Slow 2290 hydraulics

I discussed this several months ago. Now I am ready to fix it. Whether on the field cultivator or 8 row planter the hydraulics operate slow. It always lifts, just slow. I tried new female and male couplers. No difference. I have checked the flow valves and they are on the fastest setting. I have NOT DONE THE FILTER. NOW HERE IS SOMETHING INTERESTING. On my planter one valve served the lift wheels and one valve served the markers. When lifting the planter individually or the markers individually it would be slow. WHEN I MOVED BOTH LEVERS AT THE SAME TIME it seemed to lift NORMALLY OR AT LEAST 5 to 10 times better. Someone told me that there is a valve that senses hydraulic use on the two valves and maybe the 3 pt. The valve has little hydraulic lines going to it and a little line that goes to the pump which varies a plate in the pump to increase or decrease the flow.

Do you guys think that this sensing valve might be my problem?

Someone told me it hardly gives any trouble but could.

What goes wrong inside of it to cause this?

Is there anything else I am missing that I should look into? Thank you. andy
 
Remove the remote valve signal line (the small line on the remote valve) remove the fitting, behind it is a small spring and ball, check it out. Like you said having trouble with it is rare but possible. It sounds like the hyd. pump is not going to high pressure standby all the time. I would try adjusting the compensator.
 
I looked at the remote valve assembly today. It was still on the tractor. I can see one valve and next to it another valve. On each valve there are two pipes attached. One above the other, each pipe going to the rear of the tractor for the outlets. Also on top of the valve assembly are the flow knobs and the assemblies to push or pull each valve. Now, having you know what I know about the valve assembly, can you tell me where these lines (thin lines) are, and where they go to this control valve that varies the pump flow?? So, where is this line with the ball that should be checked? And where is the unit that this line goes to vary the flow? Somewhere there is a valve unit (can't remember the name) that manages all of the remotes and pump flow. Anything you can describe helps. Thanks. Andy
 
i'm sure you turned the flow control on top next have you chk.press. at back just plug a 3000#guage in each port an pull lever each should be around 2000#(ck. all) the most common problem i see is on the back of each valve is a plug with a screwdriver slot remove an you should see a small o-ring usualy gone or broke
 
When you say "one the back of each valve", do you mean the bottom of the valve or actually on the backside of the valve body against the transmission? Thanks. andy
 
agains't the tractor the valve has to come off just take your time there is copper spacers and o-rings between each take your lines loose first. did you ck. press? on the same valve usualy one will be ok the other weak
