3720 Weak Hydraulics

[JDENIS34]

I have a 05 3720 with 683 hours. Today after moving some logs I noticed the loader(300CX) would not go all the way up. It was stopping about 2/3 of the way up. Also It does not have enough downward pressure to lift the front end off the ground.
The hydro filter and fluid were changed about 300 hours ago. Any suggestions on what to look for would be appreciated.

Unplug, clean, and reseat all four of the QD's (quick disconnects) for the loader, this cures most of the "my loader won't xxxx" problems.

Thanks Kenny. That was it. One of the QD's had been pushed back but was not enough to leak yet.
