B2150hst 3pt Lift Height Adjustment

[NorCalOrange]

When raising the rotary cutter to 1/2~2/3 or more the hydraulics start to scream a little, make more noise, as if its straining. Their is ample room for the cutter to be raised more as the cutters drive-line is several inches form the top of the cutter. This happens even with pto disengaged, fel empty, rpms @ 2k and in low gear.

After reading many threads it seems that their may be an adjustable limit rod which activates a relief/control valve? Is the rod labeled #70 the way to do this? One thing though, their is only about a 1/4" of adjustment left on the rod threads to extend the rod making it longer.

Also, is the louder noise, I assume its a relief/control valve, bad and hard on the valve causing premature wear?

It's not a feedback adjustment issue! Do not randomly adjust the feedback or everything will quit working properly.
The reason it making the noise is that it's going into relief, (it's meet load limit), you could have a relief valve that needs adjusting.
You need to read the WSM to understand how to test and adjust the relief valve.
