It's been 90 years since the Baldwin brothers built the first Gleaner harvester near Nickerson, Kan. On Aug. 15, over 1,500 people gathered at Wichita's Hartman Arena for Gleaner's launch of its Tier 4 Final Class 6 through 8 platforms and the first Class 8 transverse rotary combine in the industry.
Kevin Bien, Gleaner brand marketing manager, says 90 years of innovation have led directly to the new combines, which stay true to the original Gleaner ideals of durability, simplicity, and grain quality.
Class 8 combines are defined by their horsepower. The S88 and S78 have new Tier 4 Final engines – AGCO Power 9.8 liter 7 cylinder engines with dual turbochargers. The S88 is rated at 430 horsepower with a maximum boost of 471 horsepower, and the S78 at 375 horsepower with a maximum boost to 451 horsepower.
The S68 keeps its 8.4 liter, which has also been updated with dual turbochargers. It is rated at 322 horsepower with a maximum boost to 390 horsepower.
"It's a pretty exciting thing, because when you go to Tier 4 Final, you wouldn't expect that your fuel consumption numbers would actually drop," Bien says. "But we actually improved our torque and fuel consumption by going to the twin turbochargers on the engines that we have in all three models."
The engines meet Tier 4 emissions standards without using a heat-generating diesel particulate filter, or DPF, which is often used to remove diesel particulate matter. The new Gleaners avoid this by using selective catalytic reduction, or SCR, and external-cooled exhausted gas recirculation.
Improving grain quality and throughput capacity
Upgrading the Super Series actually started three years ago with its launch. With the industry's only transverse rotor, the 2011 model year had a huge processing capacity, increasing the volume by 48% with 360 degrees of separating area.
Grain spends less time in the separator, meaning improved grain quality – one of Gleaner's key traits. "The processor was already there," Bien says. "So what we started to do then is start looking at those areas that we would have to upgrade when we'd bump the horsepower up."
Gleaner engineers went through every drive of the machine to find areas that could be improved for the Optimum Harvesting Performance platform. One new feature is the new Dura-Guard two-speed rotor gearbox. The gearbox can reverse, making it easier to remove any foreign material plugging the rotor. It is designed to accommodate the needs of the Class 8 and changing harvesting dynamics of today and the future, with more grain going through the machine. It can also be found on the new Class 6 and 7.
