I've been in business about 3 years with about 12 acounts. I never tried to acquire any more than that because also I work a full time job. I've been using a 48" Exmark Turf Tracer HP and I love it, but I'm planning to go full time next spring and feel like I will need a ZTR rider. At this time I don't really know what I'll be cutting but hopefully I will land some commercial accounts. I"m looking at the Exmark lazer Z 60". Is that an overkill? Should I go with a 52"? Thanks for the help.
