I am just starting a Lawn Service Company and am overwelmed with all of the different mower brands. Does anyone have any recomendations as to which mowers seem to be best? I will be starting with a 60 inch rider. So if anyone has any recomendations for a 60 inch rider I would appreciate it. I have looked at Cub Cadet, Bob-Cat, Bunton, Exmark and John Deere.
