What kind of blade tip speed do you have to have to get the "professional" look? I've seen entry level ZTR's 18k+ fpm and notice that seems to be in the same category of Exmark and others. Shouldn't I expect a very nice cut from a mower that cuts at 19k fpm, even though it's not a commercial machine? For example, I came across the Country Clipper today. For $3399, I get a 17HP Kohler with a 42" fabricated deck and lift out deck and it cuts at a higher speed than listed by Exmark. Sure, it's not a machine built to handle the rigors of cutting 50 hours/week, but I think for 5 hours a week, it should provide an excellent cut in the ZTR market for a brand new mower.
