Just a closing comment. We got 13" of March madness day before yesterday. That stuff was soooooo heavy. My Kubota did fine, but it was all it could move. Young guys get ideas of providing services for folks, to make money. As far as it goes, that's a fine ambition. That said, I think he got good guidance, if he read it. Don't make commitments to paying customers that a Sears lawn/garden tractor just cannot keep.
I set up my boys in service providing. They did well and paid me back for my investment in them. I'd do again, for the right young man in a heartbeat.
