L3800 + backhoe + logsplitter?

[zmjc]

I have a new L3800HST, which comes with a dealer-installed backhoe, and a FEL, but no rear remotes. The backhoe is connected through two hoses (tractor outlet, return).

I'm considering using a 3PH log splitter (maybe Wallenstein or Split-Fire), but I need to understand my options.

When the BH is off, the outlet hose is connected to the return hose, for a continuous flow. The outlet hose goes to the power-beyond of the FEL valve, and the return hose goes to the front hydraulic block, going through to the rear position control valve, I believe.

Can I use the logsplitter on the backhoe loop, while keeping the 3PH hydraulics alive (to support the splitter)?

The dealer said no, I need a rear remote valve, but I don't quite understand that. Then he suggested disconnecting one of the FEL quick-connect circuits and using it. But... why would I need another valve? The logsplitter has its own open center valve... right?

I've read through the various threads here on the same subject, and I'm inclined to think that the splitter could go on the BH loop (with the BH off). Is that right? Am I missing something?

I guess you never use the BH and the 3PH valves together. Is that why the dealer doesn't want you using the logsplitter and 3PH together?

I went through the same thing...with initialy same advice from a dealer. Others have used a log splitter exactly how you propose. The most help I got was on this site and it was from kennyd...he provided super help as I added my own open center control valve, hydro lines, fittings, etc. to a stump grinder. You may want to post this in the hydraulics section for a more reliable answer(s) on your particular model of tractor, but here is what I remember. When you remove your BH if you have to reconnect the lines back together to continue using the tractor w/o the BH, that means the circuit is a power beyond which is what you need for the log splitter (I was hooking grinder to a B2920). Anyway you should be able to use your 3pt as that is how the log splitter will mount. My 3pt. worked fine with this set-up. You can trace your lines from BH and they probably come out from under the seat and just so you have right inlet outlet lines hooked up correctly. I bought a Kubota Male and Female quick coupler that I leave on the implement for a quick hook-up.

I forget why you cannot use (and block control lever) on 3pt when BH is on. It may be that the BH is closed center...I'm sure you will get a more knowledgeable response from others.

Technically, you would need a power beyond port on the splitter since when the bachhoe is off, the hose loop is powering the 3 point hitch. What you could do however, is leave the loop connected until you get your splitter to where you want, drop it so that the 3 point lift is not supporting it and then take the loop hose off and connect the splitter. You would have to remember to disconnect the splitter and reconnect the loop when you need to raise the 3 point otherwise you could put too much back pressure on the splitter valve and blow out seals. If you do get a splitter with a power beyond, then you would need to find another spot on the tractor to connect a tank line from the splitter.

Hmm, interesting. Does anyone sell a logsplitter with a power-beyond port?

Just hook it to the backhoe hoses. You won't be operating the splitter cylinder and your three point hitch simultaneously..... so there shouldn't be any big issue.

I would call some log splitter manufacturers directly to see if they offer a PB option.

The problem is the tank port on typical splitter control valves are only rated 100 to 300 psi. Just lifting and transporting the splitter will probably take more than that.

You could use a double selector valve to isolate the splitter from the PB loop while lifting and transporting. Then when you are setup with the weight of the splitter supported on something other than the three point you could switch the selector valve to power the splitter. That way you would not have the hassle and mess of disconnecting and connecting hoses each time you move the splitter.

Yes, I agree. It's done all the time. There are a select few on TBN that will talk about how the valve will blow up from backpressure but no one can show where it has ever happened.

How many 3PH logsplitters you think are sold every year by various companies? And plugging into the PB loop is how most are hooked up and we NEVER see threads in the Hydraulics forum about cracked or damaged valves.

ZMJC-Get your splitter and enjoy it.

Not arguing on the merits (you are correct)...... just that the reality is, i've seen many, many connected to the backhoe loop. I've never seen a failure of a splitter control valve because it didn't have a PBY. Eventually I will have a three point splitter also (along with my stand alone), and this is how mine will be connected. Unfortunately, I don't live in a perfect world. Using up a bunch of extra time and money to protect a hundred dollar splitter valve when it has a minimal likelyhood of failing just wouldn't be my priority.

Good point.

I'll email Split-Fire and see what they say about the back-pressure issue...

They likely won't have a clue what you are talking about.:laughing:

If you hook your splitter up to the FEL bucket and run the hoses to the BH ports it is a easy swap of hoses and you dont need to remove the BH.

I have the Ramsplitter unit with legs and the 3PT setup where I connect the top 3Pt pin to the center hook on the busket and 15' of Hyd hose to the rear BH connection. Pin up the BH and disconnect the hoses and connect the splitter hoses and you are splitting.

Actually... Split-Fire replied to my email about the 3PH back-pressure, and said "the splitter can withstand the pressure. [...snip...] I had to consult one of the engineers here about that question to make sure."

Nifty!

Hey I don't have any answers for you, I just want help from you! I have a backhoe that I built a subframe for, and it's mounted to my Kubota L3800 Gear drive. It's hooked to my 3rd function remotes and my electric solenoid valve (a D03 valve) is getting HOT. It's the remote kit on Ebay from immigrantpines. It works great for round baler gate and anything else that only needs ran for 1 minute at a time....
So I'd like to hook the hoe up a different way....without an electric valve that gets hot. I want to hook those lines up like yours is, and when hoe is off, just make a loop. Problem is-----I don't know enough to do what yours already is. can you help direct me to hook mine up like yours? I have Ansung 2540 FEL, and the hydraulic block by your right foot is pretty similar to Kubota FEL I think. ANY help would be appreciated!
If I hook it up that way (like yours is) will I have full power from the hydraulics? I don't care if knocks out FEL when hooked up, I want my hoe to dig with all its might. It's a 1978 LONG 1199B and is mounted up safely and securely (4 point attach). Just wonder if the ole' hose loop hook up "misses" any available power?

We have a 3 point splitter from Northern Tool ("Powerhorse") which I hook up to the Power Beyond backhoe port on an MX5100. No problem, 3 point hitch works fine for setting the height of the splitter. I have never tried to operate the splitter and 3 point at same time (it would actually take 2 people to reach both). My tractor does have rear remotes, but to run a splitter off a rear remote you have to bungee the valve open to get continuous flow.
