CONCERNING A '93 FORD 7740 3-PT. HYDRAULIC LIFT. I SEEM TO HAVE PROBLEMS LIFTING A 10FT. ATHENS HARROW WHICH WEIGHS ABOUT 1800LBS. THE TRACTOR LIFTS VERY SLOW IF AT ALL BETWEEN 9-1300 RPMS. NO PROBLEMS AS LONG AS TRACTOR ENGINE SPEED IS ABOVE 1400 RPMS. HYDRAULIC FLUID IS FULL, FILTER IS NEW AND THERE IS NO ASSIST CYLINDER. ALSO, THE 4 REMOTE VALVES ARE IN THE NEUTRAL POSITION. IS THIS NORMAL TO HAVE TO HAVE THIS HIGH OF RPM TO LIFT THIS KIND OF WEIGHT. THANKS FOR ANY HELP.

absolutely not. You have to have hydraulic problems. My 92 has 3 filters. I changed each one at a time but did not recieve top hydraulic performance until I changed the 3rd. I would recommend testing pump output if you have changed all filters. Also check fluid while tractor is running and check for cloudiness. Might indicate an air leak in your system.
