Just wanted to say I have never built a racing mower before but am in the process of one now, mostly I have built mud mowers. are there any mower race's in Minnesota?
  and if so can anyone help me with some ideas for something cheap but legal to the rules, I currently have a sears ST16 " No engine as I am parting it out", murray with 708 peerless transmission that goes to a rear axle I have locked " havn't tried this one out yet as it's in the garage" and a couple other MTD's I have for parts and an old Toro front engine rider with a 36" or 32" single blade setup kinda looks cool. don't know what to use for my base to build off of.
