After re-adjusting the MMM max height adjustment yesterday so the height knob would go into lock position again, I figured out how to do it w/o dropping or messing with the mower height BTW. All of a sudden I check today and the 3pt is 1/4 way down overnight. Its stayed up fine since I got it new last December till last night and I didnt touch anything hydraulic. Has anyone else had that problem where the 3pt just starts drooping over night? Lever is all the way up.
I only have a few hours on it since I did the 50hr hydraulic fluid change and levels are fine. Could there be an new internal leak that coincidentally happened after messing with it yesterday.
