540 to 1000 rpm pto conversion

[Adelynn]

Hello, looking for help with a possible project. We were advised to get a pto adapter to convert from 540 to 1000 to run our spader (Imants SE115RH). Our tractor (Kubota m5660) doesn't have a creeper gear which means we are spading to fast and not getting the outcome we want. We're hoping that this conversion means we can run the tractor at a lower rpm while still getting the pto output we need to run the spader. Has anyone done this, is it possible? Also I've had no trouble finding an adapter for the pto shaft, is there an adapter out there for the driveline? Is the solution for the driveline issue to be to get a new 1000 rpm driveline and an adapter for the implement as well or is there a cheaper work around? lol Thanks for any input/help!

IMHO if you can get the engineering right it should work as a 115 probably needs somewhere around 15kw (depending on soil type/spading depth/moisture content etc...) and you Kubota has more than 2x this available.

no clue on how to get that engineering done though.

good luck and post pic's when you get it done.

This is going to sound real harsh but that's the wrong tractor to try and do anything with.
It's an SU model that has many features unavailable.
Things like a creeper gear add on or a PTO conversion do not exist for that tractor.

Would using an adapter work on the existing pto shaft? Or is a different tractor the only option? We have a Kubota L4400 as well.

An Adapter is not going to change the gearing internally which is what is required to make it work at a lower engine RPM.
Your trying to turn the PTO twice as fast then slow the RPM's down on the engine thus the PTO runs 540 and the drive will run at a slower rate.

Is the L4400 a gear drive model or hydrostat?
Hydrostat would be no issue because that will creep.
and thus the 540 will work and give you the right ground speed.
The L4400DT does not offer a creep or 1000RPM conversion either.
So you're in the same situation as your M with it.

I do believe only the M's offer 1000RPM PTO's
And you need an M that's not a SU.

What you need is an M with a creeper gear.

I'm reading the original post that he needs to turn the 'spade' faster, so YES, a 540 to 1000 'increaser' would work. It'd take the 540 PTO rpm and 'boost' it 1000, and change the PTO shaft splines as well.
Essentially it's gearbox that has a 4" gear on the tractor PTO shaft and a 2" gear on the output shaft.
OK, really you need 1.85:1 but 2:1 would be fine, tractor RPM would be slightly less.
Pretty sure someone makes such a gearbox, though have to check HP rating of it.

Thank you! I figured it would work or else why would it be sold lol. I just needed to hear it from a few people with experience. I'm not sure I quite understand what your saying about the gear box, but I will figure it out!

well here's 1 version...

seems it can be made to go 1000-->540 OR 540--->1000

lots of hit for 1000--->540
few for 540 --->1000

but it can be done, even a backyard bodger could make one.... the starting point is HP needed, then choose gears/sprockets as needed...

I hope you share the results if/when you get this assembled. I must admit I'm curious as to how all of it will fit together.

 

[GreensvilleJay]

FWIW gears/sprockets with teeth like 22:12, 30:16, 45:24 are 1.83-1.875 so 'within spec' for the speed up conversion.
57:30 is 1.9, closest I have with my MECCANO gears.

An external PTO increaser is really not an option.
A reduction gearbox CAN NOT be used as a increaser, you will explode the unit!
I don't know of any one that make one to go 540 to 1000 RPM.
The only model I can find is 1:3.8 (540RPM to 2052RPM) and it's limited to 13HP.
They are made to run pumps and that's about it.
Other larger gear boxes have the inherent problem that the direction changes, not what you want to happen.
Building one, well you better have some skills, it's going to be tough to get the ratio and the HP requirement right along with the fact that it can not be dry run it will need to be oil immersed, so your talking a wet set up.
Older Kubota designs have them cooled by the tractors hydraulic system.

I had to Google a "spader" since I've never heard of such a thing. My M6060 has the 540 to 1,000 PTO option offered by Kubota, but as @North Idaho Wolfman says, it's not an option for the M5660. I have creep range but opted for the 540/540E PTO since I don't need 1,000.

540/540E does drop rpm by 300 or so running in 540E, but that's probably not enough of a drop for the op's needs. Very interesting problem and thread. I hope the OP reports back with the solution.

I also had to look up what a spader is. Those aren’t cheap. I hope the OP finds a solution.

Any opinions on using a hydraulic motor?

You don't have enough hydraulic flow to run a PTO hydraulic motor.
It takes about 4 times more GPM than your tractor is capable of.

gee, in my #8 post... from the link...
" As an increasing ratio gearbox it will increase 540 rpm PTO shaft speed to 1000 rpm. "
it's also good for 120HP..
that's just ONE that I found.

also ,every windmill used to generate power has an 'increasing gearbox'.
OK..not 'common' but they do exist....
I looked into this some more....15KW =+-25HP, so #80 roller chain would work,still would need to know the real HP the spader unit needs. A backyard bodger could grab a couple tranny gears and make it work.

I have never increased a 540 PTO speed to 1000 PTO speed but years ago I ran a Hub City gear box on a JD 4840 1000 PTO only to have 540 PTO. Back then all our equipment was 540. It work well but it was a big gear box mostly in the way. I think back then it was a couple thousand dollars for the gear box. Hub City and a company called Rodono Industries made them. You might contact them and see if they could help you with a custom gear box. Its probably just time to buy the right tractor for the job.

I doubt you could buy 'the right tractor' for $2000 but you can make the 540_>1000 gearbox for less than that, depending on your skill set and 'stuff in shed' !
