3-point won't go down

[Marty Lucas]

The 3-point on my 602 won't go down. (It goes down when it is parked.) When the engine was off I used to be able to wiggle the hydraulic levers back and forth and it would go down, but now nothing.

Is this an amateur fix? Or do I need an MM PHD?

(You probably have done this allready) but have you checked the rate lever under the seat? Straight ahead is normal drop-when it is turned to the left (when sitting on the seat) it slows the rate of drop. You probably knew that allready and have done it. You could take the cover (rate and cycle levers) off and see if anything looks like it is broke or bent. My 3pt on my M5 goes down slowly as I use it and have to constantly correct it so Im going to have to tear in to it sometime. Do your levers all sit straight across from each other? The valves may be out of sync. I cant think of anything else at the moment.

I have moved the levers around with no result, but haven't opened it up yet. The levers seem to be all across from each other.

I'll open her up and see if things look bent or broken.

Thanks

I forgot to mention, there is a roll pin on the end of the shaft by the lever. I dont believe they usually break, but that might be another place to check. Does the 3pt lever seem to "move" like it is working in all the positions when you move it?

The 3-point lever seems to move like it should. This weekend, I"ll open it up and take a look to see if anything is bent or broken.

I have a 670 that is doing the same thing and I have not tore into it yet but I need to. Mine goes up in all positions and it always has pressure on the hydraulic system. I am not sure what all it takes to rebuild this system but if anybody has any tips let me know. Thanks
