I am looking to run a drive motor on the FEL of my 2020 L2501 using a 3rd function valve kit from my power beyond port. The motor is specd for 7-18 GPM up to 3000 PSI. The hydraulic flow rate of my tractor as I understand it is 5.15 GPM. Is there any way to upgrade the pump to get a little extra flow here? If I use shims to bump up the pressure, would that also bump the flow a little? The other option would be a PTO pack but trying to avoid that if possible. Thanks in advance for the help!
