I am new to the forum and new to wanting to build a racer. I had just retired from the Navy. I was a welder/ Shipfitter in there and can build just about anything when it comes to metal. I have gotten 4 free lawn mowers so far from the local area need advice on which one would be a good race mower to build. I will post pics tomorrow when all the rain stops around here. I have a Montgomerey Ward around 1990 that has a 12.5 b&s 7 speed thansaxle, A toro rear engine 11hp B&S , a Murray 14.5 B&S hydrostatic drive and am picking up an Older Murray 11hp tomorrow. I thought the Montgomerey ward would be a good one but have read that 7 speeds arent any good for racing. But stock its the fastes one I have.
