Lawn Mower Failure

I was using my lawn mower to pick up leaves on the hill behind my house. The self propulsion gave out. I had to manually push the mower. Then the rear left wheel stopped freely spinning. I asked my brother if I could use his mower. It is a small battery powered one. His mower started. But after a line or two, it petered out.

I called my lawn mower manufacturer. Had to prove I was the owner to register it and get warranty services. I called back and they said they would send an email with details on how to contact an authorized repair shop. They never sent the email. I got to call them again.

The only good news is that, while the rear left wheel will not rotate backwards, it seems to have come free to move forwards. It might still be a little sticky. But I can push the mower around and collect leaves. I hope they can repair the propulsion. There are too many hills on my property for a manual push mower. My machine is less than 1 year old.
