Controls engine rpm.

To decrease engine speed press switch (A) "Turtle".

Shortcut switch (B) can be used to quickly adjust low or high idle:

• If the shortcut switch is pressed one time, low idle will be implemented by the engine control unit.
• If the shortcut switch is pressed two times, high idle will be implemented by the engine control unit.

To increase engine speed press switch (C) "Rabbit".

NOTE: The increase and decrease rates are independently configurable, see On-Board Diagnostic addresses:

Automatic Engine Speed Adjustment

For several vehicle functions, the electronic system automatically requests appropriate engine speed without any additional operator intervention.

Furthermore the engine speed is limited whenever the road safety switch is in road position and 3rd gear is engaged. In this condition, the automatic engine speed control will adjust the engine speed to 1650 rpm in order to limit the ground speed of the forage harvester and to be compliant to road traffic regulations.

Current engine speed will also be limited whenever the speed sensor on the front axle is indicating that the speed is beyond 1000 rpm. This will also result in a limitation of the ground speed and thus will ensure safe vehicle operation.
