Please help me decide.

Hello Forum. I am researching which ride on mower I am going to buy. I have it down to four mowers: the Toro Grandstand, the Toro Titan MX5480, 54", Toro Z Master 2000 and the Titial Z Master 6000. I am mowing 3 acres with a three rail fence that surrounds the entire property. New looks good particularly because of the 0% interest Toro is offering. I would go for a used one if the piece was in good shape. Please let me know if anyone has done a comparison of the units I mentioned. Any input will be greatly appreciated. Which unit do you like best.



PS: Since I am looking for a good unit should I be considering a diesel engine? Please let me know.



Thanks Very Much
