Help with power beyond and log splitter

mlip · Apr 17, 2007

Folks,

I'm looking for some guidance on hooking up a 3PH log splitter to my JD4300. The previous owner had a back hoe and I believe had the power beyond kit installed. I've attached a photo of the back end of the tractor.

My log splitter mounts to the 3 point hitch and has two hydo lines, one supply, one return. Where should I hook the log splitter lines to? I've labeled the tractor hydraulics as A, B and C.

Thanks.

Mark

Hi--I believe that you should connect to A & B as C is used when the BH is on (disables the 3PH). If you connect to A & B then you can use the 3PH to raise the splitter to a comfortable working height.

Right On

B8FISH is absolutely correct, happy splitting

They are correct, but you should make sure you connect the hoses correctly. In other words.. make sure the flow is going the correct direction from the tractor to the splitter and then back to the tractor. You will need to have hydraulic hoses made. You can get the correct ends for the hoses from your JD dealer and then have them attached to hoses from someone who makes hydraulic hoses... you also need to make sure you know what size the fittings are for attaching the other end of each hose to your splitter.

Having the same setup on my 3120, I'm curious about the direction of flow and how you detemine which direction other than trial and error. Would it be out A and in B, or are there markings at the fittings that I haven't seen?

Hankus....I'd like to know that too. Anyway, thanks for the info, my splitter has 3/8" hydo lines installed, I just need the quick disconnect couplers, I'll be making a visit to a local shop to get those. Once I figure out which is supply and which is return, I'll be set to split. Its a good thing, this winter just doesnt want to give up here in New England. I'm down to my last weeks worth of wood, went through nearly 5 cord this winter!

OK guys, this is simple...
The fluid flows OUT of "B", the fixed hose. And can flow IN to either port "A" or "C". But as B8FISH already said, Plugging into the "C" port will disable the 3PH, while the "A" port will not.

As for the 3/8 hose, you just want to make sure that the hose is at least the same size as the "loop" you are connecting to. You do not want to restrict the flow of oil through the splitter or overheating can occur.

Kennyd....thanks, sounds easy enough. I will verify the hose diameters for possible restriction issues......BTW, I only got to use my plow set up once this winter. It worked great, but we didnt get much snow....at least when I was home......Mark

Good to hear you got the plow operational Mark, and you'll have the splitter working in no time.

B8FISH · Apr 17, 2007

KennyD--are you sure that it doesn't flow out of A?? At my dealer I saw a 3520 set-up with the BH on and the "hose" was not connected to anything. Dealer said that you needed to connect the hose (B) to get the BH off and on and use connection C to operate. Looked at JD Parts and it seems to confirm my suspicipion as well. A seems to be the "main" supply.

B8FISH,MLIP, and Hankus:

I stand corrected, I jumped the gun on this one... The main supply line is "A", with "B" going to the 3PH, and "C" going directly to the tank, bypassing the 3PH.
So "A" should go the the "IN" of the LS valve, then the "OUT" of the LS valve goes to the hose "B".
Also remember to match the hose and QD size to what you have on the machine now, this hose has the hydraulic flow of the whole machine going through it, you do not want to restrict it.

I sincerely apologize for any inconvenience I have caused...

at myself!

Long time back i was given a huge splitter with a 4" piston desighned to mount on a 60hp Massey. I swapped the 4" for a 21/2" from Princess Auto and leave the whole unit chained to the woodshed(upright). I made sure I got long enough hoses so I only have to get "close" to hook it up to A&B. (Actually I have a couple of 5" extension hoses with QDs on each end) The 21/2" is way faster than the leaky 4" and still has ample power at 1500rpm

Interesting... I've got an A and a B port on my PB circuit. I was wondering how that C port worked.

Great place to always learn somethin' new!

I picked a big honkin' 3pt log splitter a couple years back and have never used it, either. Probably a 3" ram with a 24" stroke at least.

Thought about sellin' it but have no idea what one is worth.

Thanks for the guidance, got it hooked up and running today. Works great, now We went through almost 5 cords this winter, now its time to stock up for next year. I just need to keep those boys working on the woodpile and keep their fingers away from the nasty bits of the splitter! I really like this set up since I can lower the 3ph to roll big logs on that are too heavy to lift.

AKfish · Apr 20, 2007

Nice lookin' splitter. A couple of fine lookin' lads there as well! Do you suppose they'd mind commuting for a little extra work?

funny you should ask......I got about 45 minutes of free splitting out of them due to the novelty of the new toy. After that they started asking for cash...I siad no, they left to play lacrosse. I suspect I'll be negotiating labor rates soon...
