Change the wheels on your Husqvarna Automower robotic lawnmower
The running wheels wear out as the robotic lawnmower mows your lawn. Eventually, the robotic lawnmower loses its grip and can get stuck on slopes or hills because it can't get up them.
This usually happens when it is wet outside and the lawn becomes slippery. That's why it's a good to look over the running wheels and possibly replace them with new ones if necessary.

How often should I change the wheels?
How often you should change the running wheels will vary. If you have problems with the robotic lawnmower getting stuck and the track on the running wheels wearing down, it's a clear sign that a pair of new running wheels is needed, so that the robot can regain the grip it needs when mowing your lawn.
Changing the running wheels on your Automower doesn't require any special tools.

See below for step by step instructions.

Step 1: Disconnect the charging cable. Remove the rubber plug and disconnect the connector from the chassis.	Step 2: Remove the chassis from the robot. You do this by holding the back end of the chassis and pulling it firmly upwards. The chassis will be released from the two rear mounts, then you can fold the chassis forward to release it from the two front mounts.
Step 3: Put the robot on its side. Next, use a small flathead screwdriver or other object to remove the hub cap from the driveshaft.	Step 4: Use a size 24 ring spanner or a suitable adjustable spanner to unscrew the nut from the shaft. This screw usually has a left-hand thread.
Step 5: Remove the washer and old running wheel from the axle. Then fit the new running wheel and washer and tighten the nut. Then push the hub cap gently back into place.	Step 6: Reassemble the parts in reverse order, and you're done! Please note! Don't forget to connect the charging cable and press the rubber plug back properly.

Tip! To prevent the nut from unscrewing during operation, you can use a liquid threadlocker.
