I just demo'd a competitor's ztr which I found to be satisfactory. The one thing I keep hearing about your machine is the speed of the cutting, i.e. your machines cut grass "very" fast. My question is if all things are equal such as hp, width of cutting deck and number of blades doing the cutting, what exactly should I look for that makes your brand of ztr superior in cutting at a fast speed? Speed is very important to me but we all have to go slow enough to get a quality cut and I have an old Toro Groundsmaster which can get bogged down. I should say that I cut 3 and 1/2 acres of St Aug grassland in southern MS every 7 to 10 days. Due to the frequent rain and sun, it grows thick and fast. I don't know if I'm stating my question clearly enough. I intend to demo your brand so maybe I'll find out but what exactly is it that allows your machine to do the same job but faster? Thanks.
