Loader stuck in air Deere 4610

[turboviking]

Hello! I have a JD 4610 with factory installed rear hydraulics - and it is switched electronically with a rocker switch on the right operator's console panel. Some time back a problem started that after mowing or doing work with the rear hydraulics only, the front wouldn't re-engage. It wants to and when the switch is pressed the rear is disabled (top and tilt) but the front loader won't work. The tilt function works fine, but the raise and lower won't. I've checked wiring, and such, but now I'm stuck with the loader in the air and it won't come down. It WANTS to do something and will go up and down about an inch or two, but that is it.

Any idears? Anyone really understand this setup and what valves / solenoids etc. do what?

Thanks in advance.

I have not got the electronic set up but something similar happened on my 4520. Did you by chance recently remove the loader? I removed mine one time and got the hoses crossed and it did the same thing. Hope that helps. Mark.

Reseat the QD's.

VERY IMPORTANT!!!! Be sure to support the loader before you start working with QD's. It could fall on you and hurt you very badly.

Yes, with it in the air there will be pressure on the fluid in the lines. It may not fall because it should be captured automatically as the QD is released, but that pressure from supporting the weight will surely prevent re connection.

Are your loader valves solenoid operated or manual?

If they are solenoid operated, you could apply 12 v to the solenoid .

Some solenoid valves also have a manual way to move the plunger.

Hello, it is solenoid operated. I see only one solenoid. I plan to remove it and check the condition - but still seeking someone who understands and can explain the design of this hydraulic circuit. HUGS -

I assume the QDs are quick disconnects. I can do that and will. Thanks for this suggestion.

No, Mark, loader has not been off for some time. Thanks
