Kioti NX5010HST
I have a NX5010 HST. I ordered a rugged made three point log splitter. Just wondering if anyone knows what the hydraulic flow is at the rear remotes. I can't find any specs on this. I know the total flow is 17.9. But not finding anything on what the steering uses or what is available at the remotes.

The splitter uses very little flow, as they dont move fast. I wouldnt worry about anything. Alot of portable splitters run on 8 hp motors running small hydraulic pumps. My home made splitter runs off my 45hp kioti using 1/2” hydraulic lines. Fast enough for me that i still have all my fingers.

I just got a used three point log splitter and I wonder how slow it will be.

I’ve thought about a PTO driven pump and tank which would allow me to use my older IH tractor without remotes. This would also free up my loader tractor to move logs.

I've always wondered how much flow the steering priority valve diverts when the tractor is sitting still, powering a splitter.

None on tractors with a dedicated steering pump and another for the rest of the hydraulic system.

Accordingly to the service manual, the NX5010 has a 14cc hydraulic pump for the loader/remotes/3pt circuit. At the 2600 engine rated RPM, that's about 36.4 liters per min or about 9.6 GPM without accounting for the hydraulics losses. In reality, that's more like 8.6 GPM or so, at 2600 RPM.

The steering has it's own pump and it's irrelevant for this application.

Further more, at 2600 RPM, it will take about 9 secs for that 4" ID cylinder to extend the 24", albeit, they limit the stroke at 20", so about 7.7 seconds.

Having ran my splitter from the remotes, I've zero interest on having that engine screaming for no reason. I used to run it at about 1500 RPM or so. That cuts the flow down some and make it operate slower.

Also, looks like the pressure for that tractor is set at about 2600 PSI, so that 4" cylinder will have 32600 lbs of force. Not quite the 22 ton they list.

For some reason it takes a special level of not-paying-attention to get the fingers between the blade(s) and log, but it is much easier to pinch them between the log and the beam end.
Definitely not a job for anyone with ADD or someone who has no fear of a PTO.

The most common configuration of standalone splitter uses an 11 GPM pump on a 4" x 24" cylinder, for a full stroke time of 11-12 seconds. Painfully slow, IMO, not everyone is as impatient as me.

Running it off tractor hydraulics is usually going to be even slower, but again, some don't mind. Running off a PTO-driven pump would be much faster, but of course requires a splitter with a suitable reservoir (eg. 1/2 gallon per 1 GPM), for that to work.

Where I fail to understand the appeal of a 3-point splitter is that it ties up your tractor while in use. Now you need a second tractor to move logs, and bring them to the splitter!

It doesn't really need priority valves.

The smaller pump will make its own hydraulic circuit that only feeds the steering and on some tractors the PTO valve too. It just shares the fluid with the bigger pump that handles the loader, remotes and 3 pt.

Pretty sure your Hurlimann is the same way but could be mistaken with the newer model after yours.
