Hiya,
The specs say 948 PSI & 6.5 GPM flow, single circuit. While that's enough flow to run the splitter "sufficiantly slow enough to be productive" the pressure is way too low. You would have a slow, about 8 ton splitter if you ran the tractor at rated RPM. You also need to check if the 3pt on the 748 will raise high enough to get the splitter frame off the ground and it has the capacity to lift it as it does stick out a bit from the link pins. (Also, make sure your 3pt arms are long enough to keep the stands legs from contacting them as they get closer to the tires as you raise the 3pt up.)
It's not cheap however since the x748 has a rear PTO you may want to look at getting a PTO hyd pump and using that to run the splitter. You'll need a tank for at least 3 or 4 gals of fluid, a PTO shaft and some welding skills. The TSC 3pt frame would make a great place to weld in a flat plate for the tank and a mount for the PTO pump. Add the hoses and a suction side filter and your good to go. I'm sure someone has done this before, look in the Hyd, projects or build it yourself forums here and use the search function.
I have run the TSC splitter on a 2520 and a 3320, both of those have enough flow and PSI to let you live with the splitter if your not in too much of a hurry. I will be making a self contained setup like above hopefully this winter.
