I spoke to the svc manager. The machine is in spec- all reliefs are correct, the oil was at about 160 degrees and theachine was at Max engine rpm when he started turning the valve to increase resistance through the flow meter. The reason that there is a "linear drop" is because he stopped at every 100psi to log the flow.
He has reinforced what I was saying in that none of the high flow machines he has ever put a flow meter to will put out the high flow gpm shown on the brochure at te max pressure listed on that same brochure. I've known this guy since I was selling Bobcat machines in my past life and he doesn't have a dog in this hunt so the numbers are what they are.
