Right now I am fact finding. A friend is a contractor, and I occassionally do post holes for him. He asked if I had a trencher, as he could often use one on jobs, and would sub the work out to me if I wanted it. There's fair potential there for the capabilities of a compact tractor with a loader, scraper, auger and trencher...
Basically, I have found that my tractor is perfect for my home application, and does everything I ask of it. But, for other applications, I am low on HP.
I could upgrade, but mine is paid for... I could not afford to upgrade without payments right now, and would prefer to stay away from that.
