I have a 753 bobcat front loader and I'm having trouble with my hydrolics when I raise my boom up. It won't come back down, when I tilt my Buck it down it won't come back up

Could you have the aux. hyd's on?

Does that bobcat has some sort of regeneration valve ? It puts oil in the cylinder but doesnt let it back out. You can extend both cylinders but not get them in anymore, pushing them out requires more oil than pulling them in because pulling means the surface of the piston rod misses. You have a return flow problem of some sort, probably in an additional valve like a regeneration valve.

One of the auxiliary solenoid stems is stuck "on".
