I have a sweeper problem. The Tread on the ground drive wheels is gone, long gone. Tried pounding roofing nails in being careful not to nick the drive gear. FAIL. Found a youtube on retreading push mower drive wheels with bicycle tire tread. They stretched it tight and ran some hex head sheet metal screws in to hold it. I was wondering about adhesive. One guy used Permatex Orange Adhesive whatever that is, it was orange, and mentioned Amazing Goop. I found a tire cut repair thread on YT that said use 3M Windshield Urethane 8609. Anybody else got any ideas, i can't swing a new sweeper right now and tis the season. Also anybody got a way to pick up black walnuts I have a 150 yr old tree that has a bumper crop every year. I know I can solve this with a chainsaw, but I like the tree just not the back breaking clean up. Help?
