Log Splitter question

[Cysco]

I am really green on hydraulics so be prepared as I will ask a lot of questions if I don't understand.
I have a Kubota 4610 tractor with a factory loader. I havd a remote installed by the dealer to operate a tilt scraper . My question is how do I get constant pressure back to the splitter control valve without having to "hold" or "tie off" the control for the remote. If you need more info I will get it for you.
Thanks for the help.........

Welcome to TBN


A bungee cord or rope is the cheapest solution the the problem.
If that does not appeal to you, then you will need to create a "powerbeyond" loop at the rear of the tractor. PowerBeyond is a set of hoses (one IN and one OUT)that has constant flow of hydraulic oil when the tractor is running and ALWAYS needs to be connected(either together or to an implement with a open center valve like your logsplitter) To plumb this, you will need to determine if your existing FEL valve has a port marked "PB", or you can count the hoses connected to it and report back. If your valve is capable, then I would guess you will spend about $200 to get it plumbed.

Just a word of caution.... When using a power beyond circuit only hook up to it when the tractor is shut down or you will fry your pump. I have one on my tractor to run my log splitter. When not in use I use a short piece of hose to complete the circuit.


Like stated before the circuit always needs to be completed. In my case if the log splitter is out of the circuit I use the piece of hose.

I run a Prince pump for my splitter dedicated to that job for 2 reasons. One it gives much more flow than the tractor pump and second it saves wear and tear. I get a 6 sec cycle time with that pump, 22 GPM, if I'm at full 540 PTO RPM. Most of the time I run the engine at 1500RPM.

That's a nice clean setup, wkpoor. Well thought out - I like the receiver...

Thanks for the info. I tried the bungee cord and it does ok. Cycle time is acceptable. I liked the Prince valve on the PTO but having to cope with the fluid tank and the cost it would be to much. I have the ports to do the constant pressure and will probably try that as my first option when the bungee cord breaks and slaps me in the head. Thanks for the good information. Ya'll have been very helpful. Have a good evening.

You should never run a QD on the suction side of a pump.

Is that a pressurized reservoir? I just cant see any other way to avoid cavitation at 22GPM with a restrictive suction circuit like that appears to be. Maybe the tubing and fittings are MUCH bigger than they appear to be. Quick connects cause a lot of turbulence and pressure drop. 22GPM is huge delivery thru restrictions when youve only got a few psi loss [14.7 max] allowed.

I understand the concern, however how would one remove it conveniently from the tractor? This unit has been in operation for 3yrs now and used year around with no ill problems I know of. The suction side is 1"

This is not a bootstrapped system. However the tank is vertical in nature on purpose to maximize flooded suction. Prince made no mention to me that flooded suction wasn't adequate for this application. And again it has been tested....alot.

Probably your saving grace is that you are running this pump below it's rated rpm. On the suction side, I would look at the wet line couplers like the huge dump trailers use. I don't know if they can be used on the suction side, but they are more reliable in your suction application than what you are using. The style you use do a good job of keeping fluid in, but not at keeping air out. They seal on the same principal as a hydraulic cylinder. I would also consider a sweep elbow on the suction side rather than a hard 90. All this being said, the setup works. So, what the heck do I know? Maybe not much.
