That's because the cheapo log splitter uses a two stage pump. Tractor doesn't have that. Most of the travel of a log splitter ram can be handled by the low-pressure, high-volume side of the two stage pump.

I agree that it might not operate very fast on system flow, but it should operate normally without the other symptoms of restriction he is describing(loader safety squealing, 3PH not functioning)...


Bill and Hillary... You crack me up:)

It will still build enough pressure to perform its duties, lower flow rate would simply make it perform them more slowly. You didn't say which model you had, the 12-ton model is made for tractors < 7 gpm, which your BX is.

Hi Copperhead,
I had a BX2230 with a log splitter plumbed to it. The smaller Kubotas have a smaller hyd pump which I believe is 4.5 gpm. Mine ran really slow, but it had the power to split anything on it. You may have to take the manual for the splitter to the Kubota dealer, and they will help you figure which is the pressure and return line on your tractor, and the manual for the splitter will tell you which line is which from the splitter. You need to be sure to have Kubota fittings on your lines, too.
Also, you may have to lock out the control valve for the FEL. You should have a switch right on top of your valve with two pictures of a lock, one open and one closed. Move the toggle to the closed picture the take power away from the FEL, this should help with the whining. My B7800 runs the splitter with a lot more umph because it has a bigger pump, but the BX also ran it fine, just slow.

The lock doesn't do anything more than lock the linkage between the joystick and valves... it doesn't touch the actual hydraulic loop.

ok, where to start...
I removed the FEL thus eliminating the FEL valve. The BX just loops back into itself for those not enlightened.
I did use aftermarket quick connects, on a earlier trip to the Kubota dealer I found my original fittings are no longer used on the BX tractors. Verifed by part number sub/replacement in kubota parts list. I used fitting from a local shop.
Before my first post I got the splitter to run for an hour, decided it was time to stack some and let the tractor take a break. When I fired it back up to finish off a few splits it was back to same, no 3ph control no splitter control.
I took the inline and outline off the splitter valve, coupled them together. Still the same.
OK I got a bad coupling???
I switched the couplers out on the splitter side of the hoses, no go.
The couplers on the tractor end work fine when you connect the tractor to itself. In fact those where the fittings I switched the spliitter ones with. Again the tractor still works when looped to itself, no go on the splitter.

I'm thinking something with the tractor itsself. Could a patially clogged Hydro filter or screen cause this by some kind of back pressure?
Of course there is always a problem with the Hydro itself.
I read alot about setting the pressure on the hydro in other post,
I plumbed a guage on the input side mostly to monitor what the splitter was doing to the tractor. When the splitter did work it read 1650 psi at max load. I don't know if this a acurate reading of the hydro setting where the guage is placed. I know the BX22 should read 1850 at optimum. So if it is a acurate reading I'm running about 200 Psi down.
I also thought about trying to hook into the FEL loop now that its available. Would this make a difference?
Sorry this is long winded but trying to throw it all out here, maybe something will ring a bell.

Quick update, I bought longer sections of hose and now run the splitter off the FEL quick couplings. Don't know why the BH loop is acting goofy but winters coming and I got wood that needs split. I'm in the process of duing the Hydro fluid change and completed the engine oil change. The hydro screen was surpisingly clean compared to past changes. I'm adjusting the hydro relief now that I got a guage to check the pressure with. I'm getting a reading of 1650. I have the shims and will adjust the relief to 1850, would be interesting if all my troubles with the splitter clear up then.

Some things are meant for each other:

Log splitters and two stage hydraulic pumps

Bird dogs and shotguns

Pancakes and syrup

Too Funny!
