I can only speak from research, on this forum and personal experience. I have about 3.5 acres of field that I mow, not really turf. It is very rough in some parts. I bought a Scag Liberty Z and could not be happier with my purchase. Thing is built like a tank, has been thoughtfully put together for things like oil changes, has dual hydros, in lieu of single hydro. 2.5 years and I just turned over 50 hours, I did put a suspension seat on it. Expect this will last me most of the rest of my (mowing) life, am in my low 50s. I have a good dealer close, but have not needed them for anything so far, except purchase, delivery and oil filter. FWIW
