The manual for my tractor says not to operate the 3ph position lever when the rate-of-drop valve is all the way closed, because it will put the system into relief and can overheat the hydraulic oil. Seems pretty straightforward. But in another thread on TBN, someone said that, on their tractor at least, the valve only applies when the 3ph is lowered, and raising the 3ph with the valve closed didn't matter.
I don't know much about plumbing on these tractors. Can anybody speak to this discrepancy? Is this just something that is different on different tractors, or am I misunderstanding something?
