Xring100 takes him about 15 mins. to cut 2 cords into 18" blocks for his stove and he can pick out a size so there's not splitting involved.
KiwiBro he's had up to 6 machines at one point but now just has the 1 and does very well. He cuts by the cu. meter contracting from logging company's with contracts from 100,000 to 500,000 cm logging shows.
Hutchman just the heads for those machines ( wartah ) he uses are $250,000 and to avoid fines from the mill logs must be cut to the 1/4" in length and sorted. I can understand why more loggers don't own them dangle heads take some getting use to to operate and are very easy to damage. The computer alone is $10,000 it records ever cm cut as well as keeping the length perfect.
I was visiting him a few yrs. ago when I took these picks we went to the site to service the machines before they were low bedded to the next block. I have a video so you could see how fast they process but don't have any idea how to load it.
