I bought a piece of property where someone had logged a bit 20 or so years ago. There was an Osage Orange or what we also call "Hedge" that had been cut down. The log is about 20" dia and about 5' long. That thing has to weigh over 400lbs. You can see where someone had started to cut it with a chainsaw, got about half way through and thought better of it. I just dug the stump out the other day. The feeder roots were not an issue, but the tap root tapered from about 18" dia. to about 3" over a length of about 4'. If that thing had not been on a small hill that I was leveling out, I would probably still be digging to get that out.
That stuff makes good fire wood with two exceptions, it's very difficult to cut and nearly impossible to split. A friend of mine has a log splitter made from the boom cylinder of a JD410 (I think) backhoe with a huge wedge on the other end, mounted on a 10" piece of I-beam. I have seen this thing nearly push the wedge off with a large piece of hedge in there. But...it does burn for a long time and burns really hot. It's good fire wood if you can get it. Cut it green, split it right away then let it sit for a while. It's also fairly impervious to rot and insects.
