The continuously variable EQ200/220 transmission for the ARION 500/600 is a proprietary development by CLAAS. This intelligent combination of stepped planetary gearbox, clutch unit and two hydrostatic units guarantees optimum power flow. The transmission is very simple in structure, with two automatically shifted drive ratios.

The technology.
Drive ratio 1:
In the first drive ratio the tractor can start up, reverse or remain stationary in powered zero mode. (There are no mechanical shifting operations in the transmission.) The stepped planetary transmission splits the power coming from the engine (from the left) into a mechanical component and a variable, hydrostatic component. When the tractor accelerates, the rotational speeds of the two clutch shafts become closer and closer until they are the same. The drive ratio changes automatically at this point without the driver noticing.

Drive ratio 2:
In the second drive ratio the power flow and functions in the transmission change. The hydrostats switch function. The stepped planetary transmission is intelligently connected with the hydrostats by means of the clutches. As a result, the stepped planetary transmission splits the power coming from the engine (from the left), then combines it again downstream of the hydrostats

Superior transmission control.
Powerful acceleration, smooth deceleration and a fast response to changes in load: CMATIC powertrain management shows its capabilities in all conditions and for every task. Stay relaxed and focused throughout the working day so you can concentrate on more important things – CMATIC does the rest for you.

The change in function between drive ratio 1 and drive ratio 2 guarantees consistently high efficiency at all speeds. ARION 600 / 500 CMATIC tractors are especially powerful as a result.

Efficient and user-friendly.
With engine speeds of 1,500 rpm at a top speed of 50 km/h and 1,400 rpm at 40 km/h, ARION 600 / 500 tractors also demonstrate their full capabilities in transport operations. If the accelerator is not depressed, the transmission is in powered zero mode and maintains its position reliably without creeping or rolling. This means that the tractor can start up safely and easily at steep field entrances or road junctions, even with a full load.

The benefits for you:

  • Completely smooth acceleration from 0 to 50 km/h (or 40 km/h), even under maximum load
  • Low fuel consumption on the road as maximum forward speed is reached at just 1,500 rpm
  • Powered zero mode makes it easy to stop on slopes and start off again without using the service brake
  • Drive ratio changes smoothly and automatically
  • You are always in the right drive ratio
  • Two drive ratios, which change the power flow and processes within the transmission – consistently high efficiency levels for low fuel consumption and maximum versatility in all applications
