Backhoe 3Pt log splitter off backhoe lines

[radioman]

RobA,

My HF Splitter has not arrived yet so I have to live through you for now!

Post Pictures when you can!

Radioman,

I am a bit worried now from what you are saying. All I was going to do is hook up the Splitter to my B2920 inlet and outlet BH ports. From what I think I am reading here the usage of my 3 PT lift maybe questionable....I was hoping to drop the splitter on the ground to pick up the larger pieces .

Sorry- didnt mean to make you worry. I have been trying to understand my own BH system . I think I was a bit wrong int he statment of losing the 3 pt lift. I think as long the pump side of your B goes in the splitter A or inlet and then the splitter out to the power beyond return on tractor. With a OC valve on HF splitter, you should be able to use the 3 pt with no issues. IF you connect the out let to the other return port, you will lose the FEL/3 pt use.

I got the splitter out of the wooden crate is was packed in (the thing is a beast!) and mounted it on the 3PH. Picked up a 5' and 4' hose at Tractor Supply. Probably could have gotten by with a 4' and 3' hose. Their hydraulic fitting selection was limited so I went to the Kubota dealer for the quick disconnect fittings. After attaching them to the hoses I realized they were not the right QD fittings. Drove all the way back to the Kubota dealer to get the right ones but they didn't have any. Too late on a Saturday to go anywhere else so it will have to wait. Hopefully I'll be able to find the right ones.

The QD fitting I bought was slightly different than what is on my tractor. The fitting on the bottom in the picture is the one I bought today. The one on top is from my tractor.

The QD fitting I bought was slightly different than what is on my tractor.

The upper one is an "ISO 7241 series B".

The lower one is an "ISO 5675".

There is also an ""ISO 7241 series A", too. My Kioti and Bobcat uses them.
My JD uses series B. I have seen the 5675s, but never had them on any
of my tractors. Is Kubota using them now? My older Kubs used some
metric size, I don't remember. All three of these standard QDs are made
by all the major makers, as far as I know (Parker, Eaton, Pioneer, etc.). I
would NOT buy any of them at your tractor dealer. It turns out, they did
not even know the right type for your tractor, and they are prob 2x or 3x
as much as at DiscountHydHose.com.

Thank you! The first time I went to the Kubota dealer I didn't have the QD fitting with me. When I went back I took the male fitting off of the tractor to show him. He seemed a little puzzled. Strange since that is where I bought the tractor. They only had the male in stock and said there was no spot on the shelf for the female fitting. They have always been helpful in the past but not so much this time. I'll check out the JD dealer tomorrow morning. If he doesn't have it I'll order it online.

Thanks again for helping a novice out.

They only had the male in stock and said there was no spot on the shelf for the female fitting.

That makes a crazy kind of sense. A new tractor with a factory AUX valve
setup will usually have a bulkhead with 2 female QDs for each circuit. That
means the user needs 2 male QDs (aka plugs) to connect to his implements.
Hence, the dealer usually gets requests for the males.

When I have a tractor with that kind of AUX setup, I switch the bulkhead
over to one female and one male QD, and the same for each implement.
This keeps me from hooking implements up backwards and I can connect
the loose implement hoses together when it is not mounted. That keeps
them clean.

Happy to help.

Took the day off today and finally got the HF log splitter hooked up. Went to the JD dealer to find the right QD coupler. They don't carry it. Went to the New Holland dealer - same. So I 'borrowed' the fittings from my backhoe. I'll order new ones online and put them on the backhoe.

The splitter was easy to assemble and hook up. The only problem I had was that I didn't tighten one of the connections enough and had to clean up some hydraulic fluid off the barn floor. It works fine. I had no problems spliting the logs I had. It's not the fastest but I like that - keeps me from rushing and hurting myself.

Oh, on the Kubota L5030 with backhoe hydraulic connections you do not lose use of the 3PH when the splitter is attached. I can lower the splitter to load a larger log onto to the cradle.

I am very happy with the splitter. The low cost made it even better.

Thanks to everyone here for your help and ideas.

RobA,

Thanks for the picture - boy I am jealous as I still have not received my HF Splitter yet (they are on backorder) but for $399 I'll be happy to wait!

You stated that it was a bit slow - I was wondering about the entire cycle time - do you clock it? I read someone stated about 22 seconds which I think it pretty good - if I was looking for speed I would have went with a stand alone for much more money.

I decided to wait and get the splitter before I buy any lines (to determine the best length) and bolts.

Have fun and good luck!

I didn't clock it but it was no where near 22 seconds. Keep in mind the logs I was splitting were nearly the same length and split easily so I never had to to fully extend or retract the piston. Maybe it's not as slow as I thought .

1 more thing - others on TBN suggested that the 4 bolts that connect the top link support be replaced with hardened bolts. Good idea but keep in mind they attach to a threaded hole on the unit and there is limited space beyond the threaded hole. The splitter comes with M12-30 bolts. I replaced them with M12-35 bolts which wound up being too long in 2 of the 4 holes and I had to shim them with extra washers. No need to replace the bolts with longer than the M12-30.

I have a Tractor Supply splitter that runs off of the disconnects for my B7800 loader. I believe it has a 9.5 gpm pump. It runs fine and splits anything I put on it. I think running it off of the backhoe lines would work even better than my set up, but having no hoe on my tractor, it's what I had to do. Either way, I think you'll be happy with it.

I'm planning on using my backhoe connections on my L3400 in a similar way as the log splitter, except that I want too be able to change the angle on my rear-mount grader blade for snow plowing. Can someone confirm for me that the female connector on the tractor goes to the pressure in on the remote control and the male on the tractor is the return line ? Thanks.

On my L5030 the female is the supply and the male is the return. I confirmed this in my owner's manual when I was hooking up the splitter.

 

[grum]

Great - that confirms what I was told by someone else. Thanks for the help!

As usual, I've left this project way too long, as we have another big dump of snow on the way, but if I get going on it I'll at least have it for the last ( i.e. read worst ! ) half of the winter.

 

[jambx]

Maybe I am missing something and I have spread this question a couple of times tonight in a few other areas of the site - basically I am getting hoses made for my HF Splitter tomorrow however i am not sure which of my BH lines is the supply and which one is the return.

Can anyone guide me on what is the best way to determine this?

 

[Ductape]

Follow them back........ doesn't one come out of the PB at your loader valve? The return would head toward the three point hitch or sump.

 

[jambx]

They both terminate under the seat.

In the owners manual the male connector is the "Inlet" and the female the "Outlet" - which one of these would be the supply?

Would it be as simple as plumbing the inlet hose to the inlet valve of the splitter and outlet to outlet?...

Sorry but it just doesnt seem to be straight forward to me.

 

[Ductape]

I would assume so......... but you should be able to have your hoses made with your best guess (i'd guess the male on the tractor will feed the splitter, female on the tractor would be return). If you hook up the hoses when you get home and they are backward, its a simple matter of removing the fittings and swapping the ends to correct them.

Welcome to TBN Keith

You are correct in that the lines MUST be either connected together, or connected to a Open Center valve so that the fluid will have some place to go. There is the full flow of the hydraulic pump in those line whenever the tractor is running-and interrupting that flow can cause damage to the machine.

So basically, when the backhoe is removed-the two lines are coupled together forming the PB loop. You can insert a OC valve into the loop to power other things just the the backhoe is inserted into the loop.

Clear as mud?

kennyd, thanks for the reply. I've learned a lot from everyone on this forum.

Finally getting around to buying a 3 pt splitter. The hydraulics make a lot more sense to me now. If you run the return to the inlet that feeds the return to the 3 ph, you need to have a valve on the splitter that has an outlet side that can handle full hydraulic pressure (which will occur anytime that you operate any downstream valve, like the 3 ph, or FEL).

The alternative is to hookup the return to the tank instead of to the 3 ph (PB). The splitter will work fine, but your 3ph and FEL will not operate.

The best option is too have a power beyond type valve on your splitter (kind of expensive, though). This way when the splitter valve is in neutral position the flow will pass through it to the PB inlet on the tractor feeding the 3 ph and downstream valves.

A cheaper alternative might be to split the outlet from the pump. Feed the splitter with one leg and the PB with the other. Hookup the outlet from the splitter to the return to tank. Has anyone tried this??

I am no expert, but I haven't seen a post yet explaining it this way. So many posts that I've seen ignore that if you hookup your splitter via the PB circuit, you will expose the splitter valve outlet side to full pressure anytime that a downstream valve is operated. If I've got it wrong, please speak up. Thanks!

Keith,

While everything you wrote is technically correct-I does not need to be that complicated for a logspliiter. If it's plumbed into the PB loop, then it only becomes the "downstream" valve when the 3PH is used...and max pressure will not be seen from just moving the splitter up or down on the 3PH. There are MANY backhoes and lodsplitters plumbed in this way and you cannont find one post about a cracked valve.

A cheaper alternative might be to split the outlet from the pump. Feed the splitter with one leg and the PB with the other. Hookup the outlet from the splitter to the return to tank. Has anyone tried this??

So how would you "split" the outlet from the pump?
