I was operating my in-laws T300 with grapple when in the middle of loading all the hydraulics stopped and the hydraulic light started flashing. The loader won't even lower but it does move slightly up and down. When it happened I think the bucket tilted down and the grapple arms opened fully. It also acts like its in park. I am going to put a new hydraulic filter on. They may have never changed it before. It has had problem previously with the loader tilt or lift pedal sticking to the floor randomly and sometime the grapple sticks until you restart the auxiliary hydraulics. Please HELP!!!

Changing the hydraulic filter will solve nothing. All 4 lights on the left dash on? All need to be to work. If you are not getting a seat bar signal, the unit will not unlock. If you press the traction over ride button, the brakes should release so you can move it. Any warning codes. I'm thinking the belt is fine since you say it try to do something. I'm pretty sure you have an electric problem. For grins and giggles, check all the fuses.
I figured changing the filter wouldn't help but I know it needs to be done. All four lights were on and I didn't notice any codes but I can't say I was looking either. I presume they come up on the display in the top left corner. I will try to check fuses tomorrow. I am sure I can find them but where are they located? I have little experience repairing skid steers but am a season tech. Kind of groping in the dark without a manual. Any idea why the controls might stick randomly? It's been doing that for years but I haven't had time to sit and work on it. Thanks
Does it still drive? just wondering if the main drive belt could be slipping.
As for the pedals being locked out. Are there any leaks on the control block? if so, what can happen is the oil gets into the solenoids that unlock the pedals. When this happens, they don't work properly as they are full of oil.
The fuse box should be between your feet just above the chain case. It could also be on the back of the ROPS below the window.
No does not drive but it loads up when you try. All the fuses were good but I feel nothing in the pedals now. It is throwing a code for extremely low charge pressure. Any thoughts? Is there an online source for a service manual?

Well I finally got to do some checking and there is no pressure at all from the charge pump! I was going to check the relief valve if I have an Allen wrench large enough to remove it. The belt is turning and looks ok. It seemed like it was awful sudden for a pump to just quit when it seemed plenty strong before it stopped. What else should I be checking?
I have seen the pulley spin on the pump shaft. Also there was a certain serial break for the T300 that the pump shaft snapped between the sections.
