I own a Weed eater one riding lawn mower for two years and it does a great job at cutting grass. While cutting grass today my lawn more would not move forward or in reverse. I tried using the lock on the back to make sure that it was not locked. The back tires seemed to me like they were locked in place so I to pull the lawn up on level ground. Then I tried using the mower to cut grass, it seemed that everything was fine. I mad two passes and the back tires seemed to have locked up again. I could not get the mower to move forward or in reverse. I finally got it on my trailer & made it home. I then jacked up the lawn mower to see what I could find wrong. The tires then started turning backwards & forwards. So I took the mower off of the jack & cranked it up so that I could put it away. The mower was moving very very slow going in reverse & forwards. The mower started shaking & making a clanging noise. I also noticed the bracket on the back by the tire was a bit bent out wards. So can anybody tell me how to fix this issue? If there are any pictures of what I need to look for please tell me where to find them.
