Back in the early 80's I had a big Bliss commercial splitter. It took 40 HP to run it at peak. It had it's own pump and ran off the PTO on a 3 point hitch. I think we were getting about $100 a cord then, and I charged $40 a cord to split at your house. I had to be able to get the tractor in the yard, a JD 2010 diesel. The deal was I would split and stack the wood where I cut it, not move it to the other end of the yard. The Bliss on a 3 point hitch would sit almost flat on the ground to roll a big block on it, then you could raise it to a comfortable height to work it. It also had a 4' wide tray so the blocks wouldn't fall off, and it cut in both directions. I didn't pursue work with it. My Dad owned a residential tree service, now and then people would call and ask if we split wood? He would ask why the tree company that took it down didn't split it. They usually said it was too expensive. So, he would say since they let the other guy do all the easy work, he would charge twice as much to split it, and they would go away. Once I got the splitter, if someone called, he would just give them my number. I did a few side jobs like that and made weekend money. The machine cost $3600 in 1980-81, and the tractor, used, was $2900. You would have to figure out what that is in today's money. I for sure didn't pay for them, but I wasn't trying to. With free adds on CL, FB, and such, and not being in a hurry or dire need, you could probably pay it off in time, making beer money along the way. When I retired from tree work I kept one of our stump grinders for about 10 years. It was a one man operation and I made a few thousand a year with it. Enough to go offshore 3-4 times a year and all of my hunting trips.
