Trying to get some of your thoughts.... First year starting up part time. Currently have 5 accounts ranging from 5000sq ft to 1 acre. I'm hoping to grow to 20 or so this year. Currently using a 2004 Deere L130 and a 15 year old Lawn-Boy (and a couple of new Stihl handhelds). I'm trying to figure out how soon I need to be looking seriously at a commercial z. It is so tempting to run out and buy one tomorrow, but I can't really justify it to myself (or my wife) for 5 yards, and we don't have the extra money to do so. I think the money and effort would be better spent on getting more accounts, but at the same time I don't want to get swamped and not be able to keep up. I'd like to set a 'trigger' that once I hit so many accounts (or so many hours per week or so much $$ per week) that I will go get my z. How many accounts do you think I can realistically do with my current equipment? Keep in mind, I'm solo and part-time... Eventually I'd like to get set up with a commercial 52-60" z, a 36" WB, and 21" WB to handle pretty much everything that comes my way.
