Hyds for log splitter

I should probably post this over on TT, but I thought I"d try here
first. I have a log splitter with the motor blown and want to convert
it to run off my tractor hyds. My 8ns don"t have any so I have a
TC-45 with loader valves and a Ford 5600 w/ two remote valves.
Would either one of those be set up open center, or will some sort
of conversion be required in order to operate the splitter valve? I"ve
done a little reading but don"t understand enough to make
complete sense of it. If it is too much trouble I will just buy a
replacement motor for the splitter, but would prefer to work off my
tractors hyds if I can.

Don't know squat about the 5600 but it appears the hydraulic flow is roughly 12 GPM @ 2100 RPM. That will run most log splitters "OK". The flow on the TC-45 is a bit lower - roughly 9 GPM which, depending on the splitter, may or may not be "OK".

Your log splitter has an open center control valve on it - all you need is a CONSTANT flow from the tractor to that valve and back again. Unless you have some sort of constant flow remote on one of the tractors you would need to find a way to lock/tie one of the tractor valves in the OPEN position and use that outlet to supply the splitter.

Pretty simple arrangement and a bungee cord would probably get it done. Cheap hookup and easy to test. If it doesn't meet your needs then go buy a new motor.

Both tractors are open center hydraulics. On the 5610 you could just plug into the remote valve and use a bungee cord on the handle as TOH said. You just need to make sure you have the oil flowing in the right direction. On the TC45 you could either add a remote valve or you could tap into the power beyond hose from the loader valve.

That sounds fairly simple, but what about the return fluid? Will the
return fluid flow back into the paired valve or would I need to add
another return port to get the fluid back to the reservoir? On the
5600 there are two sets, each set is controlled by one lever. I
assume by supplying positive pressure through one, it opens the
other for return? Is that what is meant by open center?? I've only
used a brush hog which is pressured and returned through the
same line. Sorry if I sound ignorant about this.
 
Thanks, I meant the remote part for the 8n. Which for this job the 8n would probably be a better fit than running a 60hp diesel for a log splitter.
 
you CAN fab up a remote valve to the 8n.. just takes a lil plumbing ingenuity..

it's low volume so i'm not suggesting you do it.. just saying it is for SURE possible and people have run slowwww log splitters off N 2.9gpm/1500-1700 psi hyds before.

From your description your 5600 has a valve with two double acting spools (4 outlets) and it really doesn't matter whether the tractor system is open or closed center. When you move a control lever out of neutral pressureized fluid is sent to one of the outlets and the second outlet is connected to the reservoir for any return flow. That is all you need worry about.

To hook up your splitter FIRST connect the splitter valve to one set of outlets. Then move the lever on the tractor valve in the direction that sends oil to the IN on the splitter valve. That oil will enter the splitter valve and pass through it's "open center" and return to the tractor reservoir via the other tractor outlet. Secure the lever in that position.

Now the splitter has a constant flow of oil through it's open center valve and when you operate the lever on the splitter valve it will divert that flow to the the splitter cylinder.

That makes sense, thanks for your help. I think that will be the
cheapest way to go to get my splitter back working for winter.
 
I love the idea of a 3 pt splitter driven by the tractor hydraulics but given the price of reliable, high quality Chinese Honda GX clones, it makes no sense not to just replace the engine on your splitter.
