CLAAS Launches ARION 5 CMATIC Tractors with Continuously Variable Transmission

Agricultural machinery manufacturer CLAAS has introduced the ARION 5 CMATIC tractor series, replacing the previous ARION 500 line with three four-cylinder models engineered with continuously variable transmission architecture. The machine series targets multi-purpose agricultural applications across field tillage, grassland maintenance, road transport, and loader tasks.

Powertrain Mechanics and Predictive Load Regulation
The series comprises three models: the ARION 5.140 CMATIC (145 horsepower, 619 Newton-meters of torque), the ARION 5.160 CMATIC (165 horsepower, 697 Newton-meters of torque), and the flagship ARION 5.180 CMATIC (180 horsepower, 730 Newton-meters of torque at 1,500 rpm). Power is supplied by a 4.5-liter four-cylinder engine delivering full rated power on a permanent basis without reliance on transient boost curves. The flagship model registers an unladen operating weight of 7,700 kilograms, establishing a power-to-weight ratio of 42.8 kilograms per horsepower.

Mechanical power transfer relies on the continuously variable, power-split CMATIC gearbox manufactured by CLAAS Industrietechnik. The transmission management incorporates an automated load anticipation algorithm. This control system registers implement drop commands in real time, elevating engine revolutions and reconfiguring transmission ratios before soil engagement causes torque spikes. For road transit, the transmission attains a maximum forward velocity of 50 kilometers per hour at an engine speed of 1,490 rpm, coupled with an automatic trailer overrun brake system to regulate deceleration stability. A dedicated loader mode adjusts throttle and hydraulic interactions to optimize traction while reducing tire scrubbing during material handling cycles.

Operator Station and Chassis Isolation Systems
Chassis dynamics combine a multi-link PROACTIV front axle suspension with a fully isolated four-point cab suspension system. In-cab implement and transmission operation is consolidated through the CMOTION multifunction lever, which places speed ranges, eight programmable controls, rear linkage positioning, and headland management sequences within single-hand reach.

Primary telematics and machine configuration menus are navigated via the armrest-mounted CEBIS display terminal. Available cab appointments include a semi-active suspension seat equipped with climate moderation and massage cycles, dynamic ratio steering that reduces total steering wheel rotations by approximately half from lock to lock, and an external lighting array containing up to 20 LED work units alongside illuminated access steps.

Precision Agriculture and Fleet Telematics Infrastructure
Machine guidance relies on the CEMIS 1200 terminal combined with GPS PILOT hardware. The terminal features an automated reference-line tracking protocol that calculates implement track direction and heading relative to field boundaries, automatically alternating between parallel runs and headland sweeps. Waypoints, reference tracks, and completed task maps can be transmitted online through CLAAS connect or transferred machine-to-machine between operational units in identical plots.

The optional CEMOS DIALOG operator assistance system evaluates operating telemetry to provide real-time recommendations for wheel ballasting, implement draft points, and internal tire pressures. Implements connect through a 150-liter-per-minute load-sensing hydraulic circuit capable of driving six auxiliary spool valves, backed by an integrated front linkage, quick-change lower links compatible with CAT 3 and CAT 3N hitches, and a K80 ball hitch rated for 4.0 metric tons of vertical drawbar load. The product line made its public debut at the Innov-Agri exhibition on September 9 and 10 in Ondes, France.

This section details technical specifications and competitive benchmarking not included in the original product announcement

The four-cylinder premium tractor category in the 140 to 180 horsepower segment includes established benchmarks such as the Fendt 500 Vario series (specifically the 516 Vario) and the John Deere 6R 150. In this operating bracket, manufacturers balance chassis compact dimensions against gross payload limits. The ARION 5.180 CMATIC provides an unladen weight of 7,700 kilograms against a maximum permissible gross vehicle weight of 11,000 kilograms, yielding a 3,300-kilogram payload capacity. By comparison, the Fendt 516 Vario utilizes a 4.04-liter Deutz four-cylinder engine generating a maximum output of 163 horsepower, with an unladen weight of approximately 6,400 kilograms and a maximum gross capacity of 10,500 kilograms. The John Deere 6R 150 relies on a 4.5-liter four-cylinder engine providing 150 horsepower rated output (reaching 165 horsepower maximum without Intelligent Power Management, and up to 177 horsepower with IPM boost) on an unladen chassis weight of approximately 6,500 kilograms.

Hydraulic delivery rates represent another measurable operational benchmark across this class. The standard 150-liter-per-minute load-sensing pump on the ARION 5 CMATIC matches or exceeds standard installations in competing four-cylinder platforms, where factory baselines frequently specify 110 liters per minute on standard configurations (with 152 to 158 liters per minute offered as optional configurations on the Fendt 500 Vario and John Deere 6R platforms). Additionally, while competing units frequently achieve headline horsepower figures through electronic engine power boost parameters activated strictly during transport or high PTO loads, the ARION 5.180 CMATIC generates its 180-horsepower ceiling continuously across all draft and stationary applications.
