John Deere 5400 - 3 Point Hitch will NOT Drop

[dnkjr]

Inherited this tractor from my Dad who bought it new (1995). It has only 85 run hours and is used to shred or disc 3 acres a few times a year. When I hooked up to the shredder, it lifted a usual. When I got to the field, it would not lower. I called a dealer, who said that the rockshaft valve may need cleaning. I have removed the seat, rockshaft/draft handles and shroud. I also jacked up the shredder on 3 sides to take some weight off the 3-point hitch.
Questions:
1. Are the parts to be serviced/cleaned contained in the approx. 2" x 2" casting that has the rockshaft and draft control levers on the outside end?

2. How to get to the rockshaft valve? I assume it is inside the rockshaft housing.

3. Will there be hydraulic pressure on that part? If so, how or where is the safest best way and place to release the hydraulic pressure?

4. How much oil will I have to catch?

5. How and with what should the valves be cleaned?

All help and info appreciated.

Be sure the rate of drop screw(parts key #8) under the seat isn't completely closed.

9 times out of 10 that is the fix when people come on here with a 3 point that wont drop.

Jim - Thanks for the lead. That's the knob under the seat? I don't think we ever moved the setting, but will double check. dnkjr

Yep those things get bumped with your feet and then vibration will also close them. Happens about once a year or so for me.

Also, if you have kids, that knob gets moved. Although, if you ask, they never came close to the tractor.
