Kress KR120E Mission: Cutting-height / deck movement blocked

What this fault means

Debris or mechanical load prevents cutting-height/deck movement.

Safety: Stop the mower and follow the manufacturer safety instructions before physical inspection.

Step-by-step checks

1. Power down safely.
2. Clean packed grass above/below the cutting plate where accessible.
3. Check the cutting plate can move through its intended range without forcing it.
4. Retry height adjustment on clean level ground.
5. Persistent actuator error requires service rather than repeated forced movement.
