This system is entirely carried over to the new models; however, power on the six redesigned and revamped models varies from 265 hp (198 kW) and 250-bushel capacity to 483 hp (360 kW) and 350-bushel capacity.
The 5088 and 6088 (replacing the 2577 and 2588, respectively) models are powered by an 8.3-L Cummins engine while the brand new 7088 sports a 9.0-L Cummins engine. The company's first Class IX combine, the 9120, is powered by the 12.9-L Cursor 13 diesel. Rounding out the 2009 combine lineup are the 7120 (replacing the 7010) and the 8120 (replacing the 8010).
Case's 9120 "is for larger operators looking for high-end productivity features like CVT drives and rotor-reversing, combined with Axial-Flow single-rotor combine technology," said Leo Bose, Case IH Combine Marketing Manager. "Fewer moving parts, fewer belts, gentle grain-on-grain threshing, more grain savings, matched capacity—all the Axial-Flow core principles from more than 30 years ago are still here, just on a larger scale."
Axial-Flow combines are available with a variety of tire options, "and we've just added another one," said Bose. "The 8120 and 9120 models can be equipped with the Quadtrac track system on the front axle for greater flotation and less soil compaction."
Quadtrac uses two 36 in (914 mm) wide rubber tracks, which reduce ground pressure by 50 to 60% compared to dual-drive tires, says Case.
Productivity has never been more important than now, and Case has increased power across the board to allow for more harvesting in less time. The self-leveling cleaning sieves now stay level on slopes of up to 14%, reducing waste. Cutting heads for up to 12 rows of corn are available, and the Case MagnaCut straw chopper has 126 blades for finely dicing residual wastes.
Styling of combines has never been a selling point, but Case has taken steps to make the bodies of the new models more practical. A low trim panel at the rear helps to keep dust levels down and residues from accumulating. In an effort to use products from the fields in which Case models work, two of the side access panels are made of soybean-based products.
The 88 series has also been lengthened and given a wider front axle. This allows a better weight distribution of 60-40 as well as the elimination of previously needed weights on the rear when using a wider header.
The headers themselves are now interchangeable among both the 20 and 88 series models, a plus for farms with more than one harvester.
