Hey, That second pic looks like one of our local tractor shows. Washington crossing to be exact.
The first splitter pictured I have seen in action, thoughprolly not the same one. You have to be nuts or mentally challenged to operate it though as it spins continously at about 100rpm while you just walk up to it and place the log in and WHAMO the log halves fly about 5' each way.
They were banned at the bangor(PA) show due to injuries.
The third pic is simply an ond hit/n/miss engine thats been *******ized. Not a bad idea though.
