[QUOTE="Kermode, post: 38694, member: 3305"] Need more info. Will the boom pedal move or is it stuck? Could be the lock out to the pedal that isn't disengaging. Put a block under the bucket and tilt it down. Will the boom move up or will the machine lift off the ground? if the boom will float then maybe the float control is stuck on. Have you lifted the cab and looked at the control linkage? Maybe the linkage came apart. Too much hyd oil can't be the problem. Too little can be but not too much. I suppose the control valve could have completely failed and be bypassing but I doubt it. It could be jammed maybe. I have seen bits of o-ring jam control spools. Usually electric ones, Manual ones have enough force to open and close them, o-ring or not. The same pump runs the tilt and lift hydraulics so I doubt its the pump. I can't think of anything else off hand but I bet others can. [/QUOTE]
