Kubota B6100- ver - Riko A11 V SB petrol

[Jesse]

Evening all budding wood munching entrepreneurs , techno question, I am running a Kubota B6100 at the moment which is a great little tractor, no complaints, How would it compare to the following set ups.

1 Kubota tractor running a Riko A11 VPI from the tractor hydraulics

2 Kubota tractor running a Riko A11 VC from the PTO

3 A11 V SB Petrol running as its own independent unit

I am not sure of the pressure or flow rate produced by the Kubota

I believe the Kubota HP at engine to be 14 HP and at prop to be 12 HP

Which will be the quickest and have the greatest squeeze

Be grateful of any advice.

 

Should've said its the b6100 I want to power the new splitter

I can't remember exactly but I fear my old 6100 did not have a continuous pump circuit. In any case whilst the pressure would be fine it is unlikely that the 6100 will have the flow rates to keep you happy.

 

Beware the PTO rotation. Depending on where it was sourced from the B6100 did have a CCW pto - a legacy of the Japanese standard rather than the rest of the world cw standard. On a new unit Riko can tune the pump to the hp of the tractor so they should be able to advise on whether 12hp will suffice.

 

The other consideration that springs to mind would be moving the splitter. I doubt this tractor could lift a decent splitter on the 3pl without rearing up.

 

Our 7100 couldn't even lift a pumpkin:

On a tractor that small, I'd steer clear of a tractor hydraulic splitter, even if it somehow has enough flow and/or pressure (I'd guess it won't), it probably won't have much oil capacity either.

 

PTO would probably be better, but on those tiny tractors often the geometry of the linkage doesn't always suit implements sized for more conventional tractors, but you might be able to get a remote pump (so the pump slots onto the PTO rather than having a shaft from the PTO to the pump) which might help.

 

Petrol would be the safest bet I reckon, though I dunno how it would compare speed wise.

 

In theory, both the petrol and the pto should give the same "squueze" even if the speeds are different.

Thanks Marko, Chris, i know what you are both saying, i have run the machine for a number of years with the attached pto log splitter on, with 3 front weights its been fine, front wheels stay on the ground, and it is a bigish splitter, just a little tired, It also works faster than most other splitters i have seen in action, and has a better squeeze than when i ran a hydraulic splitter from a mog, i also run a topper in the summer thats why its not on now. My thinking was to replace and try and keep the weight down but not to loose any of the power i enjoy with the current set up. One big benefit is on large sites i can spin the kubota all over the sites with ease, an A11 petrol looks to be hard work, i like the bench setup of the A11 so just thought one powered of my own hydraulics could be an option, I my try and pipe the Kubota direct to the current splitter to see first what the speed and power is like.

Hi Jesse,

 

you'll not be that impressed with an A11 on the hydraulics on your tractor, definately go PTO.

We will have to allow for the HP of your tractor when speccing the hydraulic pump but that is no problem.

We have fitted splitters on the B6100 and 7100 series with no issues (I actually have a B7100 myself).

Hi Jim, what's the weight of the A11 VC Tractor PTO and how does it matter what HP the tractor is in relation to the pump on the splitter ? is it just not a one for all ? or is it the faster the pump the greater the engine will dump on a small engine.

[JimE]

Hi Jesse,

Weight is listed at 250kg for the PTO version.

The standard pump needs 20HP to turn. So if you have less HP we fit a smaller pump that produces less hydraulic flow to reduce the HP requirement. The net effect of this is that the splitter runs slower, but still produces the same power.

If we connected a standard splitter to your tractor it would stall the tractor when you were splitting hard logs and also make the engine work really hard.

Even with the smaller pump needed for your tractor to run it, the splitter will still be a little faster than the petrol version.

Thanks for looking into it Jim, are you sure that weight is correct ? the equivalent Thor Mignon 23.HVP.FT is 143kgs and i thought the A11 v sb was around 165kgs and thats with an engine ?

[JimE]

Fairly sure yes, the petrol model is about 250kg as well. They are seriously well built machines! Alot of the body is 10mm thick plate.

I'm only going by the factory book to be fair, but I can believe they weigh every bit that much.
