Making its UK debut at the LAMMA show will be the new CLAAS AXION 900 range of tractors which have power outputs from 320hp up to 410hp.
A total of four AXION 900 models are available, the AXION 920, 930, 940 and 950, which are the first CLAAS tractors to benefit from the recently formed CLAAS Power Systems (CPS), which brings together experts from the different divisions within CLAAS to share information and ideas in order to develop products that best meet customer expectations in terms of performance, reliability and running cost, but also regulatory and environmental requirements.
In order to meet the forthcoming Tier 4i emission regulations for engines of between 176 and 760hp, by not being committed to a specific engine manufacturer, in deciding whether to use EGR (Exhaust Gas Recirculation) or SCR (Selective Catalytic Reduction) engine technology, CLAAS is free to consider which technology is best suited to current and future machines.
Rather than just focussing on the engine and emissions, for all products that fall within these emission requirements CPS take into account all practical aspects of the machine, such as application, transmission, hydraulics, power transmission, etc and from there seek to achieve an optimum match between all components.
Design
In common with all CLAAS tractors, the AXION 900 has a long wheelbase (3.15 metres) for optimum weight distribution and traction, with a compact overall length of 5.56 metres.
The AXION 900 is built around a fully integral frame that incorporates a self-supporting crankcase and embedded sump. This robust design provides the possibility to fit a 6.8t front linkage without the need for any additional bracing, so maintaining maximum manoeuvrability.
The AXION 900 features a brand new four pillar cab design with either the four-point mechanical cab suspension system, or the new highly advanced Z-ACTIV cab suspension which utilises a combination of mechanical, pneumatic and intelligent damping systems.
Built into the right-hand armrest are all the main controls needed to operate the tractor. The main functions are controlled using the CMOTION control which fits comfortably in the right hand. Using just three fingers, all the main controls, such as direction of travel, driving range, Cruise Control, hydraulics, rear linkage, CSM headland management and GPS steering can be controlled, plus a couple of additional function switches allow additional tasks to be allocated.
In front of this is the CEBIS terminal with 21cm screen and an ELECTROPILOT joystick for the hydraulic controls. CEBIS is quickly and easily accessed and used via a push/turn dial and an ESC key. In addition there is direct access to the spool valves, speed ranges, Cruise Control and function keys.
The Cab has been mounted forward of the rear axle, which provides benefits in terms of comfort, but also enhanced visibility over wide implements. The B pillars are mounted slightly forwards thus further improving all round visibility. The cab also features a one piece windscreen
Engines
A total of four AXION 900 models will be available, all of which are powered by FPT Curser 9, 8.7 litre 6-cylinder 24-valve engines with SCR technology that have maximum power outputs of 320hp, 350hp, 380hp and 410hp.
The engine is managed by an advanced CLAAS engine electronic management system, which is designed to provide optimum fuel economy with maximum performance and torque.
The engine features an all-electronically managed cooling system. A visctronic fan provides "as required" cooling, so reducing power requirement, and helping reduce noise and fuel consumption.
To ensure that forward visibility is not compromised, all the SCR components are located in protected positions. The catalytic converter is integrated under the bonnet whilst the 60 litre Ad Blue tank® has been incorporated into the 700 litre fuel tank. This makes filling extremely convenient and easy, but also serves to insulate the tank, which is also heated by the engine coolant.
Transmission
In order to maximise outputs and so reduce fuel consumption per hour, the CPS team have selected a split-power, ZF ECCOM 3.0 transmission. This has four automatically engaged mechanical ranges to ensure the maximum amount of power is transferred to the AXION 900’s rear axle.
The transmission is controlled using the CLAAS CMATIC intelligent transmission management system which is designed to ensure a high tranferrence of power to both the rear axle and the PTO, with minimal fuel consumption. Speed range as standard is from 0.05kph up to 50kph, which makes the transmission ideal for a wide range of field and transport operations.
The main transmission control functions are operated using the new CMOTION control unit. Using a button on the main control panel, the driver also has the option of selecting three operating modes, Automotive; CMOTION or Manual, which can be selected whilst the tractor is moving.
The driver also has the option of three speed range driving modes, which can be set-up and stored using CEBIS, then activated on the move and can be used in both forward and reverse. In addition, a Cruise Control facility allows the operator to select a preset speed in each of the three ranges, which will be useful where a precise speed has to be maintained or at the headland, plus there are three
speed reducing modes.
PTO , hydraulics and linkage
Three different PTO shaft speeds packages can be specified, 1000, 1000+540 Eco and 1000+1000 Eco, selected via a control panel on the ’B’ pillar. If required the PTO can be automatically controlled, according to linkage height.
The factory fitted front linkage and PTO is fully integrated into the tractor frame and runs at 1000rpm at an engine speed of 2000rpm and has a maximum power output of 204hp, making this ideal for implements such as a front mower.
The AXION 900 has a 150l/min or 220l/min load sensing hydraulic system and up to six spool valves can be fitted at the rear and two at the front. The rear linkage on the AXION 900 has a maximum lift capacity of 11 tonnes whilst a front linkage with capacity of 3.3 tonnes or 6.8 tonnes is available, which is fully integrated into the frame and so requires no further reinforcement.
Standard Specification
As standard, the AXION 900 is equipped to a high specification to ensure optimum driver comfort and convenience over the long hours that a tractor of this size is likely to work.
In the cab there is a wide range of connection options, including ISOBUS, to ensure that all types of terminal can be easily utilised. The cab also features full air-conditioning and optional automatic climate control, plus a refrigerator box is located under the passenger seat.
