Adding additional hydraulic circuit to JD 410 backhoe

[acadie1]

Good day,
I would like to add an additional circuit to the rear of this machine. I would like to be able to run things like a grapple, post hole auger or even wood splitter off the end of the boom. This would make the machine much more useful on a-day-to-day basis. One suggestion from a local heavy equipment tech would involve tapping into one of the stabilizer circuits. This machine has a closed centre constant pressure system with an accumulator. I was wondering if any one has attempted any thing similar and would appreciate any info on how they went about it.
Thanks in advance.

Remove plug(item 20) from pressure control valve on RH side of trans case. install fitting to attach hose then route hose to "in port" on control valve. Route "out port" hose on control valve to ported hyd filter cover(item 10 2nd photo). Be sure any added control valves are set up for closed-center hyd's
