Hi:
Just a recommendation. They are a little bit more $$$ but I got a splitfire
log splitter. (Probably around $1000-$1200) (My dealer charged me a little under $1500 for it and the PBY connection on my 3320. I also plan to use it on my 2305 (I have a PBY connection for a backhoe).

They split in both directions which will avoid you having to wait for the piston pull back cycle. I've used it on my 3320 and it's great, actually pretty hard for 1 person to keep up with it (not at full engine RPM either).
The Flow you'll have on the 2320 isn't a lot so with a single direction splitter you'll probably be spending a lot of time waiting for the piston to cycle back. This unit you just flip around the pieces and cut on the backstroke too.
Interestingly, when I was looking, I could have got a gas powered log splitter for less than the PTO mount one at Home Depot, etc. with a higher hydraulic flow, but none of them were dual direction and I really didn't want another engine to maintain.
One thing after using it I can tell you is absolutely phenominal (all 3pt units, not just the split-fire) that is a non-advertised feature is back strain relief. A standalone splitter you cannot adjust the height so you either have to bend over to use it (Try being bent over all day when your over 40) or reach for it. I'm not talking about lifting the logs, that's over quickly, I'm talking about holding the pieces before you split them, etc. all day long.
With a 3 pt one you can adjust the height so your back is just 'perfect'. - Maybe I'm just getting old.
