Posted this in the Hydraulic forum but thought another Orange machine owner might have some insight.....
Been awhile but I know where to go when I'm stumped. Lost all hydraulic function to FEL, power steering, and BH on my Kubota L3130. Hydro is working fine to move the tractor around. Pulled tractor out of the gargage (everything hydraulic was working fine), left it running and jumped off for a moment, heard an odd humming that stopped in several seconds. Went back and nothing is working. Jockeyed the control valves to see if anything was hanging and all feel normal. Cylinders will drop the implements as if the tractor is off when I jockey the control valves. I called the dealer service tech who was on the way out the door for some well deserved rest from the grind. He said it could be as simple as a relief valve or as bad as a pump. No visible line or other leaks. Anybody have an idea if this is relief valve related where to start and what to try?
Any help or ideas would be appreciated.
