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
