John Deere made a big splash this past fall with the introduction of several new lines of machinery.

Leading the way was the new S-Series combine line.

Available for the 2012 harvest season, the S-Series Combines include five models: S550, S660, S670, S680 and S690, which is an all-new Class 9 machine. The S-Series Combines are ideal for producers and agricultural service providers who demand a combine that provides exceptional harvest power, grain-handling performance and field productivity.

To bring even more productivity to the S-Series Combines, 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 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 Active Tailings System (also standard on S680 and S690) increases threshing and separating capacity by 8 to 10 percent for improved grain and straw quality. It also has an updated Harvest Doc yield and moisture monitoring system.

The cab of the new S-Series Combines has been completely redesigned from the ground up for maximum comfort and visibility. The larger cab environment, with 30 percent more interior space, provides industry-leading visibility.

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.

And to help make the new S-Series Combines even more productive in the field, John Deere is introducing the new 600 Series Corn Heads, including the company's first 16- and 18-row heads, which are ideally matched for use with the new combines.

The 600 Series StalkMaster heads have row-unit chopping disconnects that allow the chopping feature to be disengaged on-the-go, as well as improved header height control, which senses farther forward and on outer rows.
