The New Generation of CLAAS Ag Tractors
Le Mans / Paris, 25.02.2013. Two years ago at the SIMA 2011 trade fair, CLAAS presented a completely new development and design philosophy in tractor manufacturing in the form of the AXION 900. At this year’s SIMA trade fair, CLAAS will present another new model series, the AXION 800. This is based on the same successful principles and has been designed and developed using the same technologies, and as a result the new AXION 800 no longer has much in common with its predecessor of the same name. The first series produced machines will arrive on the market from 2014.
Like the AXION 900, the new AXION 800 has a long wheelbase with a weight distribution of 50% at the front and 50% at the rear and a compact design. To ensure that the tractor remains highly manoeuvrable, its front chassis also shares the “wasp waist” shape of the AXION 900. The radiator package sits on the widest point of the front axle carrier, while the engine is mounted on an extremely narrow oil pan integrated within the frame. The advantage of this slender design is that it allows high steering angles and thus a small turning radius. The robust construction enables the use of front linkages with lifting forces of 3.5 or 5.6 tons without additional reinforcing struts.
Significantly improved operator comfort
Like the 900 series, the new AXION 800 series is equipped with a 4-pillar cab, the CLAAS comfort concept with 4-point cab mounting, vibration damping for the lifting gear and front axle suspension, thus providing significantly improved operator comfort. The similarity of the two tractor model series in terms of their design is clearly evident. The cab is not just located further towards the front, but is also larger and wider. Thanks to a single-piece windscreen without cross-struts and a curved rear window, the operator has a clear view of the attached implements both to the front and rear.
First CLAAS machine compliant with Tier 4 Final standard
The new AXION 800 is the first CLAAS machine equipped with a Stage IV (Tier 4f) engine which meets all future exhaust treatment requirements. This is achieved with a two-stage system consisting of a diesel oxidation catalytic converter (DOC/Oxicat), combined with an SCR catalytic converter. In contrast to a diesel particulate filter, the diesel oxidation catalytic converter is maintenance-free.
With four models ranging in output from 200 to 270 hp, the new AXION 800 completes the CLAAS tractor range, fitting in between the lower powered ARION 500/600, which range from 145 to 184 hp, and the AXION 900 with 280 to 400 hp (as per ECE R 120).
The new six-cylinder FPT engines have a 6.7 l displacement and provide up to 8% more torque than the predecessor model with a constant power range of up to 500 rpm. This means more torque and more power at a reduced rpm and thus less fuel consumption. Another new feature of the AXION 800 is that the full engine power can be used at all times during any application and without limitation.
The new VISCTRONIC fan is electronically controlled and only ever provides the cooling output that is actually required by each radiator element in order to further save fuel.
New decoupling function for front power take-off transmission
Initially, the HEXASHIFT transmission will be available for the new AXION 800, with the continuously variable CMATIC transmission following some time later. The development team from CLAAS POWER SYSTEMS has also developed a new coupling system for the front power take-off transmission on the new AXION 800: if the front power take-off is not required on a seasonal basis, the entire transmission can be decoupled from the engine. The background to this purely mechanical development is that the front power take-off transmission of a tractor is normally driven permanently by the engine but only used seasonally. This means that the gears which rotate continuously in the transmission fluid require drive energy, even if the transmission is not under load. By decoupling the front power take-off transmission from the engine when working without the power take-off, a further 0.4 l of diesel can be saved per hour.
Operation – A choice of CIS or CEBIS
In terms of operation, the new AXION 800 uses the tried-and-tested concept of the ARION 500/600 with CIS or CEBIS versions available. CIS is the basic version with mechanical control units and the CLAAS INFORMATION SYSTEM (CIS) making this ideal for customers who require a tractor with few electronic controls. CEBIS version tractors (CLAAS Electronic on-Board Information System) are equipped with electronic control units and the CEBIS terminal integrated into the armrest. The CEBIS version includes intelligent headland and implement management functions as well as comprehensive connection options for ISOBUS devices. Many tractor and implement functions can now be operated via function keys in the armrest or using the CMOTION multifunction control lever.
