| The next revolution: STS bullet rotor technology |

In 1999, John Deere revolutionized combine harvesting with the Single Tine- Separation (STS) system.
For 2006, John Deere is introducing the STS Bullet Rotor, which uses a tapered, bullet-shaped front end and threshing elements to reduce rotor load and engine power requirements, and to improve the efficiency of the entire threshing and separating system.
“What we’re doing is reducing the force it takes to move crop through the combine,” says Chris Savener, senior sales and service representative, John Deere Harvester Works. “By doing that, we’ve decreased the amount of engine power required to drive the rotor by as much as 20 percent in tough small grains conditions.”
But the benefits aren’t limited to wheat, rice or other grain crops.
“Faster ground speed is possible in tough, green-stem soybeans as well,” says Savener. “And no matter what crop you’re harvesting, the combine operates more comfortably and more efficiently.”
High-powered tailboard option
Significant changes have been made to the residue management system of the 60 Series STS Combines as well. The PowerCast Straw Chopper Tailboard gives operators a thin, consistent residue layer, with a spread width from 35 to 50 feet … adjustable on the go, from the cab.
“The PowerCast tailboard is an optional feature we wanted to make available for growers who use wide headers, or who typically harvest crops in windrows,” says Savener. “The PowerCast tailboard should be very beneficial for out no-till customers as well.”
Also for 2006
Other features and options available on the 2006 60 Series Combines include:
High-torque variable drive feederhouse
Designed especially for use with large corn heads, the feederhouse uses larger cams, pulleys, drive belts, and springs to give a 20 percent increase in capacity, increased cooling ability, and extended belt life. Available on corn-configured 9760 STS and 9860 STS, optional on small grain- and rice-configured 9660 STS, 9760 STS, and 9860 STS.
Engine air scoop
Engine-area bodywork has been fitted with a scoop which pulls clean air from above the clouds of dust and residue, reducing the load on air cleaning components and increasing working room around the engine. Standard on 9660 STS, 9760 STS, 9860 STS.
StalkMaster Corn Head Chopping System
The StalkMaster system uses knives mounted beneath row units to chop and size stalks while harvesting, eliminating the need for second-pass chopping and saving fuel, labor, and operating costs. Knives can be easily removed if chopping isn’t needed. Optional on 8row30 and 12row22 John Deere 90 Series Corn Heads.
Folding auger
Growers who put a lot of road miles on their combines will appreciate the folding unloading auger, which folds around the back of the combine, dramatically reducing the total length of the machine. Optional on 9660 STS, 9760 STS, and 9860 STS.
