I've plowed before and some of my customers from plowing are interested in Lawn Mowing, So I've been looking around for some Equipment and i've found some. So my question here is what else do i need like what kind of insurance do i need and do i need to get a special license here in new york? Im pretty much will be doing residential yards. Also how do you estimate yards by how many square feet or how many obstacles are their? The equipment im looking to buy is a Toro 36"Wb hydro its new for 2600 and im looking at a 6' 4" X 12' trailer thats 1300 new. and i got trimmers and back pack blowers already.
