I have had that exact same machine with same additions for about 8 years and it has been flawless. Need to add conveyor to realize the potential of it as you will get buried in splits.
If I didn't just buy a "new for me truck" and a brand new arbortech body, I would be all over this splitter, it is exactly what I would want. I've been looking at a new tw-2hd, and almost pulled the trigger on it.
Yours is a step up in grade, longer stroke, both wedges etc; and it the price of the new stock 2hd with just log table and 4 way.
