I am trying to start up a lawn care business to help fund our family's adoption. I am looking to purchase 3 things. 1) a mower: preferably a 51' or 48' Exmark walk behind (I have an Exmark dealer close by). I've been told a walk behind is what I need to start with and then if I have the need move to a ZTR. 2) a blower: I am looking for a Stihl BR600 3) a good commercial weed eater Thank you for your help.
