3 pt won't lower

[runningbird-HT]

hello
I have a fx20 that has been great the last year. went out the other morning and the box blade will not lower. If I leave the tractor parked for a couple days it will leak down some, but soon as I start the tractor it raises right up. no mater what position the lever is in. the knob under the seat is in the correct position and I have tried screwing it in an out but no difference.
anyway thanks for any Ideas!

Sounds like the lever has become disconnected somewhere. Follow the parts movement.
