How to replace the mower blades?

Make sure to put Willow in Emergency Stop first by holding your hand in front of the screen.

You should use a Screwdriver for slot-head 6,5mm.

The screws are fixed with loctite, make sure to use the correct screwdriver and when you do so, apply a little bit of force to  loosen the screws.

You can remove the mowing disc, but make sure to wear gloves because there is a tight nut to unscrew.
