We have an M4900SU (4WD) with a Woods 1020 loader.
1073hrs on the meter.
The tractor was partially submerged 6 months ago. All filters and fluids were changed. Last week, we changed fluid and filters again. The hydraulics were a bit milky.
We hooked up to our bush hog and mowed for about 2.5hrs with NO ISSUES. Suddenly, during a 180 turn, the steering stiffened up and a loud squealing noise was heard in the front. (sounding like engine belt).
Now, the steering and loader will not operate properly unless the RPM's are above 1200. Could this be a pump issue or relief valve? Is it possible to set the pressure on the relief valves?
Thank you in advance for any suggestions.
