John Deere 37a loader

[Texgasser1]

I have a 37a loader on my John Deere 3010.

It has been off for almost 7 months. Just mounted it back on and I don't seem to have any flow to it.

I honestly don't even know where to start, or what to look for.

We need to know how it is plumbed to the tractor such as from the remote couples using the SCVs to operate the loader, from the remote couplers to a dedicated control valve on the loader, direct into the tractor hydraulics with a separate control valve for the loader, etc.

If you have any quick connects in the lines it is important that they fully coupled and are matched to, the correct mating couplers. as the first step.

It is run into the rear couplers, There are no quick connects.

Please clarify your statement "no quick connects"? All JD 3010 with selective control valves had quick connects/couplers. Normal 3010 rear breakaway couplers have a lever that must be moved 90° to turn hyd oil flow on.

There are no quick connects anywhere other than the standard rear couplers.

Standard JD 3010 Rowcrop tractor rear hyd couplers were designed to be breakaway!!!!!!!!!! Please post photos of your 3010 rear hyd couplers!!!!!!!!!!

I think you must have male quick connect ends going into the SCV couplers.

Does it use the SCV(s) to control the loader movements? Or does the loader have its own valve?

The factory couplers on a 3010 are QUICK COUPLERS just not aftermarket couplers if the implement becomes unhooked they will breakaway, become uncoupled by the pull on the hoses as far as flow, check to see that the couplings are working correctly

Loader has it's own valve

I Unhooked a hose from the loader valve and left it connected to the coupler. Shouldn't there be oil pressure in the line? Because there is none.

I think you are going to have to do a better job of describing what it is that you are doing. This statement makes no sense, to me anyway. Post pictures of the plumbing.

This is the loader valve.

Do you have your scv lever pushed forward or backwards so oil will flow to the valve

The lever on the dash is pulled back and the levers on the coupler are both pushed down, That should permit the oil to flow.

If the dash lever is pulled all the way back it’s in ‘float’ and there wouldn’t be pressure on the lines.
