How to Change Blades on a Husqvarna Automower® (Step-by-Step)

Wondering how to keep your Husqvarna Automower® cutting cleanly and efficiently? One of the easiest and most effective ways is to replace its blades regularly. Dull blades can lead to torn grass tips, brown patches, and unnecessary strain on your mower.

In this quick guide, we’ll show you how to change the blades on your Automower® safely and correctly. You’ll learn when to replace them, what tools you need, and how to do it without damaging your machine. Keep reading to extend the life of your mower and improve your lawn's health.

When Should You Change the Blades?

Husqvarna recommends changing the blades every 1–3 months, depending on mowing frequency, lawn size, and debris (like sticks or sand). Signs it’s time to swap them out:

• Grass looks torn or frayed at the tips

• Mower is noisier than usual

• You notice reduced cutting performance

• The mower is leaving uneven patches

If you’ve recently cleared sticks, gum nuts, or bark from your lawn, it may be worth inspecting your blades for chips or dull edges.

What You’ll Need

Before you begin, gather:

• A set of replacement blades (official Husqvarna blades are recommended)

• A Torx screwdriver (usually T20)

• Protective gloves

• A clean, flat surface to work on

If you're unsure which blades suit your model, contact APS Pro Services for guidance or check your model number on the Husqvarna website.

Step-by-Step: How to Change the Blades

1. Turn Off the Mower
   Switch the main power off underneath the unit. Remove the mower from the charging station and ensure it’s completely powered down.

2. Flip the Mower Gently
   Place it upside down on a clean towel or mat to protect the cover. The cutting disc will be fully visible.

3. Unscrew the Old Blades
   Using the Torx screwdriver, remove each screw holding the blade in place. Be careful — the old blades may still be sharp.

4. Remove and Replace
   Align the new blade over the hole and insert the screw. Don’t overtighten — blades should pivot slightly for safety and cutting efficiency.

5. Repeat for Each Blade
   Automowers usually have 3 rotating blades. Change them all at the same time for balanced performance.

6. Dispose Safely
   Old blades should be wrapped and disposed of carefully, especially if children or pets are around.

7. Power Back On & Test
   Once the mower is upright and back in its dock, power it on and run a short test to ensure it’s cutting smoothly.
