I am going to buy a commercial ZTR mower this spring. I'm leaning towards an eXmark Lazer Z with a 60" cut. Does anyone have any experience with the 23hp Kohler? I don't want to spend an extra $1,000 for the 25hp if it's not necessary. Also, has anyone used both eXmark and other brands? And does anyone have a good solution for cutting bahiagrass in one pass?
