I have been learning a lot about my 2004 New Holland TC30. These tractors are different from others, I also have a 2000 L2500 Kubota.

(2)- I'm referring to my 2004 New Holland TC30 4x4 with 7308 loader.
(3)- If your float mode keeps disengaging and the loader is not lifting as it should. The PSI to your loader is to low. My TC30 joystick was jumping out of float mode and was not lifting a full load of dirt. Check your valve pressure at the joystick , take the cover off, facing driver there is a nut with a allen screw in the middle of the nut, this is where you increase or decrease psi. Attach a hydraulic pressure gage and hose to any of the boom or curl quick connects and check your pressure. my pressure was very low at 1,000 psi, factory is 2,250 to 2500 I reset mine to 1,900psi as I don't want to take a chance of breaking front axle or breaking the tractor in half, which does happen. After setting pressure the float mode when engaged stayed engaged and loader lifted much more weight.
(4)- When you install the hydraulic gauge to your joystick valve body and engage, the hydraulic gage will bleed off, I went thru 2 gages before I decided this was normal. You are thinking the valve body is bad, so did I so I put a full load of dirt in the bucket lifted it 4 feet off the ground and next morning it had not moved a millimeter. I'm still learning by trial and error.
(4) Some of the TC30's have down pressure that will lift the front tires off the ground and others lift off the ground by curling the bucket.
(5)- If anyone with a TC30 has anything to add, please do so.
