So I got a new gauge and ran some more test. With the gauge hooked to the port on the regulating valve that would go to the PTO control valve. Line to PTO Plugged. Engine at 2200 RPM the readings were 167 PSI in low DP and 10 PSI in high DP. Then I unhooked the line to the DP from the regulating valve and capped the port and plugged the hose. Engine @ 2200 RPM reading was 167 PSI. When I pushed either brake pedal the pressure would drop to 157 PSI. Also the tractor would attempt to move with pedal in low DP even with line unhooked. I took the DP regulating valve spring and spool out and they both looked good. The plug that holds the spring in was pretty hard to get started back in. Is it possible for the lube circuit to cause the low pressure overall reading? Do I need to split it? Could it have a broken piston in the high clutch? Don't have a flow meter. Thanks! Cedric
