Actually, with 13.9 gpm, a 4" cylinder would be pretty quick. Rough calculation makes me guess about 4 inches/second which is faster than I would want a splitter to run. The real world is a little slower but with a real 13.9 gpm available, a splitter with a 5" or even a 6" cylinder would run OK.
Not fast enough for me. My splitter, which I consider about right for me, is about 7"/sec extend and about 9"/sec retract
Yes, you're right it is a 4" cylinder with a 2" bore... the model I picked up takes up to a 36" log and travel is 2-3" per second. It is a good old splitter and glides through the birch, ash and maple I've fed it. Pretty happy with the speed on the downstroke, just could feed it faster if it had automatic and/or accelerated return.
Longer stroke indeed slowds down the overall cycle. Do you actually split wood 36" long (over the normal 24") cause if not, its really slowing you down.
And 2"-3"/sec, you aint got 13.9GPM. either you arent running the tractor at rated RPM, or you you spec is wrong? Reverse figuring the 2-3" per second has you flowing somewhere around 6.5-9.7 GPM. Which would seem about right for some misleading specs. Alot of tractors have two pumps, one for hydraulics, one for powersteering, but list a "total flow" for the spec. Take off 4-6GPM for powersteering and what is left is for the 3PH, remotes, loader, etc.
Dad has a standalone splitter with 11-gpm 2-stage and a 4.5" cylinder. Puts it ~2.7"/second. I cannot stand how slow it is.
