MX5400 HST third link issue.

I was running my bush hog today and when I got it back would not lower.
The front end loader and top link works.
The hydraulic site glass is full.
I cannot find and obstruction that would stop it from moving.

Is there a three point speed control knob on that tractor? If so, it may be set to really slow down or locked so it can’t move down.

I set my mower height and lock it with that knob on my tractor, so maybe someone did that on your’s?

That was it. Crazy that it worked all morning like that with out and issue.
Thanks for the help.
