CLAAS has updated its ‘all-rounder’ tractor ranges – the versatile Arion 600 and 500 new generation machines get more equipment options, a wider range of engines and many new features.

Changes include the new CIS+ system, a new Cebis terminal, updated Hexashift and CMatic transmission functions and the new easy-rider Proactiv front axle suspension.

Three equipment options will be available for the first time across the ranges basically centred around the control systems, CIS, new CIS+ and the new CEBIS Touch, and these options will extend to the Axion 800 models too.

All can be had with the Hexashift powershift transmission; alternatively, the CIS+ and CEBIS versions can also be supplied with the continuously variable CMatic transmission. The ‘no frills’ CIS version has been kept deliberately simple, with mechanical spool valves and the CIS display, while CIS+ comes with electronic spool valves and the CIS colour ‘A’ pillar display as standard. Both will have the proven multi-function armrest Drivestick to operate the transmission.

The CEBIS version has a redesigned terminal with 12-inch touch screen display and intuitive Direct Access, in addition to the CMotion easy to use multi-function control lever.

On the engine front, the power range has been extended upwards and downwards and now stretches from 125hp in the Arion 510 to 185hp (205hp with boost) in the Arion 660.

All 500 machines have a four-cylinder engine, while the 600 tractors get a six-cylinder power plant across the range, with these having a new engine idling speed reduced from 800 to 650 rpm when the tractor is stationary, delivering fuel savings.

All meet the requirements of the Stage IV (Tier 4f) emissions standard thanks to a combination of diesel particulate filter (DPF) and SCR catalytic converter (selective catalytic reduction). As well as the inclusion of an AdBlue tank, the diesel tank capacity has also been increased.

The six-speed Hexashift gearbox gets more functions. These include a cruise control function where the forward speed selected by the driver is maintained automatically at the optimum engine speed, with the engine operating independently of the current task which makes for optimum fuel use.

An integrated Smart Stop function means that when the brake pedal is pressed, the transmission disengages automatically – there is no need to use the clutch pedal. This reduces the driver’s workload, especially during clutch-intensive tasks such as front loader work and round baling.

The continuously variable CMatic transmission also has upgraded software, which refines engine-transmission co-ordination. The ranges also have an upgrade available for the hydraulic system, which adds a 150 l/min set-up to the standard 110 l/min.

All new Arion 600 and 500 models get the option of the new Proactiv front axle suspension which is designed to provide active roll stabilisation on bends as well as reducing pitching movements during braking and acceleration. It is particularly beneficial when driving with heavy implements attached as it prevents ‘bounce’.

An updated range of cabs means that customers can choose between the familiar five-pillar cab, or a four-pillar cab – as used in the Axion 900 and 800s – with uninterrupted vision to the driver’s left. They also, for the first time, get the safety of electronic ‘parklock’ parking brake on the Revershift shuttle lever.
