The Arion 400 range of tractors from Claas has been given a makeover to mark the introduction of new Stage V emissions compliant models in the final Quarter of 2021.
The offering will include 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. What’s more, the range will also benefit from more hydraulic power, more lift capacity and a higher gross vehicle weights.
Claas has equipped its Arion 400 tractors with a range of new performance-enhancing features to mark the introduction of the Stage V emissions standard. Added to the range is the new, more powerful Arion 470 flagship model that has a maximum power output of 155hp. As before, the specifications available for the now seven-model range starting at 90hp will include low cab or the Panoramic cab options, plus either the CIS or CIS+ control systems.
All models are equipped with 4.5-litre, four-cylinder Fiat Powertrain Technologies engines that incorporate the latest four-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 (selected catalytic reduction on filter) technology and a diesel oxidation catalytic (DOC). This means that the engines not only run cleanly, but remain highly efficient, with low diesel and AdBlue consumption.
From the Arion 430 upwards, purchasers will have the choice between the 16×16 Quadrishift or 24×24 Hexashift powershift transmissions. The Revershift clutchless reverser enables easy direction changing using the shuttle lever on the steering wheel console, and optionally also via the multifunction control lever on the right-hand armrest – particularly handy for front loader work.
Smart Stop is another convenient function designed to lighten the workload as it enables the transmission to be automatically disengaged when the brake is pressed, and is re-engaged when the brake pedal is released.
The Arion 400 combines the benefits of a long wheelbase of 2.49m (Arion 410 and Arion 420) or 2.53m (Arion 430 to Arion 470) with a short overall length. Despite its compact dimensions, the redesigned tractor guarantees safe transport of attached implements and exceptional stability for front loader work. This is partly down to its static 50:50 weight distribution without ballast, but the gross vehicle weight has also now been increased to 9.0t, permitting payloads of up to 3.8t.
As on the previous 400 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.
