A friend has a 6605 which I would think would have a similar set up. Our has external lift cylinders that are controled by a valve and a position sensor. If yours is the same set up follow the lines to find the valve. Don't know how to tell if it's the sensor. It should be on the top next to the hydraulic valves.

Also his has a selector that limits how high the 3 point will raise. He once turned it all the way down, so the 3 point didn't raise at all. Took me a while to find what he had one.

It could be an electrical issue also with the rockshaft control.

You can also go under Deere.com and look up parts. Look for that model and Rockshaft. It has drawings that show the parts for the lift to give you an idea.

There is a screw on the rockshaft stepper motor for direct actuation. You have to unplug the electrical connector, remove a plactic cap and use a screwdriver. Turn right to raise. If this works you know the problem is electrical.

I had this issue on a 6405. It did work with the screwdriver. Turned out to be a poor connection with electrical connector. After I cleaned it up, it worked like a champ again.

First of all check the rockshaft fuse.
If ok check the steppermotor connector, like pclausen said.
If not working yet try with the screwdriver in the top of the steppermotor to check if hydraulics are ok (probably are, but check it anyway).

If it's not yet working I can guide you inside the Electronic Unit to see what's the problem, as long as your tractor has a cabin and a digital display in the instruments panel.
