Looking at jumping into a 72" ztr this spring. I cut 5 acres at least once a week and some times more depending on how much it's growing. I keep the bermuda at 2 1/4 and 2 1/2 inches. No there is no sprinkler system installed (I wish there was). So I am leaning towards a Bad Boy 72" mower. I'd love a diesel but I think that is out of my budget this year so I am looking at the gas models. I have a choice between a 27 HP Kawasaki and the 35 HP Vanguard. Is one better than the other and if so why????
