Up to 155 hp with CPM
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. The series now includes seven models ranging from 90 to 155 hp maximum output with CPM in accordance with ECE R120. This means that with CPM, the new flagship model, the ARION 470, delivers a maximum output of up to 155 hp and 631 Nm maximum torque.
All models from the smallest ARION 410 right up to the most powerful ARION 470 are equipped with 4.5 l 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 not only run cleanly, but are still highly efficient, with low diesel and low AdBlue consumption. A fuel tank with a capacity of 140 to 190 l is enough for long working days, while the 17 to 22 l AdBlue tank needs refilling only with every second refuelling.
All engines are extremely maintenance-friendly too; with a 600-hour oil change interval, radiator panels that pivot forwards for easy cleaning and an air filter mounted in front for easy access that needs only occasional cleaning since the cyclonic pre-cleaner removes around 90% of the dirt from the intake air.
Efficient powershift transmission
From the ARION 430 upwards, purchasers can choose between two proven, highly efficient powershift transmissions. The QUADRISHIFT (standard in the ARION 410 and ARION 420) offers 16 forward and 16 reverse gears, split into four ranges each with four powershift speeds. The optional HEXASHIFT transmission has six powershift speeds and 24 forward and reverse gears. A creep gear option down to 150 m/h is available for both transmission variants. The HEXASHIFT achieves the top speed of 40 km/h at 1840 rpm.
With the QUADRACTIV and HEXACTIV auto-shift function, both transmissions can be shifted automatically by pre-selecting either powershift speeds only (field mode) or both powershift speeds and ranges (road mode), which automatically selects the right powershift speed when range shifting. Within the transmission settings, there are three auto-shift modes (fully automatic, PTO mode and manual mode) which the operator can program to suit the job in hand. The auto-shift function is available for ARION 400 tractors with the CLAAS INFORMATIONS SYSTEM (CIS).
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. In the CIS, the operator can easily program the right gears for turning manoeuvres during front loader work or at the headland, as well as the start-up gear for manual or automatic shifting to suit individual requirements. The responsiveness of the reverser can also be adjusted in nine stages. With the HEXACTIV auto-shift function, it is also possible to program the cruise control speed.
SMART STOP it another convenient function designed to lighten the workload. It automatically disengages the transmission when the brake is pressed to bring the tractor to a standstill, and automatically re-engages it in the programmed start-up gear when the brake pedal is released.
