I just bought a one wheeled sulky off ebay (not velke brand) and it makes my stripes look weird. It makes that single line in the middle and it just ruins it completely. For that last time for my lawns I actually had cardboard on the back of it with a brick on it, but that didn't do much. Does anyone have this problem as well? I'm thinking about going to the dump and getting a mud flap off an old truck. I'll put it on the back of the sulky...Do you guys think this will work? Thanks.
