This is the age of common platforms, yet AGCO sticks with the Gleaner transverse rotor design in its latest R6 Series. “This is the combine design concept that has defined the Gleaner brand for 30 years,” says Reid Hamre, communications manager for AGCO.
The R6 Series has two models. R66 has a 300-bushel grain tank and 300-horsepower AGCO 84CTA engine. R76 has a 330-bushel tank and a 350-horsepower version of the same engine.
Kevin Bien, AGCO product marketing manager for combines, says the company is “excited” about improvements to the “Natural Flow” transverse rotor combines for 2009. With the Natural Flow System, crop width never changes from the time it enters the feeder house opening to the time it enters the rotor. “This ribbon-like effect maximizes throughput capacity of our rotor,” Bien says. “And because we thresh the full circumference of the rotor, we are able to accomplish in one pass what it takes other axial rotors two passes to do, which maximizes efficiency, space and capacity.”
Over the past four years, AGCO has taken this Gleaner system and “super sized” it, Bien says. It started in 2006 with the Controlled Dynamic Flow (CDF) rotor for improved grain quality and reduced horsepower requirements. CDF is a solid core rotor 24 inches in diameter. It has six rows of cylinder bars and three rows of three knives on the separator side. “Crop spends less time in the rotor and processor area resulting in reduced horsepower requirements, better grain quality, less straw breakup, and better performance in green tough crop condition,” Bien says.
In 2007, Gleaner introduced a four-strand feed chain for reliable crop flow and increased the feed-chain speed for increased capacity. Then in 2008, Gleaner lowered the front feed floor to add more throughput area. “This alone has increased capacity dramatically,” Bien says.
NEW FEATURES FOR 2009
1. Diameter of the grain bin cross auger is increased to 12 inches so it can keep up to the 14-inch swivel auger. This two-auger system eliminates the vertical auger found in other three-auger turret systems. With this system, R6 combines unload at 4.0 bushels per second, which is the fastest available on any machine, the company claims.
2. The unload auger is three feet longer and the discharge end is 19 inches higher. This is to accommodate wider headers and larger trucks and carts.
3. The grain bin fill auger is 33 per cent larger — at 12 inches — to increase clean grain elevator capacity.
4. A new “cascade” grain pan increases shoe capacity. The cascade pan, which has ridges along the full width, controls grain coming off of the accelerator rolls so it drops more evenly onto the chaffer and sieve. The new pan has a six-degree pitch to improve capacity in high moisture crops and on hillsides, Bien says. You can also get an optional electric chaffer and sieve adjustment, which you work from the left side of machine or from the console in the cab.
5. More and better lights give you 100 feet more lumen projection than the competition, Bien says.
6. Inside the cab, you’ll find a new C2000 colour terminal with video capability. This screen can display images from up to two remote cameras installed anywhere on the combine. Bien says you could put one on the unloading tube so you can see into the grain truck and, when folded, to the rear of the combine. And you could put another in the grain tank. Another new cab feature is an optional heated vented leather seat.
THE GLEANER A6 SERIES
Remember what I said at the top about common platforms. While the R6 Series keeps with Gleaner tradition, the new A6 Series is a Massey Ferguson axial rotary decked out in Gleaner silver. As Bien says, the A6 Series models — A66, A76 and A86 — parallel the MF 9005 series. Grainews had an article on these MF combines in September.
