My tracotr lost steering and remotes while operating it earlier this spring, worked fine then got to end of field no steering and not able to lift the soil finisher. eventually I was able to lift it and turn on the end but very limited, filters were pulled and changed and rear sump was checked and fine. I am told they also have a front sump ? Is it possible to have a broken tube inside the transmission that feeds oil to the pump ?

Does the tractor drive normally meaning the clutch and hi-lo 2-speed work as they always have?

This would mean the transmission pump (and pickup tube/screen are functioning normally and the issue is in the main hydraulic pump, possibly something in the pressure control valve.

Is there a manual destroker on the main hydraulic pump?

If so, destroke it and run the engine for a short time, then put it back in atroke and see what happens.
