Running a log spitter off of my power beyond hydraulics for a BX25

[bx25d]

So I'm looking at buying a Wallenstein WX310 3ph log splitter for my Kubota BX25. I want to run the splitter off of the power beyond hoses that are used for the backhoe. I don't know a lot about hydraulics but my concern is the splitters specs recommend a minimum of 10 GPM of flow to the splitter. The specs on my bx25 say that I have 6.2 GPM of flow. Will the splitter work with that flow? Also, what's the PSI's rated at for the bx25? My guess is that it will work and I will still have enough power to get through big logs but the speed with drastically drop. Would I be correct in assuming that? Any help would be great!

You are right.... GPM flow rate determines speed. Your full stroke cycle time will be close to 1/2 a min... but you should have plenty of power, Just will take longer.

It will be slower then that because the BX has a priority valve that takes a portion of the flow for the power steering circuit. This is why at near idle you have no hydraulic flow for the loader.

1850 psi at WOT for "kubota recommended pressure". I am not sure if you can get thru the big stuff though. You will have to ask al yelvington. He the one who documented the 3 pt splitter to work with his BX .

If using 6 GPM for the flow, here is the data for the cyl power and speed.

I guess one way to get around the problem is to just have a pto pump with hydro tank but that kinda defeats the purpose of what I'm trying to accomplish- especially when i have a 23hp diesel at my disposal and i cant even utilize it for a simple log splitter! Is there no other way other than a pto pump?!

Thanks for that data J J

You have about 1.8GPM going to the priority valve for steering, PTO clutch and Hydro charge.

So you will have around 4 GPM left for splitter. I have a Speeco 34 ton stand alone splitter with a 15 second cycle time or you may use a PTO pump for quicker cycle time.

When I am splitting large blocks I use the BX to move them.

I ran one on my BX22 it had about a 15 second cycle, which was fine for me. Worked well and I much rather have one less motor to maintain

Time for the 99.oo Harbor freight 6.5 horizontal gas engine. Then the pump,valve, and tank. You quickly see why splitting wood gets expensive.

Have you looked at the splitfire log splitters? I have a 3203 3 point model and love it. With splitting both ways it makes up for the lower gpm. The wallenstein looks like a good splitter too except for only splitting one direction.
