Are there any residentially priced machines that have commercial FPS ratings on the blades? My funds are now limited to a residential machine due to some unexpected bills. So, I'm looking into the residential market for a ZTR. The thing is, if the blades are spinning at the lower speeds typical of residential machines, then I'm guessing that the higher ground speed of a ZTR over a comparably decked tractor would be of little use (manueverability aside). You can't mulch well, if you're passing over the grass too quick for the blades to recut the same grass a second or third time. Any thoughts as to which resi machines have the higher blade speeds? Also, if there are any, does anyone know how much trimming their decks will allow? I looked at to Cub Tank models(when I had more funds), and the bigger the deck, the wider the rear tires...to the point of almost no trimming ability.
