to make harvesting easier and more profitable for the customer.

John Deere header equipment is specifically designed to utilize the capacity of the T670 and S-Series Combines, and provide customers with the best in header crop gathering and feeding performance.
