Yes I'm using the loader controls, the bucket dump control to be specific.

Does anybody know where and how to adjust the relief valve setting (correct term?)?

When I bought the tractor I talked to the dealer about installing the Hyd remotes on the back but they wanted something like $550 and I didn't think it was worth it for a simple log splitter that I bought on Craigslist for $300.

Determine where the reliefs are in the system, and see which one ( if you have more than 1 ) is opening.. You may have one on your FEL spool.. or perhaps on a divider block.. just take a look.

From your description you have a 4" cylinder. That gives you about a 12 square inch pistion area. This area times your pressure will give you the force of your push - about 20,000 pounds. I have an identical piston size on a splitter with relief set at 2200psi. In 20 years there have been only a few logs that it hasnt gone thru on first try, and none that didnt split on retry. I have split up to 40". Its the smaller ones with knots that give trouble. I think youll be happy with yours when you get the pressure up.

Thanks for all the great feed back, I'm close to getting back to this issue and I'll provide more details and some picts soon.

Funny you should ask this question. I just purchased a 0-3000psi gauge to check the pressure on my tc33d. I'm not happy with the loader power and I've been looking at the manual and it says, if you have the single spool valve kit, the pressure should be 2130 + or - 70 psi when connected to the diverter valve. It also says that if you have a "double - spool remote control valve", the pressure should be 1750 psi at the high pressure tube while moving the control lever to the lift position. It sound like the 1750 number is comparable to your reading. I don't know the reason for the different pressures readings. Both test should be done with fluids warm and tractor engine running at full throttle.

I didn't answer your question about the maximum safe pressure because I'm looking for the same answer. If I don't get an answer, I'll raise the pressure 10% over specs. They should have a built in safety factor much greater than that.

Regarding your question about how to increase the pressure: the diverter valve is located on the lower, rear, right side of the engine where the lines to the loader control valve originate. On the bottom of the valve there is a plug and as you remove the plug you will fin shims that push against a spring. By adding to the shim thickness by .004 inches, you will increase the pressure by 51lbs. As for the loader valve pressure adjustment: you should find an adjustment screw with a lock nut attached to it. This should be located on the top of the valve housing next to the the spools that the handle is attached to. Turning this in should increase the pressure on the reliefe valve, in turn increasing the output pressure.
