JD 4320 - hydraulic question

Hello all,

I purchased a 4320 a few months back with a 400 loader. I love the tractor but I didn't add any rear hydraulic hookups. I'm wanting to purchase a log splitter that runs off the tractors hydraulics. Can anyone tell me what hydraulic kit would be best to operate a log splitter? I called the dealer and they said $1500 for rear hookups with an SCV lever. I do not know much about this but I do not believe I would need that. I read somewhere about a power beyond kit. Would this be what I needed?

Thanks
