I've been mowing professionally for quite some time now, and my dad and I just started our own mowing business. I've never had any problems with mowing with zero turn riders before, but our new mower which is a Cub Cadet M60 tank is leaving bad tire marks/ruts in the yard when I do my 180 degree turns. I've never had this problem before with any zero turn riders, and I know the yards are still a little soft in the spring, but does anyone know whats going on? I know I am not going too fast, because I creep through turns and it still tears the grass up. Does my mower have too much rear end weight? Is it my (the driver) fault? I need to figure this out because I bought this mower thinking that I would be able to stop and turn on a dime and mow to my hearts content. But right now I have to take extremely wide turns and sacrafice that clean, crisp, striped look that I always could do with other mowers. Anybody have a M60 Tank or know what my problem is? Any help would be fantastic.
