Shibaura SP1540 Hydraulics Stuck Up

[franklyspeaking]

My hydraulics are stuck in the up position with the bush hog attached - most of the tractor weight is on the front wheels and bush hog wheel. I see a slight movement down when I actuate the joystick down, and then nothing. The up direction then moves slightly up and then strains (full up). I checked the downside of the control valve, and I get 12 volts when the actuator is down. Appling 12 volts to the down side yields nothing. The manuel over-ride switch also does not work. The up over-ride makes the system strain - seems okay.

Is my spool valve toast or am I missing something? It does seem that there could be something preventing it from going down, but I can't see anything? [img]/forums/images/graemlins/confused.gif[/img]

Is there anything I can do to get the hydraulics to let the tractor down?
