Just looking for some opinions on this mower. How much trim does it have? Does it have the same IZT as a Hustler fastrak? Mowing a little more than 1 acre, would this be a good choice? Using a 15 year old 46/18 mtd tractor, will the zforce be faster? I can mow wide open with the tractor and mow in about 45 minutes. Thanks for any information.
