There was a good thread about Best ZTR's. I am also interested in the money outlay I would pay to keep the ZTR going. It sounds like Hustler, Exmark and few others are about the same quality,ride, depending on who you listen to. I just bought a 5 X 12 trailer from a guy who also has a commercial ZTR even though he only mows his huge yard. He mentioned it took 8 hours labor for the shop to remove the coil. Sounds like a tall tale to me but I have a Sears 44" rider I had before I started mowing part-time which only took me about 1-1/2 hour to replace a coil and starter. So what things go out on your ZTR and how much for parts/labor. I read somewhere (problably on this site) that spindles are aluminum on Exmark and go out quickly compare to other ZTR steel spindles. That may wrong what I just said but you got the idea what I am looking for? I'm sure the manufactures will not supply a list of things that go wrong and prices until something does go wrong. So the bottom line I'm looking for upkeep cost.
