Hey guys im new here and i just wanted to ask a question. I have a ford 6640sle and here lately when i push the clutch in to take off it jumps real bad especially when it gets warmed up or if i am pulling the hay baler. I have not took it anywhere yet to see, but just thought you guys might have some ideas. I dont know if the clutch is going out or if it just needs adjustment or something else. It changes gears fine also. So if you know something please let me know. Thanks..
