Frequently Asked Questions

How often should I clean my Husqvarna Automower's cutting system?
Clean the cutting system monthly during mowing season, or more frequently if you notice grass buildup. Regular cleaning prevents Error 25 and extends blade life.
Can I prevent Husqvarna Automower Error 25 from occurring?
Yes, by keeping your lawn free of debris like sticks and wire, mowing when grass is dry, and performing regular maintenance cleaning of the mower's underside.
What if Error 25 keeps coming back on my Automower?
Recurring Error 25 may indicate worn blades that aren't cutting cleanly, leading to more grass buildup. Replace the blades and ensure your lawn doesn't have excessive thatch buildup.
Is it safe to clean my Automower while it's wet?
No, always ensure the mower is dry before cleaning and never clean it while it's charging. Wait for dry conditions and turn off the main switch before maintenance.
How do I know if my Automower blades need replacement?
Replace blades when they appear dull, chipped, or if Error 25 occurs frequently despite regular cleaning. Fresh blades typically last 2-3 months depending on usage.
