When I first saw the Bad Boy mowers at TSC two years ago, I thought that they were the most substantially constructed mowers that I had ever seen. And, I still do. I started looking at the ZTRs about 3 years ago when my 10 year old MTD lawn tractor begin to break down almost weekly. I've looked at most of the ZTR mowers from small residential machines under $3000 to bottom line commercial units at $7000. I only need the mower for about a 2 acres area around my house. I 'll use a tractor and shredder for anything larger. I somewhat narrowed my choices to 3 mowers - the Bad Boy 54" (residential) , Toro MX5060, and the Kubota Commander 48". However, all the mixed reviews on the Bad Boy turned me away from them. The Kubota looked like a nice machine and the Toro looked less substantial that any of the three. However, I ended up with the Gravely Pro-Turn 52 which was not one of the 3. I've only had the mower 2 weeks, but so far it has performed great - also very fast for a lawnmower . But, I still think that the if the Bad Boy mowers perform as well as their surface appearance presents itself, there would be no better mower on the market for the money.
