Cutting system blocked: Automower® error message
The Cutting system blocked message indicates that something is blocking the blade disc. Here are the common causes and solutions:
Lawn mower stuck on an object
- Cause: The lawn mower is stuck on an object like a tree root or trampoline leg.
- Solution: Remove the lawn mower from the object and restart it.
- If it frequently gets stuck in the same spot, consider isolating the problematic area with an island or a stay-out zone.

Grass or objects wrapped around the blade disc, wheels or under the cutting deck
- Cause: Grass or other objects are wrapped around the blade disc and need to be removed.
- Solution: Check for debris under the cutting deck, around the wheels and in between the body and chassis.

Grass too high
- Cause: The grass is too high for the lawn mower to handle.
- Solution: Adjust the cutting height on the lawn mower and ensure the grass does not exceed the maximum height recommended for your Automower® model. See table below.
