Past 6000 hrs this past winter - still starts & pulls fine (no rebuild yet). Just 3 major issues:
Governor had to be replaced/repaired, a plug in the cam shaft fell out dropping oil pressure (replaced the plug), and replaced a bushing in the hydraulic pump.
Starter needed a secondary solenoid to insure that 12V was getting to the primary solenoid/Bendix. Good on fuel, used to pull a IH 241 5X6 baler - tough assignment but it did the job! Added front end loader (Bush Hog) - use it as my primary feeding (bunk feeders) & utility tractor.
