help with 99 tn75s 3pt.

my 3pt stopped working all of a sudden. I was mowing stopped to get a bite, turned the tractor back on and my hydraulics wouldn't lift anymore. I checked the oil, filters, etc. PTo works fine, I messed around with it trying to figure out what might be the problem, and broke a lever thats on the side of the 3pt arms( never could figure out what is was used for) but, the bolt holding it broke. i was hitting it with a hammer , trying to loosen it up( i know it wasn's the best idea) trying to figure out what is wrong brefore I have to drive 4 hours to the neirest compitent mechanic, I live in mexico, so this is the norm here. lol:laughing:

My guess is air in the hydraulics. I had same issue including FEL for about a year. Bled the lines and worked for awhile and then stopped working. Got tired of bleeding the lines so I changed the hydraulic fluid. Haven't had anymore issues since. Don't know what the cause (filter, plug or fluid) was but changing the fluid fixed it.
