Making its official debut at this year's Agritechnica event in Germany is the new Claas Axion 900 range of tractors. With power outputs of 320hp-410hp, these are the largest conventional tractors that the German firm manufactures before extending into its Xerion systems tractor territory.
The firm says the Axion 900 is a totally new design and has adopted Selective Catalytic Reduction (AdBlue), with a change of engine suppliers from John Deere to Fiat Power Train (FPT) as a means of emission control.
There will be four new models in the range and each will have maximum power outputs of 320hp, 350hp, 380hp and 410hp. All use the FPT Cursor 9, 8.7-litre, six-cylinder, 24-valve engines.
The company says these engines will be controlled by a Claas engine electronic management system and feature a completely electronically managed cooling system using a visctronic, electronically controlled cooling fan.
Matched to the FPT engine is a ZF Eccom 3.0 vario transmission, which has four variable speed working ranges. The rear axle is a French-built GIMA unit, which is from the facility that Massey Ferguson and Renault (latterly Claas) share.
According to Claas, the New Axion 900 series can be fitted with 2.15m tyres, while the suspended front axle can be fitted with tyres up to 1.70m in diameter.
Controlling the transmission is the firm's Cmatic intelligent transmission management system, which is operated via its armrest-mounted Cmotion control unit. Like many variable transmission systems, the driver can select three operating modes, Automotive, Cmotion or Manual.
In Automotive mode, the operator uses either the foot throttle or cruise control to set his forward or reverse speed. The control module then manages engine revs in accordance to what is required, providing optimum fuel efficiency. The Cmotion mode provides a similar system of operation, albeit speed is controlled via the Cmotion lever on the seat armrest. Like many vario systems, there are lots of transmission functions and features that can be set up and stored.
