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.
