Hey guys need some help. My 1983 John Deere is sick! On the two hydraulic values the inside one is suppose to push all the way forward to float! But mine will not! What should I look for, or just pull the valve out and rebuild? Only 1000 hours on the tractor.

The linkage may be gummed or rusted. Sounds like it needs to be pulled apart and cleaned up.

As said, you need to check the linkage and if it is tight and free then the problem could be the valve detent is stiff. As a last resort you may have to pull the valve apart but try these other things first.

Okay, time to tear into it then. Remove the belly screen and get in there. Make sure you have a clean area so you can find any parts that drop out of there. I bet the detent ball is gunked.
