Claas fields innovation into new tractor range

  • 19-Oct-2011 03:28 EDT

The first Claas Axion 900 preproduction machines went into operation in 2009. Since then, the new tractor has been tested thoroughly in fields throughout Europe and in direct dialogue with users.

Claas' Axion tractor family is set to be joined by four all-new 900 models with maximum power outputs of 320, 350, 380, and 410 hp, extending the current Class tractor range and bridging the gap between the 164- to 260-hp (122- to 194-kW) Axion 800 and 330- to 530-hp (246- to 395-kW) Xerion 3300 to 5000 4x4 high-horsepower tractors.

According to Claas, the Axion 900 embodies an entirely new design concept, encompassing a number of innovative technological advances. For one, the Axion 900 features integrated SCR (selective catalytic reduction) technology. The SCR catalytic converter is housed beneath the engine hood. A separate urea tank is integrated in the fuel tank so that both filler necks are easily accessible next to one another.

The new Axion models also embody the Claas Power Systems (CPS) concept. CPS offers an optimal combination of newly developed components and drivetrain technology. Designers say it is not only about engine performance and compliance with emissions standards but also about the machine as a whole, its efficiency in daily use, and the intelligent use of power. The Axion 900 derives its power from a four-valve 8.7-L six-cylinder common rail FPT Cursor 9 engine. The Axion 900 is the first Claas tractor model that meets Tier 4 Interim.

A further element of the concept is the ZF Eccom 3.0 continuously variable transmission (CMATIC). Four mechanical driving ranges ensure efficient high power transfer and make for a diesel drive concept with high fuel economy. The Axion 900 comes in 40 and 50 km/h (25 and 31 mph) variants. Rear tires with a diameter of up to 2.15 m (7 ft) are available to allow engine power to be transferred to the ground effectively. The machine’s front tires have a diameter of up to 1.7 m (5.6 ft). Front and rear twin tires are optional.

When it comes to agricultural technology, the current trend for fewer, larger machines to cover greater areas is placing increasing demands on both man and machine. As a result, cab comfort and ergonomics become increasingly important. The Axion 900 features a brand new four-pillar cab, developed in close co-operation with farmers across Europe.

User reviews and scientific analysis of driver requirements in terms of cab design and comfort have been incorporated into a new ergonomic concept. This provides, among other things, for optimal visibility forward but also over rear-mounted implements.

Enhanced seat positioning and the convex rear window in the new Axion 900 offer a view of even the widest implements, with no uprights to impair the driver's field of vision. The front axle suspension and the radically revised cabin suspension system provide a comfortable working environment both during field operations and road travel.

The new CMOTION control, which debuted on the Xerion 5000/4500, has been specially developed for ease of use. The new three-finger concept allows for the intuitive control of up to 20 functions without having to adjust the grip. The full-color, easy-to-operate CEBIS terminal is integrated into the new armrest.

Claas expects drivers to find the menu structure very easy to grasp and use. Direct access to all key functions is guaranteed. Up to 20 work lights including Xenon lights provide for 360° lighting, giving the driver an excellent and safe view even in the dark.

For enhanced traction and efficiency, the Axion 900 tractors feature a long wheelbase of 3.15 m (10.3 ft) and a balanced weight distribution. Claas says its compact overall dimensions ensure that maneuverability is not inhibited.
