Claas has unveiled the Arion 4 Cmatic, a new four-model tractor series in the 120-160hp class, at EIMA International 2026 in Bologna, Italy. The range-topping Arion 4.150 Cmatic was immediately named Tractor of the Year 2027 in the Utility category, one of six category winners chosen by a 26-strong jury of European journalists at the show (see our round-up of all six Tractor of the Year 2027 winners).
The Arion 4.120 Cmatic, Arion 4.130 Cmatic, Arion 4.140 Cmatic and Arion 4.150 Cmatic sit alongside the existing Arion 400 range and overlap with the larger Arion 5 Cmatic, bringing a continuously variable transmission (CVT), a premium cab and digital connectivity to a power class where Claas says such features have not previously been available. Each model is offered in Comfort and Business specification.
All four models are powered by a 4.5-litre Cummins four-cylinder engine, delivering up to 118kW (160hp) and 646Nm of peak torque, with the specific rating varying by model. A 228-litre fuel tank is designed to allow long working days without refuelling, and the engines are approved for use with hydrotreated vegetable oil (HVO), which Claas says can cut CO2 output by up to 90%.

| Model | Max power (with Dynamic Power) | Rated power |
| Arion 4.120 Cmatic | 96kW/130hp | 88kW/120hp |
| Arion 4.130 Cmatic | 103kW/140hp | 96kW/130hp |
| Arion 4.140 Cmatic | 110kW/150hp | 103kW/140hp |
| Arion 4.150 Cmatic | 118kW/160hp | 110kW/150hp |
Intelligent power and drivetrain management
The series introduces Claas’s power and drivetrain management systems to this tractor class for the first time. Auto Droop automatically adjusts engine droop to suit operating conditions, while Dynamic Power adapts engine power across the transmission, power take-off shafts, hydraulics and spool valves according to demand.
A further system, Auto Load Anticipation, uses a self-learning algorithm to proactively adjust engine speed and gear shifting ahead of load spikes, such as when an implement is lowered into the ground. Claas says this keeps handling stable during sudden load changes and prevents drops in engine speed; the technology won a silver Agritechnica innovation award.
The Cmatic transmission itself is built by Claas Industrietechnik and allows drivers to switch between pedal mode, joystick mode and power take-off mode without changes in engine or vehicle speed. An optional 50km/h top speed is available, reached at 1,615rpm, with 40km/h achieved at a more efficient 1,300rpm. An automatic trailer overrun brake is fitted as standard on the 50km/h variant and offered as an option on the 40km/h version.
A wheel loader mode is standard across the range, using sensor-controlled electronics to prevent drive-wheel spin during pushing operations, reducing tyre wear and fuel use.
Automated front loader operation
The Arion 4 Cmatic is the first tractor in its class to offer Smart Loading, a front-loader automation system that coordinates lifting and lowering heights, stores end positions for lift arms and tilt angles, and includes automatic bucket return. The system also links a weighing function to job management and the Claas connect platform, allowing loaded materials such as grain, fertiliser or solid manure to be weighed and logged by job.
Panoramic cab and comfort
The cab, built on the Panoramic concept first introduced on the Arion 400, has an internal volume of 2.8m3 and a noise level of 69dB(a), which Claas says make it among the largest and quietest in its class. The Panoramic windscreen, which extends into the roof, is standard on Business models and optional on Comfort variants.
Premium seats are available with ventilation, heating and a massage function, and the seat can swivel up to 30 degrees to the right and 10 degrees to the left. Three integrated cameras monitor the front of the tractor, implements and the front loader, with images viewable and zoomable on the Cebis connect terminal; two further camera connections are available for attachments.
A suspended front axle and new mechanical cab suspension are fitted, along with optional dynamic steering, which Claas says roughly halves the number of steering wheel turns needed between lock positions. A new lighting package offers up to 20 LEDs and a maximum of 48,000 lumens, and the windscreen wiper covers a 280-degree sweep.
Connected machine and farm management
Control is centred on the Cebis connect terminal in the armrest, alongside a further 12-inch touch display; both can run the GPS Pilot steering system and manage implements, front loaders and ISOBUS applications. A new Auto RefLine function automatically detects and switches between reference tracks without driver input.
Claas connect extends to the new range, covering machine position, performance data, maintenance planning and fleet management, with a remote display view allowing the tractor terminal to be viewed off-board for remote support. A new automatic documentation function generates entry suggestions for tractor activities, such as working time, fuel consumption and field maps, which Claas says will let farmers track the profitability of individual fields.
Warranty options
Two service packages are available for the range. Maxi Care Focus is a component warranty covering the engine, gearbox and axles for five years or 5,000 operating hours. Maxi Care Protect extends statutory warranty cover, including parts, consumables and labour, for up to eight years or 8,000 operating hours.
