I actually have the whole lawn mower. It doesn't run the starter and battery are missing. I could buy a new starter and battery but, I don't want to spend $200 on a mower I can't use (yard isn't big enough) or get my money out of if I sold it. So I could actually use the entire lawn mower frame if I wanted to and just cut it up with the sawzall. Would also give me a great place to mount a smaller engine but, I think the frame would be too heavy for the bike.
