Ok,I cleaned and reinstalled the pressure relief valves on the hydraulic unit on my 445 long(similar to oliver).I put the brass washers as they were.My 3 pt is not lifting my 6 ft bush hog off the ground anymore.It had been steadily getting worse over time.New filter did not help much.Also hyd. Oil is cavitatating out thru the inspection cover plate.Is it worth checking pump pressure or should I just replace the pump?The small 3 pt adjustment lever seems to do nothing.
