Right now I’m starting with just a 21” Troy-built push mower and a ryobi string trimmer. These are what I already owned. I also recently acquired a 50” cub cadet riding mower that come from a small lawn care company with almost 400 hrs on it. Unfortunately I don’t have a trailer and can’t get it in my truck. Can I realistically start with just these? I also may be able to borrow a Dewalt battery op blower until I can save and by my Own gas blower. Also what things other than mowing could I do, like mulching, as a 16 yr old 1 man op? And how to get first non friend/family customer?
