Then your system is not like my BX2200 system, unless the relief valve you mention is the PTO relief valve, or unless you main relief valve cannot even hold 68 psi.

Sounds almost like the priority flow valve has lost it's sense of priority. My tractor, the PTO requires almost zero flow and 68 psi. Yet, due to the design of the system, it is entitled to priority flow of 1.8 gpm, potentially at full system pressure, which never really develops because it is relieved by the PTO relief valve at 68psi as hydrostatic makeup flow.

Yes I believe it is different than the BX, I was told they were similar. It only has about 4L flow and the pto is not priority I think the deck lift is. I did shim the relief and it made a big difference but the pto will still cut out with deck lift when oil warms up and rpm is down. Just a weak system.
