It also has the fastest unloading rate in the industry at 4 bushels a second. "The two-auger unloader system has a cross auger in the grain tank, and when it transitions to the unloader, it's a shallow 29-degree angle. So there's not three augers with 90-degree angles found on turret systems," Bien explains.
This means less wear, better grain quality, and less horsepower needed. "Anytime you have a 90-degree angle, imagine the amount of horsepower it takes to move that grain," he says.
More horsepower where it counts
A key Gleaner feature is a lighter weight, even with its 390-bushel grain bin. Gleaner's Natural Flow system, which moves the crop from feeding to threshing in a "smooth ribbon" without changing direction, allows a more compact, lightweight combine.
"The S88 touts itself as a 15,600-pound lighter combine than one of our leading competitors out there," Bien says. "That translates to about 31 horsepower that you save with the Gleaner. That savings goes directly to the separator."
Another horsepower-saving feature is the new SmartCooling system, which uses a reversing variable-pitch fan. It monitors air intake temperature, coolant temperature, hydraulic oil temperature and outside ambient temperature, and adjusts pitch accordingly.
Every 15 minutes for 5 seconds, it automatically reverses the air and blows out the radiator, cooler, and rotary screen, and tilts back to a 40-degree pitch and cleans the engine compartment. It cleans and cools with up to 66% less horsepower.
"We can avoid doing the one thing that most customers just hate: having to get an air compressor out, having to clean your radiator out because you've got a lot of soybean fuzz or you've got chaff and debris in the radiator," Bien says. "[The operator] always knows he never has a plugged radiator, or any coolers, he never has to worry about a heat buildup because the radiator's plugged. It's piece of mind that he has."
Reducing these factors, or parasitics, contributes to more horsepower going to the separator, a key Gleaner feature and focus of the new combines.
"Up to 88% of the rated horsepower is getting to that main clutch shaft," Bien says of the S88. "When the customer is in the field, he's also going to see a higher horsepower utilization to the separator due to lower weight and more efficient drives."
