Purchasing B2650HSD with attachment question

BCWoodtick · Feb 21, 2015

New to this forum, and have a question about the B2650. I see that the Hydraulics will put out 5gpm but what does that translate into PSI. I am going to purchase a 3 Point wood splitter and want to make sure that it will work to what my needs are.
I will be splitting Fur and Larch but up to 36" diameter at the buts. The splitters I am looking at will be 15/20 ton or 25/35 ton based on 2550/3000Psi. The specs on the Kubota page don't specify this way.

Any help would be appreciated.
Thanks

PSI relates to force (power and is different to GPM. The 5 GPM is related to flow (speed) which I don't think you would be happy with. I tried looking up psi for your tractor but fail... My guess would be it's around 2000 psi but I'm sure J_J will be by to school us!

You have the same flow with 15 ton splitter or 25 ton... difference is it takes longer to fill the larger piston. The amount of force (psi) the tractor will be able to give will be the same but the 25 ton piston is larger and would give more power. (not sure why they don't list psi at kubota?) Clear as mud?

I found the specs on the splitter and the 25/31T requires 13 gpm so I am guessing that will not work with the 5 gpm on the B2650??

Is there any other options as would be nice to have the implement to make life a little easier?

I am sure looking forward to getting the B2650!!

There is a thread on here discussing 3PH splitters and stand alone gas powered. We used a 3PH for years, but now much prefer the stand alone which doesn't tie the tractor up and just seemed like a waste to put hours on an expensive tractor to split wood.

You can use a rear hydraulic pto pump... this one is 11.4 gpm but there are others out there with more gpm.

Hi and welcome to TractorByNet! I have moved your thread to the Kubota forum where you can get as much information as possible. Best of luck! :thumbsup:

So the salesman I am looking at purchasing the splitter through is telling me that it will still work with my low 5gpm hydraulics. Is this the case as I wondering how 5gpm can supply something that the splitter manufacturer says requires 10gpm for the 15/20 t and 13gpm for the 15/31t which is the one I would like to get? Still leaning towards going with the 3ph as it will work well for my requirements.
So 2 questions I guess : Will it work without having to buy a PTO pump?
And if it will what will the draw backs be? (thinking slow cylinder?)

Thanks

teg · Feb 22, 2015

yup, find out how long it says it takes to complete a cycle... now double it. What wood splitter are you looking at? any links...

You can start a new thread asking how happy are you with a 3ph wood splitter?

I couldn't agree more with the hour issue being put on a new machine with a stand alone splitter being fairly cheap . If you are going to have a fel on the tractor it can be put to good use , like putting that split wood in the bucket as you split it or moving those big cut up pieces closer to the splitter . I did that for a good many years and that fel saved me much work for sure .

Thanks for the input guys.
I get the impact of having on the tractor and just not sure if an extra 5-10hrs a year is a big deal? I will have a fel and the BH77, and already have the splitter included included in the pricing so just need to finalize my decision before delivery... lol

I also have a little JD 425 with a large wagon so needing the fel isn't a big deal. I think the real kicker is if it will work well enough with the low GPM's??
If not maybe switching to front forks with grapple might be better way to go and wait till I want to spend more on a stand alone??

Teg, the dealer said I could just hook up into the BH lines and wouldn't need the rear remote, but I am getting the front remote installed in case I want a grapple option later down the road.

from memory, the b2650 has about 9gpm, i remember asking this when i reviewed the fel lift and roll vs jd 2025. i think the b2650 has 2 pumps, but should check with dealer.

You are correct....the gpm for the 2650 and 3350 is 8.7gpm and yes it is dual pump.

In my opinion the splitter will work fine. I had one on a B1700 a few years back that split fine but was slow...the B1700 was about 4.5gpm if memory serves me right.

Hooking up to the BH lines is the way to go.

Dual pumps, yes, but one is dedicated to power steering and not available to run any implements, so I'd guess the 5 GPM is what's available to run the splitter. The amount of flow (GPM) of the pump only determines how fast the cylinder will move and does not impact force which is a function of PSI and the area of the cylinder under pressure - bigger cylinder generates more pressure due to more area the PSI is applied to.

Your 2650 will run either splitter, but do the math and figure out what the force or tonnage is going to be. If your B2650 puts out 2000 PSI max, multiple that by the area of the cylinder which would be Pi R squared. So a 4" cylinder would have a radius of 2" multiplied by Pi (say 3.1416) = 6.28 square inches of area x 2000 PSI = 12,566 pounds of pressure, or 6.25 tons of force. If my math is off, I'm sure someone will "fix it" for me. LOL

So looking at that my tons of force won't be anywhere near the 25-31 Ton that I would want?

Looking at some of the other threads JJ recommended using this valve "Model LS3060 Rapid Extend Log Splitter"

Has anyone used it and is it connected before the splitter while still using the valve that comes with the splitter?
I am new to the whole Hyd. line thing and wondering how easy it would be to install?
Looks like it would be the way to go as he states will take 4gpm and convert to about 24gpm.

Thanks

There have been several threads on bumping up hydraulic pressure on Kubotas to maybe 2400psi, via shims, and as the others have posted, yes, pretty much any tractor will operated a rear splitter, but don't expect the ram to be quick. A quick look at Tractordata says you will have 5gpm. Not a lot for a big splitter.

I'm not familiar with that valve though it looks interesting. But, you have to replace whatever valve comes with the splitter with that one at extra cost.

As a point of reference, I ran a small splitter off my BX a few years back. The BX has about 3.5 GPM and 1,800 PSI +/-. Not a lot of force or speed, but it split 90% of what I needed split (didn't try to split any 36" however). What I used back then was a two-way splitter that splits in both directions so you don't have to retract the cylinder before splitting the next log. There's quite a few models on the market that are two-way. Mine was a Northerntool Powerhorse model. That's one way to "speed up" the process to compensate for the low GPM.

As was stated, you could adjust the pressure on your B2650, but you'd be looking at adding a few hundred PSI before you are pushing the safety limits of your system, and you might void your warranty if any hydraulic parts should fail. But, like I said, most times you don't need the full tonnage of any given log splitter.

Here's a link to the DR dual-action version, but there are others out there, just can't recall the brands off the top of my head

Just recalled another brand - Split Fire. They sell 2-way 3PH splitters also.

Well I think I like the dual action on splitting in both directions, thanks for the info as I am thinking about holding off on the splitter now wait and see how easy the BH77 will be to take on and off.

When I do get splitter I think I will go with that dual action. Will just have to decide on the 3PH or stand alone.

If anyone has used the LS3060 Rapid Extend Log Splitter Valve would love to know how easy it is to install on the 3PH splitter?

Thanks again for all the info, just can't wait to get the B2650 now.... hopefully next week?
