Gleaning more from every harvest

In addition to updates to the A6 axial rotor Gleaners, the transverse rotor Models R66 and R76 (shown) also gained multiple updates including a new cab with a more powerful lighting package to help operators handle nighttime harvest operations.

From the first methods of harvesting by hand, to the affordable machinery that allowed larger areas to belong to one farm, to the massive technology-filled combines of today, the combine harvester has evolved to a state-of-the-art workhorse. In a period where efficiency and costs are primary sales tools, Gleaner has introduced two new R6 and three new A6 models designed to be faster, more comfortable, and most importantly, more productive.

The AGCO 84CTA inline six-cylinder diesel engine delivers 300 hp (224 kW) for the Gleaner R66 and 350 hp (261 kW) for the Gleaner R76 at 2100 rpm. When the engine rpm is pulled down to 1900 rpm, a power bulge of 321 and 375 hp (239 and 280 kW) is available. It comes with Bosch common rail fuel injection and the EEM3 electronic engine management systems for improved efficiency.

Model A86 uses a C13 engine that delivers 425 hp (317 kW) with a bulge to 459 hp (342 kW), and all are turbocharged and intercooled. Power is fed through a high-torque, four-speed transmission that is located directly behind the front axle beam to protect the transmission from field damage. The heavy-duty, hydraulically activated drum brakes are located inboard of the final drive assemblies.

Operators have improved interior and exterior lighting as well as a new control system that stores up to 20 crop settings. For improved accuracy, satellite-guided steering systems allow fewer overlaps during harvesting.

The redesign of the models continues in the feeding and processing areas, where improved floor design and enlarged holding bins allow good capacity. Gleaner claims the new combines are simpler than other competitors' models, with 52% fewer drive belts and 62% fewer drive chains due to a transverse rotary setup. This does not affect performance though, as the A66 and A76 models are standard with 300 bushel bins that can unload in only 75 s. The 350 bushel bin standard on the A86 (optional on the A76) can be unloaded in only 88 s.
