Two-stage, four-strand gathering chain system. This allows the cylinder to be smoothly fed at the same angle regardless of the header height. Long feeder house with lowered rear feed floor providing an increase of 65 in² (420 cm²) to allow a smooth and higher flow of material.

The Natural Flow™ transverse rotor in our Tritura processor keeps crop moving in one uninterrupted direction directly from the header, into the rotor and out the rear of the machine.

Distribution augers to spread material evenly before it enters the cleaning process, allowing a uniform ribbon of material without the uneven feeding and bunching of other designs.

Accelerator rolls that speed the crop's descent, allowing more air to clean the crop more thoroughly with reduced sensitivity to hills and slopes without the expense and complexity of self-leveling cleaning systems.

Transverse fan with exclusive two-stage cleaning. The first stage cleans heavy material right beneath the accelerator rolls, pushing chaff out the rear of the combine. The second stage comes up through the sieve and chaffer, lifting remaining chaff and carrying it out the rear of the combine. This greatly improves cleaning efficiency over competitive designs.

Fully welded frame keeps the S7 Series solid, strong and provides a stable foundation for all shafts and components.

Low center of gravity, heavy final drives and welded frames on the S7 Series provide for large bin capacities of 300 bushels (10,570 L) on the S67 and 330 bushels (11,629 L) on the S77, which is the largest standard bin capacity in the industry. Optional 390 (13,743 L) bushel bin capacity on both models is the largest optional bin capacity available on any combine.

Unique "Direct Flow" two-auger design features a large 12” (305 mm) grain bin cross auger that feeds the 14” (356 mm) swivel unloader auger. Because we use only two augers versus 90-degree turns of competitive three or more auger turret systems, you deliver better grain quality with less component wear, combined with reduced horsepower and fuel requirements.

Painted galvanized exterior panels prevent rust, corrosion, expensive repairs and static electricity build-up associated with steel or plastic designs.
