Machinery Journal: Lean Harvesters Move Up a Class

In light of wet harvest conditions this fall, the three-model S8 Super Series of combines from Gleaner seeks to limit compaction concerns with a comparatively light combine pass. The machines feature increased engine-rated horsepower and maximum-boost horsepower enabled by dual-turbocharged engines. Those changes and others like it help define what the company calls its optimum harvesting performance platform.

"We’ve been busy increasing the capacity and the drives of the machine," says Kevin Bien, brand marketing manager for Gleaner.

At the heart of the S8 Series is the S88, the industry’s first Class 8 combine with a transverse rotor design. The machine offers a 9.8-liter seven-cylinder AGCO Power engine rated at 430 hp with twin turbochargers and weighs 16,500 lb. less than a competitive machine in the same class. It can move through the field requiring 32 hp less than competitive machines.

Also joining the S8 Series are the S78, a Class 7 combine, and the S68, a Class 6 combine. All are Tier 4 Final-compliant. The S78 features the same engine configuration as the S88, an upgrade from the 8.4-liter engine found in the S7 Series equivalent. It offers a 375-hp rating and maximum-boost horsepower of 451. Like the S88, the model operates using CEGR, diesel exhaust fluid and an engine speed of 2,100 rpm. S8 models operate without a diesel particulate filter.

The S68 offers an 8.4-liter, 322-hp engine rating and a maximum boost rating of 398 hp.

All combines in the series have fuel capacity of 230 gal., up from the 150 gal. available in S7 models. An optional XR transmission with two-speed hydro allows for better climbing on hills and on-the-go shifting with a 30% larger hydro pump.

A rugged two-speed DuraGuard rotor gearbox is better able to handle S8 horsepower increases with a larger belt and reversing capability. First with the S7 combines and continuing with the S8 machines, the diameter of the accelerator rolls has been increased by 25%.

Production begins in January. The price for the combine series ranges from $440,000 to $485,000, depending on the model and options. For more details, visit
