You will be able to set the pressure relief properly if the pump is running at 10GPM or less flow. If you are not running the tractor at full RPM you will not be getting 14GPM flow. You should be able to set the pressure relief just fine at idle speed.
If you are running full RPM you will be exceeding the relief valve's capacity so the pressure will exceed the set point unless there is another relief valve in the system that is also working which may accomodate the excess flow.
You need to check the pumps rated RPM, which could potentially be 3600RPM. If the pupm is rated 14GPM@3600RPM (like a gas engine application) you would get around 7GPM at 1800RPM which would be about the top for a diesel tractor and direct drive to the pump. I don't know about you, but I don't typically run my diesel tractor above 1500 RPM.
