hello new guy on here.. looking at buying a new F3990 72inch with ac cab yes I know they are $40K but its hot and dusty out lol.I got a few ZD331with 72 inch mowers and love them. Have any one moved up from the zturn to these front mounted mowers. I'm a right away mowing contractor so we don't do yards. I do a lot of subdivisions and will have to get use to working around mail boxes. Any opinion may be helpful thanks.
