I have a 1.5 acre lawn that is level but has lots of small dips and bumps. Nothing deeper than 3-5 inches, but it looks like it'll be scalp time with a mid-size wb. My dealer is pushing me toward a Exmark 36" fixed deck wb. I'm leaning toward the 48" floating deck wb to save time. Can any of you pros offer your advice? I'm not a commercial mower, but I'm sick of the junk normally sold to homeowners.
