Kubota BX2200 - 3point log splitter

[apfaff]

I am trying to plumb a log splitter into the hydraulics on my BX2200 and am not getting the pressures I expected (~1900psi). I tapped into the manifold block behind the left rear tire. This block goes to the front end loader. It has 3 ports: to implement, from implement and return. I used the 'to implement' for the pressure port and have tried both 'return' and 'from implement' for tank lines. The splitter does not appear to build any tonnage. I have not checked pressure yet, but I assume that it is very low. 1900psi should be more than enough to split logs (although it will be slow because its only 5 GPM). I have two questions:
1) Has anyone ever hooked in and if so what ports/locations should I use for pressure 'in' side of the splitter?
2) What is best port to use for the 'out' side of the splitter?

Thanks in advance!

I just checked the pressure and it was only ~170psi. I also tried connecting some of the ports on the loader controls (my loader is not on so I thought that might be the problem). No luck....

DId you dead-end the hydraulicks by turning on the engine without a complete hydraulic loop (pressure + return)???

If so, the hydraulick pump may of had no place to pump the fluid to, building up pressure in the pump and eventually destroying something (seals, casing) resulting in little to no pressure afterwards...

I hope this is not your case...

I believe that there is no Pressure Relieve valve at the Manifold by the rear wheel... THe loader has one...

Once the log splitter reaches max travel, there will be no more fluid flow, unless your control valve (splitter) has a Pressure Relief or a bypass Circuit...

I had a 3 pt. logsplitter on a BX2230, and hooked the lines from the splitter to the lines that came off of the tractor for the FEL. Pressure was enough to split anything that was put on it, but with the low gpm output of the pump, cycle time was pretty slow. I now have the same splitter hooked up to a B7800, same impressive splitting pressure, and a quicker cycle time due to a 9gpm pump.

The hydraulics shouldnt be dead-headed because I used a T-fitting to tap into the lines going to the FEL.

Shantycook...
I'm attaching a picture of the small manifold block going to my FEL. Does this look the same as your BX2230? Which lines did you use?

I used the bottom line coming off the manifold block for the 'to' splitter and the tried both of the others for the 'from' splitter. I am only getting ~170psi from the pressure line. The two return lines were at 0psi.

Thanks for any help you can give!

I'm confused!
If you put a tee on the pressure relief valve by the manifold, how are you suppose to get any pressure to actuate your splitter?
when the control valve on the FEL is not actuated the fluid gets dumped to the bypass / return (i forget which). When you put a tee on the Pressure side, fluid will follow the path of least resistance - the bypass on the FEL control valve: you should barely get any pressure at the splitter.
You have to hook the splitter in Series with the FEL controls - Power Beyond.

There is your problem...You CANNOT "T" into high pressure hydraulic lines, all new valves (like on your logsplitter) must be plumbed in SERIES to get pressure. The fluid is take the path of least resistance the way you have it plumbed. The only line that can be T'ed is the low pressure return-to-tank line.

You need to create what's commonly call a "power beyond" loop to plumb the splitter into.

You you do a search on "power beyond", you you get hours of reading on this subject...not being very familiar with the Kubota's I cannot tell you exactly how to do it.

But basically you need to take the OUT of the FEL valve, to the IN of the new valve, then the OUT of the new valve to wherever the OUT for the FEL valve was. When the splitter is not connected you MUST connect these lines together as they have the full flow of the pump going through them whenever the tractor is running.

BINGO!

Pat-which log splitter make and model do you have? I have been considering one for my B7800 now that I have a valve kit on my tractor

Thanks everyone! I hooked the pressure line up just before it enters the fel controls and disconnected the fel completely from it. It worked great! Like you said I just need to make sure I connect the fel back in whenever the splitter is disconnected so it doesnt dead-head.

Bottom line, the fel control valve bleeds the oil to tank when the handle is not being used and in neutral position.

Only remaining question I have is which tank line is the best to use (there are two). The 'from implement' or the 'return' line? I assume only 1 goes through the filter, likely the 'from implement side'. Does anyone know for sure?

Thanks again
