Continuously variable drives for ease and comfort.

• Absolutely smooth acceleration from 0 to 50 km/h (or 40 km/h), even under maximum load
• Low fuel consumption on the road thanks to a maximum driving speed at just 1,500 rpm
• Active standstill control (powered zero) for easy stopping and starting on slopes without using the service brake
• Smooth and automatic drive ratio changes
• Consistent engagement of the optimum drive ratio
• Two drive ratios, which change the power flow and functional processes in the transmission
• High, consistent efficiency for low fuel consumption and maximum versatility in all operations

In the first drive ratio, the tractor can be kept in powered zero mode, started up or reversed, without any mechanical shifting operations in the transmission. The stepped planetary transmission splits the power from the engine (from the left) into a mechanical and a variable, hydrostatic component. As the tractor accelerates, the rotational speeds of the two clutch shafts gradually converge until they are synchronised, at which point the drive ratio is changed automatically without the driver even noticing.

In the second drive ratio, the power flow and the functions in the transmission change. The hydrostats switch their functions. The stepped planetary transmission is intelligently connected to the hydrostats via the clutches. This ensures that the power from the engine is not only split by the stepped planetary transmission, but also converges again behind the hydrostats.

Powerful acceleration, smooth deceleration and a fast response to load changes: CMATIC powertrain management delivers consistently high performance in all conditions and for every task. Stay relaxed and focused throughout the working day so you can concentrate on more important things – and let CMATIC take care of the rest.

The described change in function between drive ratios 1 and 2 ensures consistently high efficiency at all speeds, making the ARION 600 / 500 CMATIC tractors particularly powerful.
