1550 pto/3 point

When I have the pto out of gear (the handle all the way to the back) and I lift the 3 point all the way up, the arm comes in contact with the pto lever and pushes it forward enough to slightly engage the pto. I know if I don't lift it all the way it wont hit but that is difficult to do as the rpm are pretty high to make the 3 point work. Even if I stop it short of coming into contact it will ultimately work it way up enough to make the pto spin. I can put a stop on the lift control handle that might work but I'd really like to be able to lift the 3 point as high as possible which I understand maybe just before it touches but I'd guess that Oliver had it figured so that you could lift all the way and not hit the pto lever if everything was right. It's nice to be able to lift the Haybob up and over a windrow. Anyone have an easy solution?
 
Slightly engage the PTO, lift lever to top. Shut off tractor, go around the back and see if you can lift the 3 point arms. You should be able to lift them a few inches. If there is no travel left you need to adjust the control linkage. The lift piston can turn the rockshaft far enough to break open the back of the hydraulic unit.
 
If I read this correctly you may need to make 3 adjustments. The first is as Ian said. The second is you need to tighten the friction disk that controls the tension on the handle that controls the 3 point and you may also need to adjust the PTO linkage between the handle and the PTO clutch arm. You should also tell us if you have a single or dual speed PTO and if your control handle is on the right side. You have an Operators manual? This will all be covered in the manual. J.
 
Ok thanks. Lots to check. I do have a manual. Tractor has single speed pto. Pto engage lever is on the right side. Same side as 3 point control.
