I have a homeowner version ztr and realize that it doesnt work good commercially. I have about 25 customers and the yards range from 5000 square feet to 3 acres. I am considering buying a 48" Toro walkbehind and trading in my ztr. I can only buy one mower and really dont want another rider until I can afford a really good one. Im wondering if a 48" will do me as an all around mower until I can get another ZTR. For those large yards I will get a sulky. Most of the LCOs I see around here only use walkbehinds. What do you guys think that only use walkbehinds. I like the look that the walkbehinds leave and very little tracks.
