I'm 48 and do around 40 yards/week about 50 over a two week period, this year for some reason was the worse for employees it started out good but went down hill about mid season guess when it got hot they all went to crap. I'm back cutting by myself for the rest of this season anyway, I advise a helper also, at least part time. Good luck. Your two top priorities should be marketing and proper bidding, sit down and really get close with the calculator. You'll quickly see why you can't cut for $25/yard, like some of these guys are trying to do.
