Demo'ing one for the weekend. ZG127S model with the 27hp Kohler Courage Pro (SV840). Very impressed to say the least. I mow 1.2 acres. From start to finish it took me less than an hour, in ALOT of mud I might add. I have a couple of summers, 100+ hrs on a ZD331 so I was expecting alot out of this minature 'bota. Of course it's not the 331 but it is very well built. I don't have alot of tree branches hanging down so the ROPS wasn't an issue. When I spoke to the salesman about it, he told me that is one of the big complaints. The paddles are tight and the ground speed is more than enough. I mow at 3 3/4", I was cutiing about an inch and even in the very wet lawn I didn't have no clumping. I did check out a BB that a buddie of mine has, it wasn't for me. Grady The dry area of my lawn. The chute was off after the 1st pass.
