Automower blades — how often to replace and what dull blades do
Automower pivot blades are small, cheap, and do their job well — for a while. Husqvarna's
guidance lands around every 1–3 months of cutting depending on lawn size, grass type, and
whether the blades meet anything harder than grass.
Signs your blades are done
- Grass tips look torn and whitish/brown a day or two after mowing instead of cleanly cut.
- The lawn develops a dull, frayed look though the mower runs constantly.
- The cutting motor works harder (on models that report it, cutting time per area rises).
The job
- Power the mower off. Gloves on.
- Turn it over; each blade is held by a single screw on the pivot disc.
- Fit new blades with new screws — the screws are part of the retention design; never
reuse the old ones.
- Check the blades pivot freely after fitting.
The API exposes a blade-usage counter; a tracked history shows exactly how many cutting
hours each set actually lasted on your lawn — more useful than any generic interval.
MowerWatch spots this automatically. It watches your Automower®'s own API data,
reconstructs every stop with its cause, and tells you which part to check — before the
dealer visit.
