Loader operations on RK tractors

[ovrszd]

When I purchased my John Deere 440 loader, they used the “Blended Loader Valve” as a selling point. There seems to be a noticeable in-between direction (at 45 degrees), that gives the dual function. It works smoothly at any RPM.

Yeah, I have two loaders, they do both functions at idle, just slower.

I believe it's in the valving rather than gpm.

Page 3-22 of the RK55H/HC owner's manual:
"IMPORTANT:
Do not hold the lever in the "Pull" or "Push" position once the remote cylinder has reached the end of the stroke. As this will cause oil to flow through the relief valve. Forcing oil through the relief valve for extended periods will overheat the oil.
When Using the tractor hydraulic system to power front loader,do not operate the boom and bucket cylinders simultaneously."
That said, same experience as other RK owners. In addition, my older NH behaves the same.
