Thanks to everyone who replied and the wealth of information on this site. I just purchased a 48" Scag WB Belt Drive for a very good price. Got everything new with the 48 mos. 0% financing and couldn't be happier.
I was between the exmark and the scag and it came down to the velocity deck and the dealerships service. The exmark was a good price and my scag dealer actually beat it. Mowed my lawn yesterday and the time went from 2.5 hours down to an hour. Very satisfied.
