Just wondering on the hydraulics on this JD 1560 drill and my White 2-135 tractor. The tractor has closed center hyds. The drill needs down pressure. It comes as a closed center system, but has an optional valve that can change from open center to closed center.
If I understand right, I need to have it on closed center and then lock my remote lever forward (down)to keep the oil flowing through the drill hyd system and keep down pressure on the openers, etc.
My problem is that it seems like when I hold the remote lever in the tractor forward, the hyd system seems to be growling, like I need to release the lever. I may be dreaming, but it sure seems like it. I don't want to burn the pump up or anything. Any suggestions? Also, the hyd pressure gauge has been changed out from the original gauge that has green, yellow, and red pressure zones, to one with psi. Any idea where the psi might be in normal conditions? Just an approximate to have something to go by. The JD750 drill I traded in had an entirely different set up. Thanks for any help. Bob
