Change The Rear Wheel On Your Automower 450x, 430x, 420
After a few of years of owning your Automower you will notice the tread on the rear wheels will rub away. This will reduce its slope capability and your Automower is more likely to slide in wet weather.
Its nice and simple to change this wheel.
1. Remove the hub cap
2. Remove the nut with a 24mm Spanner or socket.
