Quick answers
What you might notice
- Cutting system blocked message
- Unusual blade noise
Do this
- STOP the mower, switch it off, and place it on its side safely. Remove grass/objects wrapped around the blade disc.
- If stuck on a root/trampoline leg, free it and restart. Create a stay-out zone or island if it repeats in the same spot.
- Replace worn blades on the recommended interval. If the fault returns with a clear disc, request dealer service.
