With the STS design, the diameter of the cage increases in the threshing section and even more so in the separation section. First, crop material expands, so grain trapped in the crop mat is freed. Second, the free-flowing material places less torque on the tine separator, so less horsepower is required to maintain separator speed. They provide excellent abrasion resistance and extra-long wear life. Tine separators, which work against bottom grates in the separation section, comb grain from residue.
Residue exits the separation section and is expelled by a beater out of the combine.
Grain drops onto Deere's new cleaning system, the DynaFlow, designed to match the STS's increased capacity. All rights reserved. Visit the home and family sites from our parent company.
