Husqvarna Automower 'Cutting system blocked' on a robot mower
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
The Automower detects that the cutting system is blocked. Husqvarna lists grass or objects wrapped around, the blade disc sitting in a pool of water or grass that is too high (over 10 cm). Switch it off, wear gloves and clean it before restarting.
Safety first
Stop and check this first
- Switch the mower off and wear protective gloves before touching the blade disc: the blades are sharp. Do not clean the mower with a high-pressure washer or solvents. Use only original Husqvarna blades and replace the screws whenever you replace the blades.

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Switch off and put on gloves
- Who:
- you.
- How:
- push STOP, hold the ON/OFF button for 3 seconds and check that the keypad lamp is off. Put on protective gloves before bringing your hands near the wheels or the blade disc.
- Result that matters:
- working with no risk of the disc turning.
- If the lamp is still lit:
- do not touch it until it is switched off.
- If it is disabled:
- go on to cleaning.
- Evidence to keep:
- photo of the display with the message.

Clean the wheels, disc and chassis
- Who:
- you, with the mower off and wearing gloves.
- How:
- clean the wheels with a soft brush. To inspect the disc, turn the mower upside down on a soft surface and clean the disc and chassis with a brush; check that the disc rotates freely and the blades are undamaged and pivot freely.
- Result that matters:
- wheels and disc free of grass and objects.
- If grass or an object was wrapped around:
- remove it and try again.
- If everything is clean and turns freely:
- check the lawn and any water.
- Evidence to keep:
- photo of what was wrapped around and of the clean disc.

Water pools and grass height
- Who:
- you.
- How:
- see whether the mower stopped in standing water or very long grass. Husqvarna says to move it, prevent water collecting and cut the grass to a maximum of 10 cm before using it.
- Result that matters:
- lawn conditions the mower can cut in.
- If there was water or long grass:
- fix the area and restart.
- If neither applies and the message keeps returning:
- speak to your Husqvarna representative.
- Evidence to keep:
- photo of the spot where it stopped.

What it means
In the Husqvarna Automower 405X/415X operator's manual (1650-006, 2023), 'Cutting system blocked' means the cutting system cannot work normally. Husqvarna gives three causes: grass or another object wrapped around (the table places it on the drive wheel and says to clean the wheels and around them), the blade disc lying in a pool of water and grass that is too high, with a maximum of 10 cm before the mower is installed. Other models may differ. The message alone does not prove that the cutting motor is faulty.
