Re: Splitters, My 22 ton from Tractor Supply (County Line) has been excellent, would not choose anything different if I had it to do again. They go on sale for about $800 ($1,000 normal price).
It is fast, it splits anything in it's path, and it goes vertical when you need it. I've done over 20 cords with mine and it has not needed anything but gas (and the 6.5 Hp Kohler is good on that also). Has a long run time.
The only mod I made, put a 3' long Hard Maple handle on it to move it around more easily. THEY SHOULD COME WITH ONE. It is a life saver!
