Movement and manoeuvring made easy

The ROPA Keiler 2 can be equipped with an optional drive axle for increased traction and soil protection even under extremely difficult harvesting conditions. Even with this optional equipment with high-volume 850/50 R 30.5 tyres the road transport width is just 3.00 metres.

The integrated axle freewheel allows speeds up to 40 km/h on the road. A maximum torque up to 14,500 Nm can be achieved at the wheel for a thrust of 2 tons. Coupling and uncoupling while driving is possible at any time. The maximum speed with a coupled drive axle is up to 14 km/h.

The new and practical automatic operation using tractors with ISOBUS is a convenient and elegant solution. The drive axle is automatically actuated in the applicable direction of travel during start-up and controlled synchronously, then switched off again at a standstill. A significant advantage, because it is not necessary to switch, stop or switch the drive axle to reverse separately while moving or starting.


  • Under extreme harvesting conditions the automatic operation consistently eliminates the danger of getting stuck due to activation of the drive axle incorrectly, too late or not at all
  • The automatic operation always moves the drive axle in the correct direction of movement immediately and ensures drive support and movement under the most difficult conditions
  • The ISOBUS automatic operation completely prevents the tractor from being pushed by an activated drive axle or one that is deactivated too late
  • The Auxiliary Control (AUX-N) functions activate the ISOBUS automatic operation for the drive axle and also the most important lifting functions in addition to the terminal with the ISOBUS keys on the tractor or an ISOBUS control
