Hydraulic problems

[fish2fry]

Kabota 2005 M9000 92 hp, The tractor is new to me, It is having problems with the Front loader Kubota LA1251, it's having a hard time picking up a full bucket of dirt and when that happens the steering freaks out and will not turn till I get the dirt out, we just changed all the hydraulic and engine oil and all the filters. I did have the front bucket disconnect and off the tractor, it like it has no power for lifting. what am I missing.
Thanks for any kelp.

Disconnect and reconnect your hydraulic lines. May or may not help, but sometimes they don't fully seat. It has helped others.

Sounds like you could have a pump issue.
But I would get the WSM (aka Service Manual) as it will walk you through testing it.

FYI: It's a KUBOTA, not Kabota

Has it been like this since you got it or is something that just started?

It was works right but never put under a load

Does that mean it was never tested with a load in the bucket?

In any event get a 3000 or 5000 PSI pressure gauge ($20) and hook it to the UP port on the loader valve.. Start the tractor and try to raise your bucket. You should see ~2000 PSI on the gauge.

If its significantly lower the pump or relief valve is defective or out of adjustment.

If you get adequate pressure but the loader struggles good chance a hose is miss-routed, not fully connected., or something down stream of the loader valve (rear remotes, backhoe. 3pt, etc) is blocking the pressure circuit.

I run it today got a big full bucket full and it had no problem, but before I run it I did a complete full extension on the cylinders, it may have air in it, would hot oil have a effect on my problem.?
Thanks for everyone for your help....
