Tractordata lists that models' total flow at 11.4gpm. Modern tractors that size usually have two pumps, one for steering (and sometimes the PTO clutch) and one for loader, 3pt and accessories. The steering pump is usually around 5gpm. That leaves about 6 or 7 gpm.
Your typical mid size log splitter like the Oregon "28 ton" splitter I have has a two speed pump that provides around 16 gpm at the high speed and with a 4.5" cylinder has about a 12 second cycle time. With about half the flow and the same size cylinder you'd have twice the cycle time, about 24 seconds. That's pretty long. You might be ok with that or it might drive you nuts. Many splitters use a 4" cylinder which would be a little quicker but not provide as much force. Also I think many splitters' relief valves allow a higher pressure than the usual tractor 2200 psi, which would also reduce the splitting force. Depending on the wood you split that may or may not matter.
