Kubota LA525 front loader not working properly. Lifts and lowers slow and doesn't lift as much weight. None of the seals look to be leaking an at times you can hear a hissing sound from the control panel as if it trying to lift or lower when tractor is just ruining. Also seems to make the tractor run hot. Could cheap hydraulic fluid cause this, or does anybody know what else the issue could be ?

Your priblem is not the coil. That is classic symptoms of power beyind citcuit obstruction.

What model tractor is this and do you have any of the following on the tractor?
  1. Loader 3rd function
  2. Remote valves
  3. Backhoe
  4. Any other hydraulic accessory

We had a stump grinder. We removed it but the hoses/ connectors are still attached just capped off

That sounds very suspicous. How was it connected to the tractor and how is it "capped off". Pictures of the tractor side hookup would be helpful.

Our local kubota retailer hooked it up then we ended up letting it go and they removed it

Looks like you have one factory rear remote with some sort of electric addon. I am going to guess its a diverter used to switch the remote between lift and swing cylinders on the grinder.

Check the lever on the factory remote to make sure its in the middle (neutral) position.

Also put the 3pt lever in the full down position and recheck loader operation.
