These wheels fit my Hursqvrna HU725AWD. My 20017 mower needed more than 2 wheels but the other one isn't that bad. I didn't know this when I ordered and thought i was going to have a spare. Check all your wheels while you have the wrench in your hand. This was the best deal and i really can't tell the difference between mine or these. BTW my serial was 961450017 03 . The space is intentional.
