Hello, I am new to the ZTR purchasing and all the research I have been doing is quite time consuming and confusing. I have a 2 acre yard mostly flat not very smooth. I have been looking at the gravely zt xl 48, the hustler sport 48, and the exmark quest 50. The main thing that I have been looking for is the fab. deck, would like the serviceable hyros, and a kawasaki motor. My max budget is 4500 but with the right advice I may be able to squeeze 5000 out the door tops. Any advice between these or any other brands or options I should focus on would really help before my wife kills me with obsessing and researching these machines. In advance thank you for looking and for any suggestions.
