Claas Launches Arion 4 Tractor Range
The new 120-150hp Arion 4 models were unveiled at the EIMA show in Italy as Claas keeps its powershift-only Arion 400s in production.
Updated on Nov. 10, 2026 in Trucks
Claas launched a new range of 120-150hp Arion 4 tractors at the EIMA show in Italy on November 10, 2026. The Arion 4 models are offered exclusively with a stepless CVT gearbox and are priced 20% higher than the simpler-spec models that run alongside them.
Why it matters
The launch adds a higher-spec tier to Claas's mid-range tractor lineup while the company continues producing the older powershift-only Arion 400s. The two ranges will be sold side by side, giving buyers a choice between a simpler transmission and a stepless one.
The Arion 4 models deliver 120-150hp, 646Nm of maximum torque and a 5,750kg maximum rear linkage lift, with a 600-hour service interval and a 6,166kg working weight. The new five-post cab offers 24% more glass than before, and the Cebis Connect touchscreen shares features with larger Claas models.
The players
Claas
Claas is a German agricultural machinery manufacturer known for its combines, tractors and harvesting equipment.
Cummins
Cummins is a US-based engine manufacturer that supplies power systems for trucks, industrial equipment and agricultural machinery.
The details
Claas switched from FPT's four-cylinder power plant to a 4.5-litre Cummins engine and uses its in-house Cmatic CVT gearbox. The models employ auto load anticipation, a self-learning algorithm that adjusts engine revs and transmission settings before load spikes, along with an auto-droop function that controls how far revs can drop before ratios change.
Timeline
November 10, 2026: Claas launches the Arion 4 range at EIMA in Italy.
Next couple of years: Arion 400 production continues at Le Mans alongside the Arion 4 models.
Roadmap
The Arion 4 extends Claas's in-house Cmatic stepless transmission into a mid-range tier while the powershift-only Arion 400 continues in production. The dual-range approach reflects a broader industry pattern of offering both simpler and more advanced transmission options at the same power levels.
Buyers comparing Arion 4 models will pay about 20% more than for the simpler Arion models sold alongside them, with base list prices between £153,000 and £162,500. The stepless CVT gearbox is the defining choice between the two ranges.
The takeaway
Farmers weighing a mid-range tractor now face a clearer choice: pay a premium for the stepless Arion 4 or keep the simpler, lower-cost Arion 400. Compare transmission type against your daily workload before deciding.
