My bobcat skid steer will not lifht any weight with the bucket it will move emty but really slow all others work fine

Question edited for clarity.

If it was running before with no problems, I switch or controller is unlikely to have suddenly failed. The most likely answer is the the mouse wiring repair has caused the fault, bad connection missed connection, misplaced connection.

You may be low on fluid...the check valve keeps fluid from "back flowing"

Hi Joseph:
Usually hydraulic components will "self clear" any air in the system just by trying to cycle through the functions a few times.
Have to ask the question............
Did you remove and replace the hoses one at a time, or did you take them all off at the same time?
The reason I ask is............ Could there be a remote possibility that any of the hose onnection locations were switched?

Since you didn't specify, I'm taking a guess it's making noise only when you're driving it, not when sitting an operating the bucket or aux. hydraulics. You have to describe the noise, is it a whine, groan, high or low pitched, grinding, crushing marbles, what? Describe the sound.

Depends what model you have. I suggest you do a Google with 'bobcat skitsteer problem'

I know on a bobcat 773 there are 2 spool lock soleniods. They are on the front of the bucket control valve. They literally lock the valve by a spring loaded pin that goes in a groove on the spool. When they get juiced the pin retracts and that spool can move. One for lift and one for curling the bucket. Check the wires coming out of the solenoids. Unplug them one at a time and see if the code comes right back. That should narrow it down to which one is bad. I changed both but compared ohms.

On my Bobcat it's low hyd fluid.
