That’s cool.I'm just a home owner (where I use the Wright 36) and a Son-in-Law (where I use the Ferris).
My in-laws are in their mid 70s so their grass cutting production has trailed off over the years but the 13 acres of ex soybean field has remained...so I cut that with the Ferris, the suspension and suspension seat have been lifesavers. Local commercial mower dealer brought me a cheetah, a dixie chopper and a ferris to try out before I bought. They all had features I liked but the suspension sealed the deal for me. The ferris is a 2014 and has been issue free, has 200 hours on it now but they cut so fast that you really don't rack up the hours on one just being a homeowner.
I bought the Wright used, got a good deal on it because the engine was surging, ended up being an intake manifold air leak at the left cylinder head. Its a 2000 model with the fixed deck. That is ok with me because I only mow one yard with it. I put a mulch kit on the deck and use it at the main house, only half an acre but has lots of fences, gates, flower beds etc. It is a pull start Kawasaki 17HP, pretty simple machine, built like a tank, has 1700 hours on it now with no indication of any problems.
Im intrigued by the stand-on lawn mowers.
Looked at them before I bought my Gravely ZTXL, but they’re a lot more expensive than the sit-down models, and I also wanted to be able to pull a spreader or small dump trailer.
