I have fastened the controls temporally to the PT with C clamps and used it on some tough oak cuts of wood. It is working rather well. With a little more time and practice I am sure it will do even better. When I say 90 percent done I mean I need make a mount that can be easily taken off and on the pt. For the controls that is. I also need to paint it.
When I demoed it to Dad I lifted (with the upside down splitter) a large cut of Oak, moved it to another location, and split it into about 8 different pieces. All without getting off of the tractor. My guess is that when I have split a large amount of wood, it laying all over the yard, I will get the bucket, pick it up and take it to the wood pile.
