personally, I would choose that snapper over a walk behind, just because it can fit anywhere a walk behind can, and it can mow big lawns at like 8-10 mph. There is the cheapest commercial zero turn I have found http://www.badboymowers.com/view/zt-commercial-pricing
this has the cheaper gear pup as one unit, but on my toro it has lasted 1000 hrs. Then this is the bottom of there heavy commercial line. http://www.badboymowers.com/view/pup-commercial-pricing
. Its comparable to $9,000 machines or $12,000 John Deere's. I do like this brand. They are bigger in the south. Very dependable.
