When I said "lawn tractor", I didn't mean a tractor that you could use for farming, it's a 54" front engine rider, weighs around 650 lbs. The addition of the offset mower really cut down my mowing time on the back yard, from roughly 1.5 hrs to just over 45 minutes. I've thought about a 7' finish mower for my utility tractor, but like you mentioned I didn't want to tear up the yard.
