Buying first zero turn for about 1 acre. So far looked at Snapper, Bad Boy Maverick and Kubota Kommander. Really like the Kubota but can't decide on size. 42" would seem to navigate obstacles (several tight trees, gate, etc) but the heavier and wider 48" would seem to handle the slope better (15 deg prob). I like the better hydros in the 48 but it's a Kohler and the 42 is a Kawasaki (seems to have better reviews). Any help is appreciated.
