Quick Attach Lever (Smaller Hoses )Pressure and Flow Rates

[PowerTracManiac]

When I flip the PTO switch on my PT1460 the specs on the PTO (large hydraulic hoses is 3K psi and 18 gallons per minute flow rate).
What if I want to use the quick attach (small hoses) for something? What is the PSI and flow rate on those smaller hoses?
I use the small hoses for my grapple (open/close the grapple top arm) and the quick attach cylinder clamp. I have never needed the small hoses for anything but the grapple and the quick attach.
I am considering getting a hydraulic telescoping extendable boom crane and want to use the quick attach lever arm control (small hoses) to open/close the hydraulic rams inside the telescopic boom crane.
Wondering if anyone knows the pressure and flow rate for the small hoses?

Guessing 7 GPM. Most people don't want to have the crane move quickly, it should work well.

I have no idea about the specs but the power attach on my skid steer moves slow and it’s not very strong. It has difficulty latching if there’s any dirt in the way. I’d be surprised if it’s over 3 gpm and 500 psi.
