first the alarm would sound and lock-out the hydraulics if the bucket got too close to cab, now it fires up no problem, but no hydraulics at all (boom,blade, track,etc.) I have checked the fuses, tried the toggle at the fuse box, the toggle under the seat(right-leg), all fluids are good, no alarms sounding, no problem engine-wise idle to full rev. any ideas on what to look at??? is there a relay switch to the hydraulic pump???
My guess is you need to reset the potentiometer, it is a safety device that prevents you from getting the bucket into the cab
Are any of the linkages damaged? The common one is at the pinned connection between the boom and the dipper stick.
