Joe, I had a 38" Toro Timecutter in 2004 to 2007, never back to the shop and never needed any repairs, but I sold it when I needed to help some kids and had to be able to get through 3' gates. So I went to Toro's personal pace walk behind in 2007. They no longer have the 38" one. But this year, Toro has come out with a 32" ZTR and I bought one in late March. I like these Toros, but haven't used one long enough to know how well they'll hold up. I've got about 13 hours on this new one.
And no experience at all with Simplicity.
