Also question is, what is a rotor on a combine?
The rotary combine uses centrifugal force to drive the grain through the straw. The faster the cylinder spins, the higher the centrifugal force so it's easy to increase the capacity. The limit to how fast the separation rotor can be turned is controlled by whether the operator is cracking the grain.
Furthermore, what does STS mean on John Deere combine? Single Tine Separator
In respect to this, what class is a 9770 John Deere?
The 9770 is probably the best combine John Deere has made especially the 2010 and 2011. It is very well balanced in power and capacity and is closer to a class 8 than a class 7. It is also good on fuel compared to a 9870 or a S680. Most guys that went from a 9770 to a S680 got 10% more capacity and 50% more fuel usage.
How does a combine work?
The Anatomy of a Combine The cut crops move toward the center via spinning augers and travel up a conveyor. The threshing segment of the combine beats the cut crops to break and shake the grains away from their stalks. When the grain tank is full, a tractor with a grain cart on the back pulls alongside the combine.

When harvesting crops, a combine harvester can be extremely helpful. The cutter bar then cuts the crops down, which leads to a revolving reel—which gathers these cut crops. These cut crops are them pushed into the threshing area, which very quickly separates the grains from the stalks.What is a walker combine?
“This is the only straw walker combine to offer an accelerator drum to balance crop flow and to optimize capacity of the threshing cylinder,†he points out. “The crop feeds more evenly into the threshing cylinder, even in wet harvest conditions, and produces higher centrifugal force for more effective separation.â€What year did John Deere come out with a rotary combine?
