Just put the finishing touches on this one for my boys today. It is an MTD Mud Bug chassis that my uncle gave me. He picked it up at a swap meet years ago and never put it together. The body/seat is long gone and trying to find an extra is just about impossible. I welded a simple bracket and put an old lawn tractor seat on it. I put a 212 on the back and wired up the throttle, brake, kill switch, etc. It needs a new belt on the CVT, but it pulls my 10 year old around the yard with a big cheesy grin on his face, so I guess it does the job.
