John Deere’s S Series Combines

05:55AM Aug 25, 2011

The John Deere S-Series Combines include five models: S550, S660, S670, S680 and S690, which is an all-new Class 9 machine. The 400-bushel grain tank (standard on S680 and S690) is the largest factory-available tank in the industry and can unload 3.8 bushels per second.

The cab of the new S-Series Combines has been completely redesigned from the ground up—this is the first new combine cab from John Deere since 1989. The larger cab environment, with 30% more interior space, also incorporates a window design that provides more visbility of the unloading auger. An integrated armrest display features touch-screen capability and AMS precision technology functionality. Changing gears is simple with electric push-button shift  and ProDrive transmissions.

An automated folding grain bin cover is optional.
The cleaning system has been redesigned with a newly engineered cleaning shoe which delivers 33 percent increased capacity. The Variable Stream rotor is a new option that improves straw quality in rice and high-yielding small grains with tough, dense straw.
A new Premium Residue Management system provides more uniform material distribution; windrow straw for a baling application while spreading chaff; and a wind compensation feature added to the PowerCast tailboard. The Active Tailings System (also standard on S680 and S690) increases threshing and separating capacity by 8% to 10% for improved grain and straw quality. It also has an updated Harvest Doc yield and moisture monitoring system.
