One for all: The new ARION 4 CMATIC from CLAAS combines premium comfort with intelligent drive technology and maximum versatility.

At EIMA 2026 (10–12 November), CLAAS will be unveiling a completely newly developed tractor series in the 120 to 160 hp range. The ARION 4.120 CMATIC, ARION 4.130 CMATIC, ARION 4.140 CMATIC and ARION 4.150 CMATIC – available in COMFORT and BUSINESS variants – complement the product range alongside the ARION 400 and overlap with the ARION 5 CMATIC, combining efficient and intelligent drive technologies with uncompromising comfort and digital solutions from CLAAS.

As well as their technical merits, these manoeuvrable all-rounders impress with optional service contracts and extended warranties.
 

The ARION 4 CMATIC series at a glance:

Powerful and economical: Cummins four-cylinder engine with DYNAMIC POWER and AUTO DROOP.

All ARION 4 CMATIC models are powered by a latest-generation Cummins four-cylinder engine with a 4.5 l displacement, delivering up to 160 hp maximum power output and up to 646 Nm maximum torque. As with the larger ARION and AXION tractors, peak power and maximum torque are available across a wide rev range of around 500 rpm and are accessible even at low engine speeds from around 1,100 rpm. 

The cooling packages can be easily folded open for simple and effective cleaning. The engines are approved for operation with hydrotreated vegetable oils (HVO), enabling sustainability and a CO₂ footprint reduced by up to 90 per cent. A 228 l fuel tank volume allows for long working days without the need for refuelling.

CEMOS AUTO POWERTRAIN for intelligent power management and adaptive driveline management.

With the new ARION 4 CMATIC, intelligent power and drivetrain management is now also available in the 120 to 160 hp tractor class. 

• AUTO DROOP automatically and adaptively adjusts engine droop to suit the condition of use.
• The new dynamic power management system, DYNAMIC POWER, in turn, intelligently and fully automatically adapts engine power to a wide variety of operating situations and distributes it via the transmission, power take-off shafts, hydraulics and spool valves precisely to where it is needed at any given moment. The system continuously analyses electrical power requirements, optimises the settings and thus ensures high productivity and low fuel consumption at both full and partial load, resulting in lower operating costs.
• The innovative adaptive drivetrain management system with AUTO LOAD ANTICIPATION is groundbreaking; it continuously and proactively optimises engine speeds and gear shifting based on a self-learning algorithm and various efficiency maps for the engine, continuously variable transmission, hydraulics and auxiliary units. Thanks to this ‘artificial intelligence’ – which won a silver Agritechnica Award – load spikes – such as when lowering an implement into the ground – are detected in advance, and the engine speed is proactively increased, with gear shifting adjusted accordingly, before the load spike occurs. This ensures that handling remains stable even during dynamic changes and prevents drops in engine speed. Further functions of the innovative technology regulate engine speed and gear shifting depending on load, driving speed and hydraulic demand. This ensures that the required power is delivered under all conditions of use whilst minimising fuel consumption. The result is highly dynamic yet fuel-efficient driving performance, without the need for manual input or action from the driver.

In combination with the CMATIC continuously variable transmission, CEMOS AUTO POWERTRAIN delivers greater area output with lower fuel consumption – without any additional effort.

Smart CMATIC power train with wheel loader mode and automatic trailer overrun brake.

The ARION 4 CMATIC tractors are equipped with a newly developed, continuously variable CMATIC gearbox with power split from CLAAS Industrietechnik. Just as with the larger ARION and AXION tractors, drivers can change direction smoothly, as well as switching seamlessly between pedal mode, joystick mode and PTO mode without any changes in engine speed or vehicle speed. In every driving mode, override via the ground drive pedal or the CMOTION is possible at any time without interruption – for truly stepless driving at the highest level.

The intelligent power train enables a setup optimised for performance, comfort and efficiency across all areas of application – with a level of automation unique in this power class. This enables even less experienced drivers to work at the highest levels of performance and efficiency across all areas of operation – from front loader and transport tasks through to heavy tillage and combined towing, power take-off shafts and hydraulic operations.

As one of the few models in this tractor class, the ARION 4 CMATIC offers an optional top speed of 50 km/h, enabling time-saving manoeuvring and swift transport on the road. Depending on the tyres fitted, the maximum speed of 50 km/h is achieved as early as 1,615 rpm, whilst 40 km/h is reached at an efficient 1,300 rpm. The automatic trailer overrun brake, a feature designed to provide even greater safety when driving on the road with pneumatically braked trailers and attached implements, is also available on the ARION 4 CMATIC – as standard on the 50 km/h version and as an option on the 40 km/h variant. 

The wheel loader mode is also part of the standard equipment. Sensor-controlled electronics prevent the drive wheels from spinning during pushing operations, which reduces tyre wear, protects sensitive surfaces and lowers fuel consumption. Another useful feature for front loader work: the direction of travel can be changed not only using the CMOTION drive lever and the REVERSHIFT lever to the left of the steering wheel, but also via the ELECTROPILOT.

Front loader automation similar to that on wheel loaders and telescopic handlers

In addition to wheel loader mode, the new ARION 4 CMATIC offers SMART LOADING driver assistance for front loader operations for the first time.  This unique system precisely coordinates all functions that contribute to optimising loading cycles. This includes programmable lifting heights and lowering heights, as well as storable end positions for the lift arms and tilt angles, as well as automatic bucket return for faster and more precise loading cycles. 

SMART LOADING also enables the documentation of front loader operations. The weighing function is linked to job management and CLAAS connect, allowing goods loaded or handled, such as grain, fertiliser or solid manure to be precisely weighed and documented on a job-by-job basis.

The hydraulic bucket shake function via the ELECTROPILOT is also helpful when unloading sticky loaded materials such as soil, silage or other substrates.

PANORAMIC cab with plenty of space and premium equipment: unobstructed visibility during front loader operations.

For the ARION 4 CMATIC, CLAAS has consistently further developed the PANORAMIC concept first introduced in the ARION 400. The new premium cab combines the spaciousness and driving and operator comfort of large tractors with the unique all-round visibility provided by the PANORAMIC windscreen, which extends into the roof – standard on the BUSINESS variant and optional on COMFORT models. 

Thanks to carefully selected materials and high-quality finishes, the cab exudes a genuine premium feel. Premium driver’s seats – optionally available with seat ventilation, seat heater and a massage function – ensure that even long working days pass without stress or strain. Thanks to the wide swivel angle of up to 30 degrees to the right (and 10 degrees to the left, to make getting in and out even easier), you can keep an eye on implements without straining, whilst keeping your legs fully extended and resting comfortably on new foot rests on the right-hand A pillar. 

Furthermore, the performance of front- or rear-mounted implements, or the working area of the front loader (when stacking or unloading), can be monitored via three integrated cameras. A particular highlight is the ability to zoom in and out of camera images digitally and in high resolution on the new CEBIS connect terminal, and to pan the camera in the required direction with a swipe of the finger. The camera integrated between the front headlights allows the area directly in front of the tractor to be monitored, and makes it easier to attach front implements or front ballast weights. Two further external camera connections are available for attachments – for example, front loaders, potato harvesters or auger wagons. What’s more, when reversing, the image from the rear camera is automatically displayed on the CEBIS connect screen.

At just 69 dB(A), the new cab of the ARION 4 CMATIC is one of the quietest in this power class. Numerous storage compartments also provide non-slip, roll-proof storage space for documents, snacks and drinks, as well as work boots or work gloves.

The ELECTROPILOT joystick to the right of the CMOTION allows up to 30 hydraulic and ISOBUS functions to be saved. During field work, the optional dynamic steering reduces the driver’s workload. The number of steering wheel turns required between one steering limit and the other is roughly halved – a noticeable relief, particularly during tight turning manoeuvres at headlands. 

The newly designed mechanical full suspension, engineered for durability, is optimally tuned to work in tandem with the suspended front axle – which requires just six lubrication points.

A new 360-degree LED lighting concept with up to 20 LED lights delivering a maximum of 48,000 lumens ensures a wide field of vision even during night shifts, thereby enhancing safety and enabling the driver to maintain optimal visual control over the quality of the work.

What’s more, access to the five-post cab has been optimised and has the widest width in this tractor class. A fold-away access ladder on the right, handholds and handrails on the cab make it easier to clean the side windows. The windscreen wiper covers a 280-degree sweeping area, thereby guaranteeing the best possible forward visibility at all times.

Intuitive CEBIS connect with integrated GPS PILOT for maximum flexibility.

Control of the most important functions is clearly organised and centralised in the control armrest, featuring the CMOTION drive lever and integrated, interactive CEBIS connect Alongside the 12-inch main screen, all information and applications can also be displayed on a further 12-inch touch terminal, and all functions can be set and configured on both terminals. Users can switch freely between the two terminals – whichever is best suited to the task at hand. This means that the GPS PILOT steering system can be displayed both on the CEBIS connect main screen in the armrest and on the additional 12-inch terminal.

Furthermore, CEBIS connect is used not only to set and monitor the parameters of the ARION 4 CMATIC, but also to manage work processes involving implements or front loaders, as well as automated steering, ISOBUS applications and work orders.

A further, height-adjustable monitor in the right-hand A pillar clearly displays only the most important machine parameters such as speed, fuel consumption, power take-off shafts and the hydraulic control circuits. 

Comprehensive automated headland management and tramline management.

For precise track guidance with CEBIS connect, the optimum reference lines can be planned directly in the terminal or in advance in CLAAS connect based on the field boundaries, and then used and shared with other CLAAS machines with just a few clicks – for example, when harvesting forage with the leading ARION powering a triple mower combination to the following ARION 4 CMATIC with a rake. 

The new Auto RefLine function automatically detects the appropriate or logical reference track based on the vehicle’s position and direction of travel, and switches automatically between different reference tracks. This means that the driver does not need to intervene manually to switch tracks – for example, when switching to headland reference tracks or when working on wedges with a different reference track – making the job significantly easier.

From machine management and fleet monitoring to Precision Farming: the new ARION 4 CMATIC is digitally connected via CLAAS connect.

From machine configuration, purchase processing, access to product documentation and the lubricant guide, through to maintenance planning and documentation, right up to multi-manufacturer fleet management, application maps and other smart farming applications: With just one CLAAS ID, CLAAS connect enables comprehensive connectivity for the new ARION 4 CMATIC too, featuring online task management and access from the office or via a mobile device whilst on the move. Basic features such as machine position, machine performance data, the lubricant guide and direct access to the CLAAS Parts Shop for ordering suitable wear and spare parts can be supplemented, if required, with the Farm connect, Fleet connect and Field connect licences. These include, for example, clear job management as well as real-time display of machine position and status, along with current machine data, settings and performance data on mobile devices and office PCs.

New: Automatic documentation with profitability analysis.

CLAAS is expanding its digital documentation capabilities with the introduction of automatic documentation for tractors. The new function simplifies and optimises the recording of tractor activities and builds on the documentation solutions already available for CLAAS harvesting machinery.

The function, available via CLAAS connect, generates automatic entry suggestions based on machine data. Customers can activate or deactivate the function individually for each tractor via a dedicated button on the terminal ( ), offering maximum flexibility to suit different operational requirements and customer preferences. The suggestions include key operational information, such as the type of activity, working time, fuel consumption and field maps. Information on applied products, such as seed or fertiliser, is not recorded automatically and can be added to CLAAS connect at a later date. With ‘Automatic Documentation for Tractors’, CLAAS supports more efficient farm management by making it easier to record, review and utilise operational data. Thanks to the data recorded, farmers can keep a constant eye on the profitability of their field work without any additional effort.

Another new feature is the analysis of costs and revenues. In the digital field map, farmers can now see what costs were incurred on a field and what revenue was generated. This allows them to see at a glance how the work carried out in the respective harvest year paid off. It also enables a direct comparison of different fields to identify particularly profitable areas and understand how the use of different resources and operating resources affects the operating result.

Hedging costs proactively: MAXI CARE Focus and MAXI CARE Protect for up to eight years or 8,000 operating hours.

Today, professional farmers and contractors want to secure their machinery costs in advance. With MAXI CARE Focus for the ARION 4 CMATIC, CLAAS offers an optional solution tailored entirely to customer needs. The new component warranty covering the engine, gearbox and axles is valid for five years or 5,000 operating hours. 

MAXI CARE Protect goes one step further: this extended warranty covers all claims included in the statutory warranty for a period of up to eight years or 8,000 operating hours – including the cost of genuine CLAAS spare parts, consumables and repair work.
