The reason for the wheel in rules is for safety, no blunt points to the body incase of an accident, and for the appearance of a mower. In my opinion mike, and all the others using it are very creative to find a way to fit the rules, and also fit what works for them. I've seen these in action and I think it's very impressive! I've never tried it, but I'd jump at the chance to!! Even if it didn't work for me, I would not slam or cut on the guys that have it. It's safe, and it looks original, and it works for them. Thumbs up guys!
