I resemble that remark, lol, actually I have 5 acres to mow and I have worn the decks out on 3 mowers in 3 years, not trying to hijack the thread, but would I be better off buying a Ford 9N, used of course and a brush hog, than trying to find a smaller riding mower to keep up with the lawn and back field which is full of johnson grass??
This was used for 40 years to mow large yards (12 care yard for the first 30 or so years, and a 10 acre yard for 10 years or so) It was over 35 years old before the Wisconsin engine was rebuilt. It needs some work now, so I looked into replacing it. The local shop that services Wisconsins said that to replace my 12 hp Wisconsin and have comparable power, I would have to move up to a 24-26 hp twin cylinder for a new engine.

Yeah, I'm just going to have a Wisconsin guru rebuild it for me. This thing has exploded rocks, cut down tree stumps, and it just keeps going. It was built in 1966, and I'm finally tearing it down for a full restoration, and building a loader for it.
It has a 50" belly mount mower deck and 36" rototiller. Hydrostatic drive, and I mean real hydro, just drive, neutral, park. Forward and reverse are controlled with the pedal, no shifting, ever. This thing will pull a half ton with flat tires around a yard. I love it.
Edit: Beware of using the older tractors like the 9n for mowing, they have a live pto.
