well i came up with an idea. i had a piece of plywood. o put nails through it so they stuck out the bottom. i nailed 2x4s along the front edge. im going cut the grass real low. and the tie a chain to the 2x4s and put 10-20 lbs on it and drag it around the track a few times.then do some tuch up by hand how do you think it will work.
