  Red Zone

  Red Zone— peak power level and is not recommended for extended periods because no power reserve is available.

If indicator moves into the red zone, engine power is maximized and the machine could potentially stall. Reduce load on the machine until indicator moves back into green or yellow zones.

Operating in the following conditions increases power consumption:

• Hilly terrain
• Heavy or wet crop
• Wet ground conditions
• Excessive ground speed
