The Arion 400 range of tractors have been given a makeover to mark the introduction of the Stage V emissions standard, Claas has announced.
This makeover has meant a new design, a more powerful top-of-the-range model and Claas Power Management (CPM) to boost power in the Arion 440 and above.
The German machinery firm also promises more hydraulic power, more lift capacity and a higher gross vehicle weight in this range update.
Due to be launched in Ireland and the UK this autumn, Claas has equipped its Arion 400 tractors with new “performance-enhancing features” to mark the introduction of the EU’s Stage V emissions standard.
All models are equipped with 4.5L four-cylinder Fiat Powertrain engines which incorporate the latest 4-valve technology and turbochargers with intercooling.
Turbochargers from the Arion 430 upwards are also fitted with a wastegate. The Stage V aftertreatment system cleans the exhaust gases using an effective combination of SCRoF technology (Selected Catalytic Reduction on Filter) and a diesel oxidation catalytic converter (DOC).
This means that the engines run cleanly, but are still highly efficient, “with low diesel and low AdBlue consumption”, Claas adds.
From the Arion 430 upwards, purchasers can choose between the 16×16 Quadrishift or 24×24 Hexashift powershift transmissions.
The Revershift clutchless reverser apparently allows for “easy direction changing” using the shuttle lever on the steering wheel console. There is also an option via the multifunction control lever on the right-hand armrest – particularly handy for front loader work, the manufacturer claims.
Smart Stop is a feature designed to lighten the workload, enabling the transmission to be automatically disengaged when the brake is pressed, and re-engaged when the brake pedal is released.
In terms of dimensions, the Arion 400 combines the benefits of a long wheelbase of 2.49m (Arion 410 and Arion 420) or 2.53m (Arion 430 – Arion 470) with a short overall length.
The machine has a static 50:50 weight distribution without ballast but the gross vehicle weight has now been increased to 9.0t, permitting payloads of up to 3.8t.
As on the previous series both the fully integrated front linkage and factory-fitted front loaders can be conveniently controlled by the multifunction control lever, with the option of also controlling the front loader by Electropilot (CIS or CIS+) or Flexpilot.
Proactiv front axle suspension, mechanical two-point cab suspension and various seating options will also be available to further increase driver comfort, Claas claims.
