Purchased one of these splitters that ran off a tractor PTO. Worked great but there were times I had to cut the log off with a chainsaw. Tractor did not have enough power to split the log but enough to bury the tip. Two years after I purchased the splitter, I received a letter telling me to break off the tip and not use the splitter anymore. Sent a letter asking for return of my money but no reply. Did not expect to get a reply but sending the letter made me feel better. The splitter was not very good at splitting stove wood. Some logs would just become propellers!
I heard they even made some of these splitters to run off the rear tire of a car.
