Log Splitter and Backhoe Question

[JK10MF1635]

I have a MF1635 with the MF CB20 backhoe and the power beyond to run it. I am looking at 3pt log spliters and am wondering if I got one that didn't have the reservoir and PTO pump, and just runs off the tractor hydraulics could I just hook it into where my backhoe plugs into? Obviously if I'm going to use the spliter the backhoe will be off. I do not have any rear remotes so that is why I am wondering if this option will work. I don't see why it wouldn't but am not sure. I would think that would supply the hydraulics and then it would be operated by the control valve on the spliter.

What do you guys think?

Thanks

I think that is what the power beyond port is for. At least that is what I have been reading.

Get the shop manual for your tractor and trace out the hydraulics (the operators manual won't have this info). On my Kubota the BH is one of the first connections in the system. When I disconnect the BH I have to connect the P and PB hoses together. The clue is whether the BH has three hoses or two. Unless it is the last unit on the PB system you have to maintain the PB circuit by using a log splitter valve that continues the PB (probably an option for the splitter). Takes then all three hoses. JJ is the TBN hydraulic expert and he clarified all this for me as well me as tracing out the circuit. He will probably weigh in soon.

Its been a while since I have looked at it to know exactly how it runs, but I do have 3 hoses. And when I take the BH off one of them gets hooked up to a return line so the fluid continues to circulate and the other two are just capped off, if I remember correctly. I have also read that some guys are disconnecting their FEL and using that as a hook up for the spliter. That is what got me thinking that I could use my power beyond. I will continue to look in the archives to see what I can find, and maybe give the MF dealer a call tomorrow.

Also I'm wondering what kind of power or tons of force I could expect with my tractor? Sounds like with my flow rate compared to some other post I have read that I may get full force out of a splitter. My specs are16.5 GPM total flow and 11.6 GPM at the remotes.

That's similar to my set up. Kubota L3130 with BH90 backhoe. I bought a northern tool log splitter and it connects and works straight out of the box. No adaptation or alterations needed.

"Tons of force" is directly tied to cylinder size. Larger cylinder diameter=higher force but with slower cycle speeds. The trick is in finding the balance between power and speed. I think most commercial 3-point units use a 4" cylinder and yield 15+/- tons.

If your flow is under 10gpm and you want to go 3pt, get a unit with a 3.5 inch cylinder. 4 inches will be too slow. Tonnage on logsplitters is way overrated. My 955 with a ramsplitter 3.5" probably is not getting any more than 12-13 tons and it splits everyting I throw at it. I would also get one that can split vertically as well as horizontally.

Does your 3PT hitch and FEL work when the splitter is connected? Does the splitter valve have the PB hose connection so you can hook up all three hoses same as the BH? On my BX 25 it is obvious in the diagrams that other hydraulic items will not get power unless the PB circuit is maintained.

You are correct in your thinking. You should have no problem using a log splitter on your tractor hyd.

If you have no attachments connected, there should be a jumper hose for the two QD's so there is a complete flow path to tank.

You would be putting the log splitter in series with the hyd flow.

If your tractor only has low GPM's. there is a log splitter valve by Prince the LSR-3060 that will take 4 GPM, and make it seem like 25 GPM, which will speed up the log splitter operation.

I just looked at your hyd flow, and it is about 11.6 GPM's. and that is good with the regular log splitter valve.

4 in cyl, 2 in rod, 11.6 GPM's

Extend time 6.75 sec

Retract time 5.06 sec

Total cycle time = 11.81sec

I say go for it.

Push force at 3000= 37,698lbs = 18.84 T

Pull force at 3000 = 28,274 lbs = 14.137 T

PUSH--------2500 = 31,416 lbs = 15.7 T

Pull----------------= 23,562 lbs = 11.78 T

You have three hoses at the rear. a pressure hose , call it AUX1, a hose from the 3pt , call it AUX2, and a tank hose from the BH.

If no attachment is connected, a short hose will connect AUX1 and AUX2 together to complete the flow path through the 3pt and to tank. This is normal flow with no attachments.

If using BH, AUX1 is connected to IN for the BH. AUX 2 from the 3pt is connected to the PB on the BH for the correct flow path. The AUX3 hose is for the BH cyl OUT fluid and goes to tank.

To use log splitter, Connect the AUX 1 to the IN on the log splitter, and connect the hose from the log splitter OUT to the AUX2, AUX3 hose is not normally used with the log splitter.

A potential problem exist using the OUT port on the log splitter valve for the flow path, as the manufacture has put about a 500 psi limit on the OUT port.

There is a way around this and that is to use the 3pt to position or set the log splitter working height, then lock the 3pt descend knob down to lock in place.

Now the OUT hose from the log splitter will go to tank with no possible back pressure, and AUX2 hose is not used. The 3pt is not in the circuit anymore. Log splitter will have normal operation.
