My Kubota hydraulics is getting wimpy. I can barely lift the front wheels off the ground when I curl. I used to be able to lift them up and slide the mower under the wheels.

I recently changed out the fuel pump and filters. In the early Spring I had a service tech change out the hydraulic fluid and hydraulic filters. A couple of weeks ago, I noticed the lift pressure low. I have to run the RPM up to just lift the empty bucket.

The level is good and the fluid looks okay. It was a bit foamy but no more than usual. I know there is an internal recirc relief that regulates pressure but I have never messed with it. Where do I start?

Start by using a 3000 PSI hydraulic pressure gauge to measure the pressure coming to the loader valve.

Can you point me in the right direction. Where to purchase a guage and where to tap in?

Here i a a gauge -:there are plenty of other sources. Get a quick coupler to match the ones on the loader and use it to plug the gauge into one of the loader ports to measure pressure.
