Check, clean or replace filters.

Check hyd level.

Is hyd pump turning?

Do you have a hyd gage?

 

[Bingoose]

The pump Is turning, the fluid Level ok, no gauge. CAN it stop working from a stop to a strat?

 

[J_J]

If the pump lost prime it would not pump fluid.

If the pump is good and you activate a valve lever, something should happen, because the fluid is flowing through all the valves.

A hyd gage would tell you if pressure is being developed.

Loosen or remove a pressure hose and place in a bucket to check flow.

Make sure the lever is not spinning on it's shaft going into the trans.

I can presse on one of the coupler not used and there is no oil or just à drop coming out.

 

[Leejohn]

That well not tell you much unless you can hold the coupler open then move the lever for that rear remote. One way you well get none and the other way you should get oil coming out.

If no fluid is coming from an open ended hose, then you are not pumping.

You said the pump is turning, but how do you know this. If the shaft as Leejohn mentioned is sheared off, the pump will not be turning.

Have you messed with any hoses/QD's and perhaps deadheaded the pump?

Hydraulics:
Valves: 2 to 3
Pump flow: 12.4 gpm [46.9 lpm]

Tanks, no, i juste stope the tractor and she was not working after.

Run a hose directly from the pump OUT port into a 5 gal bucket and check for flow.

If no flow, then either the shaft is sheared off or you have lost prime.

Check for in tank filter. If it is clogged, you will have no flow.
