Just a random contribution to the perpetual wood splitter threads....
but....
I recently traded up from a Timber Wolf TW-1 to a TW-2.
The increased robustness, and rapid cycle time has made a WORLD of difference in splitting off the log pile. DAY AND NIGHT! for one or two person operation. (second person clears the splits away from the run off table.)
IF one were evaluating a splitter based on performance, Comparing the TW-2 specs would be a great starting off point.
It's not a processor by any means, but the unit is capable of working a young man to exhaustion (I'm not a young man)
I use the tractor and carry all to bring the rounds to convenient height when the logs are large. and a pulp hook for the lesser stuff.
The only thing I would add to the unit (besides a four way and the run off table) is a retraction length stop to trigger the kick off, and stop the push block at the cut length or the rounds. I've seen "videos" of efforts to this end that result in shearing off the cylinder threaded end, So, I just live with it until something comes up. Waiting for the retraction and stopping at the desired length might add 1 second to my cycle time. I often can use the rest ;-)
