Got the old Stickler out of mothballs,still works great! For those members not familiar with the Stickler,It is a screw type pto wood splitter. I run it 237rpm PTO speed (1100 indicated) seems to be a good speed for splitting.I've split wood up to 12' in diameter. The length I keep around 3-4' .Wood species also determines how well it will split. You simply roll or carry up the wood to the splitter screw,hold the end near the screw up off the ground,and let the screw auger in about 12''-15" from the end then stand back let-err screw. I keep a small axe on hand to cut stringers.
