What the S680 is used for
The S680 was designed for large-acreage maize, soybean, wheat, and small-grain operations that need sustained output with wide headers. Its rotary system, large cleaning capacity, and 400-bushel tank target high-yield conditions and efficient grain-cart logistics.
It remains a sought-after used machine for larger farms and custom operators who can support its technology and operating scale. It is especially attractive when paired with a well-maintained draper or 12-row maize head.
Why the John Deere S680 stands out
The S680 is notable for bringing Deere's S-Series cab, electronics, cleaning system, and high-capacity grain handling to a widely used Class 8 machine. Its 400-bushel tank and strong engine output make it a substantial step up from earlier STS machines, while dealer support and header compatibility remain major advantages.
Buying a used John Deere S680
Review diagnostic history and calibration records, then inspect rotor and concave wear, feederhouse chain and floor, variable-speed or multi-speed feederhouse drive, cleaning shoe, chopper, grain-tank augers, unloading system, and final drives. Confirm emissions-system service, ProDrive performance, software and display operation, and both engine and separator hours; specifications and equipment vary by model year, so verify with Deere records.
