Well, I put the eXmark flap on my Bob-Cat walkbehind and boy does it stripe! It's only about $17 but takes a while to ship. There's a 1/4 inch round thing molded in the bottom so I bought 1/4 threaded rod, put it in my drill and ZIP, ZIP it has some weight on the bottom. A lot less cumbersome than chains and won't wear or break the turf. Probably not as long lasting as rollers, but we'll see. There's two different flaps, one for gear drive (which I have) and one for hydros. If you love to stripe, you've just got to try this.
