massey ferguson 1145

[mf1145]

I have a mf 1145 tractor, I'm having a little trouble with the three point hitch, It has the draft control on it also, my problem is the control lever beside the operators seat does very little to raise or lower the arms but i can go down under where the linkage is and get things to move, I do have the service manual but there is not a clear picture of how all the linkage is setup,A picture ,diagram or any help would be appreciated !!
Thanks LT
