Case IH: All-new combine line-up for 2009

The 2009 Case IH combine offering has been completely revised and now features six models. The new Axial-Flow 20 Series consists of the 7120 (maximum power 422hp), 8120 (469hp) and the 9120 (530hp), while the Axial-Flow 88 Series includes the 5088 (294hp), 6088 (335hp) and the 7088 (366hp).
The 5088, 6088, 7120 and 8120 all offer more horsepower than the models they replace. The 7088 is a brand new addition to the range, while the 9120 offers the same power output and performance as the Axial-Flow 9010 that was launched last year.
Engines apart, both the Axial-Flow 20 Series and 88 Series introduce new design characteristics to make these new combines easier to live with. One of the most noticeable features, which spans both the mid-range and flagship machines, is a new maintenance platform to the rear of the combine that gives easy access to all engine components. A built-in ladder, that can be pulled down to ground level, makes climbing up to the top of the combine both safe and convenient.
The combines also feature new, high-quality plastic side panels, made from renewable raw materials, that reduce operational weight and ensure a longer service life, but it’s under the skin that the most important changes have been made. At the heart of the machines, for example, is the latest Small Tube Axial-Flow rotor developed by Case IH, which will be fitted as standard on all UK-specification 88 Series and 20 Series combines.
The result of more than 30 years of continuous development, thSmall Tube rotor is more streamlined and compact than before, offering many advantages in the field. Compared to previous rotors it has a smaller diameter, increasing the space between the rotor and the concaves to allow more material to flow through.
The crop is now handled even more carefully and the quality of the straw has been improved without compromising on the proven Axial-Flow advantages of simplicity, versatility, capacity and grain quality.
In operation, the new rotor also results in reduced fuel consumption, despite the increase in performance and throughput. The use of advanced materials in the rotor head, intake and vanes and higher-strength rotor drive components, meanwhile, extend the service life and increase the reliability of the rotor system.
The settings for the new Small Tube Axial-Flow rotor can be adjusted to varying harvest conditions and crops at the touch of a button in the cab. The rotor speed can be precisely controlled between 220-1,200rpm, while sieve clearance and threshing gap are controlled automatically depending on the crop type selected. Due to the lightweight threshing and separation concaves, which are easily accessible and easy to change, these combines are suitable for every kind of threshable crop.
The Axial-Flow 20 Series now features a new, high-capacity feeder and a redesigned high-throughput transition cone. The conveyor chains are now spring-loaded, which ensures that the crop passes smoothly from the header into the rotor intake, where it is gradually accelerated up to threshing speed. This is said to offer increased durability over the previous design.
Also new on the 20 Series is an innovative high-performance chopping system equipped with 126 fixed blades (8120 and 9120), which ensures impressive chopping quality even at high straw flow rates. The 7120 combine is equipped with a modified chopping system with 63 fixed blades.
The entire design of the chopping system and the way it works has been revised; more power is now available resulting in much better chopping quality and residue distribution. A new guide plate improves straw flow and its angle can be electronically controlled from the cab. The working width of the chopping system can also be adjusted from the cab to allow for cross winds.
In windrowing mode the counter-knives in the chopping system are retracted so that the blades on the chopping drum acts as paddles to guide the straw out the back of the combine and help achieve an ideal swath shape.
All 20 Series models are now equipped with a 10,500-litre grain tank and a high-speed unloading auger that empties at 113 lit/second, meaning that it takes less than 95 seconds to empty the grain tank. A 5.5m unloading tube is standard with an optional 6.5m version also available.
The Axial-Flow 20 Series can be fitted with the automatic Case IH Cruise-Cut steering system ensuring the header is always fully utilised. A laser scanner mounted on the cab tracks the edge of the uncut crop and sends steering corrections to automatically guide the combine.
For fans of GPS systems, the 20 Series is also available with AccuGuide, Case IH’s latest generation automatic guidance system.

Mid-range offering
As well as gaining the Short Tube Axial-Flow rotor, the 88 Series combines feature a completely revised and reinforced chassis compared to previous models. The wheelbase has also been increased to optimise weight distribution so that larger and heavier headers can be handled with ease and no additional ballast weights are required.
The new design has also allowed the capacity of the grain tank to be increased to 10,500 litres on the 6088 and 7088. The grain tank on the entry-level 5088 is 8,800 litres.
For the first time in this class of combine, the electric-powered grain tank expansion flaps are now controlled from the cab and these can be closed if required to make the tank watertight.
More power is now available during unloading and the Axial-Flow 5088 achieves unloading rates of 88 lit/second, while the 6088 and 7088 reach 106 lit/second enabling the grain tanks to be completely emptied in less than 100 seconds.
The 88 Series combines feature the same luxury cab used on the 20 Series. The five square metres of glass creates a spacious, comfortable and modern working environment, while the instrumentation is configured in a new layout with the A-post displays providing an overview of status information on the combine such as engine power, header throughput and sieve settings. The 88 Series is also now equipped with a multifunction lever enabling fatigue-free, fingertip control of the machine’s key functions from the right-hand armrest.
Axial-Flow customers can choose from a wide range of headers including the high-capacity 2040 Series with fixed cutterbar, the 2050 Series with variable cutterbar or the 2100 Series maize header.
The 20 Series combines feature a header recognition system that automatically sets up the combine’s systems and controls to match the header fitted. All headers designed for the 20 Series are fitted with the Case IH Terrain Tracker system. This system, which is controlled electromechanically using potentiometers and skids underneath the header, keeps the header parallel to the ground following the ground contours precisely.
