What ii thought was a Bolens Husky 813 is really a 613. I was able to get out in the garage for a bit today while my knees felt half way good. I lubed it up a bit and got the brake lever loosened up so now the brake works. But for some reason when the brake is on the tractor still wants to move. I checked the belt and its loose so not real sure way its moving ( Any ideas ?) Thats about all my knees can take for 1 day.
