More efficient unloading, better grain quality
The unique DirectFlow™ swivel unloader on all Gleaner S7 Series accomplishes the marvel of an average unloading speed of 4 bushels per second throughout the entire unloading process with a larger 12-inch (305 mm) grain bin cross auger that feeds a massive 14-inch (356 mm) unloader auger. This DirectFlow two-auger design is the basis for our S7 Series unloading system.
Because we only use two augers rather than three, like our competition, Gleaner provides more efficient unloading with better grain quality and less wear. No gearboxes. No open drives. No vertical augers.
With the transition angle between the grain bin cross auger and swivel auger reduced, it means less horsepower and reduced fuel consumption to achieve this impressive unloading rate.
The unloading auger provides a 15-foot (4.54 m) discharge height and a 23-foot (6.98 m) reach from center.
On the S67, with its massive 330-bushel (11,629 L) grain tank, the unloading time is 75 seconds. The S77 unloads its optional 390-bushel tank (13,743 L), with the largest Class VII standard bin capacity, in 83 seconds. The optional 390-bushel grain tank with foldable bin extension unloads in 98 seconds.
