Quick answers
What is wrong?
Cutting system blocked — grass or an object is stopping the blade disc.
What you might notice
- Cutting system blocked message
- Unusual blade noise
Can I fix this myself?
Usually yes for cleaning/checking. Difficulty: easy · about 10-20 min. If unsafe or unresolved, use mail-in repair / authorised service.
What you need
- Gloves
- Blade screwdriver/torx as per manual
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.
