PTO purpose?
 

I have seen pictures showing some earlier model cubs with a spline shaft pto oud the rear end. I have always wondered what they were used for since i have yet to see a picture of one n use. Was it just for novelty and how do you engage it? It cant be a live pto because it seems as its only offered on gear drives. When the clutch is pushed in one would think the pto would disengage?? Just a very curious enthusiasts

My cub cadet 122 has the rear pro but I have the same questions, I have seen people make pull behind mowers that are very cool, pto powered

Yes, a rear PTO was offered on gear drive cubs through the quietline series. Then, only on the SGT later on. You are correct, the clutch would disengage the rear PTO, but it is still considered "live". It technically is a "non-independent live PTO" as it couldn't run with the clutch disengaged. On large tractors, there were two speeds of PTO's available, 540 RPM, and 1000 RPM. I'll get to that in a minute.

Harvester didn't make many attachments for the older tractors, if any, that were driven off the rear PTO. It was offered for the purpose of being used on the farm. I know of several farmers that used their cubs to run augers, bale elevators, water pumps etc. The biggest problem with them was, because the transmission was taken from a Farmall cub, then had a gear reduction added to it, and a smaller motor, this made the rear PTO turn in reverse to it's larger tractor counter parts. So, it made using the PTO more difficult, as you either had to reverse the drive on the equipment you were going to use it on, or buy a PTO reverser that was offered mainly by M&W. These reversers are hard to come by and can be quite expensive. But, they allowed the user to utilize the PTO as it should be. The M&W reverser also utilized the standard size 540 RPM PTO shaft as it's output. The PTO shaft on the back of the cub was a smaller, less common shaft.

The ones offered on the SGT was slightly different. It was an "independent live PTO". It did turn the correct direction, however, it ran at 2000 RPM and used a very odd female output shaft. Adapting and using these PTO is difficult as finding the correct shaft for the equipment is hard, and they turn too fast. But, IHCC/CC did make mowers and tillers for these tractors.

Some people consider them only good as a novelty. I, however, disagree. If you build equipment that can be run the direction that the PTO turns, or have the knowledge of how to make it work, they are EXTREMELY useful!

If you would like to trade parts or rear ends ..... I would be interested. I would like to have one for my 1000.

I'm pretty sure the revrrsers were made by Hub City and not m&w....could be wrong tho. I made a rear mower out of a cub cadet original mower deck. Never got around to finishing it though. It would have been cool though

Jmech- I would like to keep my pto rear as I am interested in making a rear mower for it I have some skills and patience and would like to try it, although there is a pro rear for sale on craigslist in my area I believe it's the same guy I just bought a qa42 from today actually, he has a nice pile of cubs and all small engines I wish I would of seen inside his shed but he said he had someone from wisc coming so he couldn't show us, he said he had a 122 with hard cab as his pride an joy also a few bolens, allis, vintage Briggs, hitnmiss, etc said he was downsizing. There's my little story for the day.

oh and my pto has a sleeve thing over it, looks like an adapter for standard style pto splines.

I have a rear pto on an Original

I have heard another story for them

don't know how true it was

taxes if it had a pto it wasn't taxed

I bought a farmall cub rear belt pulley form mine (still need to get it on but...(

My Hawk-Bilt groundsaw uses the rear Cub Cadet PTO to drive the tractor when it's digging. You disengage the clutch, and there's a hydraulic motor that turns the rear PTO. With the tractor in gear, it will move the Cub Cadet forward while it's digging. It's a pretty neat setup. If you don't keep the clutch disengaged, the hydraulic motor "fights" the tractor motor.

And, when I bought a Massey 1528 a couple years ago, I was told it had what was called a "live" PTO because you could shove down the clutch to stop forward motion of the tractor and the PTO would still turn, i.e., it was still live. If you depress the clutch all the way down it stops the tractor motion and the PTO. On the other hand, my 300 International has an "independent" PTO. The lever that controls the PTO has no effect on the motion of the tractor and doesn't require using the clutch. I don't know if that's correct for the terminology, but that's what I've awalys been told.

Do you have any pictures of the Reverser or what a person needs to look for when trying to buy one? I have a 100 with rear PTO and would like to find the rear pulley attachment to run a hammer mill at our tractor show.
Thanks

Here is a picture of a Hub City Reverser...

Should of Just asked me bud a I would of explained it to you. Lol

The rear PTO was added to operate ice cream makers, nothing else!! :bigthink:

:biggrin2:

Well I would have been wrong!!!
:bigthink:

I might be wrong too, but, it is the only use I have found for it!! :bigeyes:

:biggrin2:

Did the farmall cub have the unusual splines or standard splines?

The F-Cub and the Cub Cadet used the same parts.

Thanks for the picture Roland.

You don't need the reverser to put a belt pulley on. It mounts over the existing PTO. They sell on e-pay pretty often.

Rear PTO
 

Am I glad I found this post. I have a 129 with the hydro drive. The 129 does not offer the rear PTO, but I am in the same boat that I would like to power attachements with the read PTO, such as a small rotary mower. I have a Ford 8 N that I use for some of these projects as I have roughly 10 acres to mow and continously landscape - I plan on making a little 3 hole golf course next summer. Having a little tractor like this is proving very useful and easier than manhandling some of the attachements that I have for the Ford.

I plan on replacing my current rear end with a 1650 read end - as this has the rear PTO, but was told the same thing. The reverse. I have been wracking my brain all week on how to get one that will work or find a skilled fabricator that would tackle this. I know its not gonna be cheap, but I love tinkering with these little tractors. Very handy.

The 129 I picked up this year is in extremely good shape, with a fresh 14 hp Koehler. I like the engine, but of course, at least for me, I want more HP! I just put a down payment on a 23 hp Briggs and Stratton Vanguard. That should give it some snort. These little tractors are neat and NO flimsy fiberglass to be found.

I'm pretty sure the rear PTO only came on gear driven tractors. So swapping rear ends wouldn't do anything.

If I understand how they work correctly (and I may not) you bolt the PTO onto the rear differential cover and it runs off the gears on the rear differential.

However, there is a shaft on the rear of the hydro pump, and perhaps it could be adapted to run a rear PTO. Anything is possible with a welder and some skills :D

Or, since it appears you're willing to spend some money on it, find a gear driven tractor and go from there.

nonetheless, thanks for bumping this thread. I learned a lot from it.

Here is a video of a 70 grinding corn.

We told you in the other thread, swapping rear ends is a waste of time. A 1650 rear end is EXACTLY the same as the rear in your129. No different at all. You cannot put a rear PTO on a GT (garden tractor) that is hydro drive. Can't. You can on a gear drive, but that's it.



You will have to kill the tractor to put a Vanguard twin in it. You will have to hack the frame all up. There is no need as a 14HP single will perform just as well. You won't need any more horses.



You just need to go use your 129 as is, then you will understand. But.... you can't put a rear PTO on it.

No. You don't. The rear PTO on a gear drive sticks out the back of the rear housing, but runs off of the top shaft in the trans. The PTO on the rear of a SGT (hydro) runs off of the output shaft on the back of the hydro, and simply bolts on the rear cover.


All hydro's have that shaft. Issue is, the shaft is not splined for the coupling for a rear PTO, and the battery box is too low on a GT to get the parts under it. So..... that is why they are all on a SGT. Oh, I'm sure you could hack it all up and get one on it, but it's going to take more than a hydro pump off a 1650 (which won't work with a rear PTO anyway) and slapping it in there, doing some "custom crap" and going about your day.....


If you really, really really want a rear PTO, this is your best option.

BUT, remember, your going to have to build your own attachments.

You bet bet is to get a tiller gearbox that mounts to the rear end.

That's the correct answer!

I don't disagree with this logic, but what's he gonna run with it other than a tiller once he gets it on there?

Maybe he can mount this to the back...

Trying to remember. Wasn't there a member here who fabbed up a gear pump to run off the output shaft of the hydro? Not sure if it was to add maybe power steering or hydraulic powered attachments on a narrow frame? It's been a while.

I can't answer that but if someone is determined to drive something in the rear, that's the easiest way.

Dale, (Merk) has a tiller gearbox mounted on the rear of a tractor turned so the output shaft faces the rear. He drives a sickle mower with it. Actually, he may drive a finish mower with it too..... I'll dig around and see if I can find his pic. :bigthink:

The rear mounted mowers are my Dad's creations.

Dad is using the tiller drive facing towards the rear to run Hadan mower. The tiller manual has instructions in the manual to do this.

Dad is using the 90 degree box from a IH Cub Cadet 1100.

pretty cool attachments Merk.:beerchug:

I believe you are right, I want to say it was a hydraulic pump, but don't remember for sure. I think it was only a couple of years ago.

Was it the guy who built the cab onto a 147 that had all kinds of cool features, like heat?

It would probably be easier to do on a Narrow Frame because of the battery location.

I would like to incorporate that shaft to run an alternator that would produce enough power for an electric heater.

Thanks

Talk about weird shit... for whatever reason, I reverted back to my " how to put a 540 pto on a gt" thought this afternoon and then I get on to see this post. After exhausting the mechanical means, I came up with... Hydraulics. Which btw, it appears that a planetary gear set up is the only way possible if looking to go with the 540 RPM standard.

Surplus Center has LSHT motors with the 1-3/8" "540" shaft already on the motor its self. Then find the correct displacement pump to drive said motor. I have not figured out the details except the way it would be driven (splined output shaft of hydro pump). One of the first issues I see, little to no room for a clutch of any type to disconnect the hydraulic pump. An open center hydraulic valve would need to be installed in the circuit, but would continuously circulate oil.

The valve, if directional, would be very handy if a guy wanted to reverse the pto (post hole digger operation), but not necessary for a gt.

The next issue is oil... there is not room to have a separate oil reservoir, SO the rear end would need to be tapped into for a suction and discharge for the pto ckt. Which, to me, presents the biggest problem, Oil Temperature. Would the oil, after being used to for auxiliary hydraulics and propelling the tractor, become too hot with the extra pump and motor added to the oil system? I do not see a feasible way to install an external oil cooler that wouldn't just look awful on a cub.

Any thoughts?

I think you might be thinking of my 147 FEL thread.
