Hey why say it once when you can say it 5-6x? (kidding!). You do have to feel for the guy, although, ~200hrs in 3 years is beyond the scope of the RZT series in my opinion. I believe I read somewhere once where typical residential riding mowers are designed to last 250hrs. I've got a full 1.5acres to mow and only do ~30hrs/year. It would take me almost 7yrs to accumulate that kind of "mileage". Anything goes after 7yrs with a ~$3K machine IMO. Regardless, MAsZ, you should have the 4yr warranty on your RZT. You're set. Just keep in mind, the second you feel the SLIGHTEST difference in one of your hydros, you might want to consider an oil change on them which is very doable for someone with basic wrenching skills and access to this board.
