Which rating for hydraulic flow

[Stomper]

I have a Kubota L2501 HST and in the manual it says that the hydraulic system pressure is 2205psi and flow is 5gpm (main) and 3.3gpm (ps). What does "main" and "ps" mean. Which flow rate would would I have if I used the power beyond on my loader valve to install rear remotes.

The 3.3 GPM is power steering.

Thanks.
I kind of thought that maybe that's what it meant but didn't really know why that would be relative to anything.

Your welcome. Good luck with your remotes project!

Most of those pumps have 2 “pumps” inside them. One for the PS and one for the rest of the machine. You don’t get the extra flow from the PS side, or vise versa.
