I have a smaller yard than you. I shopped and researched and found certain characteristics that I felt I needed in a ZTR mower. By the time I got to the models that had the features I felt were required, it was a hop, skip and a jump to the Tiger Cat II which is what I had my mind made up I wanted if I could afford it. The dealer made me a good deal so I got CFO approval and did it. Is it over kill? Heck yes! But to me, it was worth it to get a mower that would last and keep up with my, let's just say, less than skillful driving abilities. Yes, the seat, oh my, the seat! My back loves me for this choice (granted, I had to pay to upgrade to the suspension seat as I got the 48" deck since there are 5 choke points in my yard that limited deck size). I only have one mow day on it so far, but what a difference coming from a 15 year old 40" Murray! Get what you want, if any one ask you why, say "Because I could, that's why!" Good luck!
