Get the best of both worlds: tremendous capacity and superb grain quality
It may look like a conventional rotary, but it’s not. It’s more. Thanks to tine separation, a new Hi-Performance rotor design, and other John Deere innovations, the 9880 i STS overcomes many of the limitations often associated with rotary machines.
You get the overwhelming capacity you are looking for without sacrificing grain quality. You get better material flow and longer straw with considerably lower power requirements than conventional rotary designs.
The Intelligent Advantages.
-
Exclusive Hi-Performance rotor design gives increased capacity and longer straw.
-
Exclusive tine separation delivers outstanding capacity and grain quality
-
Tine separation pull-and-release action reduces horsepower requirements, handles all crops, all conditions
Crop flows from the feed accelerator directly to the specially designed STS module.
John Deere tri-stream feeding
Rather than pushing the crop mat into the separator module in one large clump (right) – a prime cause of slug feeding and crop roping – the John Deere design flows crop into the module in three streams. This provides more uniform material flow, especially in high moisture or high yielding crop and green conditions.
The 9880i STS features our new High Performance Rotor for improved performance in a variety of crops. This rotor design can reduce rotor power requirements by up to 20 percent, increase
separator capacity up to 10 percent, and give you longer straw that’s easier to bale. You’ll also get better performance from the cleaning system, as well as reduced cage and rotor wear.
The 9880i STS combine’s stepped module allows the crop mat to expand as it moves through the separator. Its tine-combing action, combined with pull-and- release expansion, helps free grain trapped in the crop mat, resulting in significant grain savings and efficient use of horsepower.
Six rows of tines are angled to aggressively comb and penetrate the crop mat, freeing any remaining grain. You’ll put more grain in the tank.
A 5 wing discharge beater quickly sweeps crop material away from the rear of the STS module.
