606 Diesel hyd problem on tractor I have had two years

My 606 hyd had been working fine to my limited knowledge. I use a heavy blade to grade about
1 1/2 mile of dirt gravel road. My controls are two levers with an up and down position on one and a draft light or heavy on the other. I ran it on a fire break around my property for about three hours, raised the blade, parked the tractor, lowered the blade and it wouldn't raise again. I changed the hyd filter and added fluid to full. Still wouldn't raise. The power steering works fine. Removed draft hyd cover and saw bubble coming from large cylinder. Removed cylinder and control valve assy and found that the hyd safety switch had been removed by someone previously. I rebuilt the cylinder and installed a used safety switch. My tractor has two levers for aux hyd that I had never hooked anything up to. I found that the top link where it hooks up to the draft control is rusted and dosen't move to operate the safety switch. The draft control would still not raise the attached blade. By accident I found if I moved either of the two aux hyd control levers that the blade would raise or lower with the draft control lever. I am still trying to free up the rusted top link draft control. Does anyone have any suggestions for me
