Help with Farmall 706 PTO

OK, I'm sure there is an easy answer, but I feel like an idiot. My 1965 Farmall 706 diesel has what I assume are standard PTOs in the rear: the 6 spline 540 RPM and the 21 spline 1000 RPM. The problem is that the 540 PTO has a female output, but the 1000 RPM has a male output. All my equipment (post hole digger, mowing deck) also have female ends on the connecting shafts. So I can put a converter on the 1000 RPM that makes it a 6 spline male, but I understand that will damage the equipment and the post hole digger doesn't really fit well. I can't find a replacement shaft with a male end to connect to the female 540 PTO. Also, all new PTOs also seem to have female outputs. Am I missing something basic here? I appreciate any input (pun intended). Thanks all.

What you have is not standard a 706 should have a
six spline male 540 pto shaft. I don't think the
shafts on ih were reversible but you might check
owners manual. I haven't been around a 706 for 40
years but drove them a lot as a kid. Several 706
owners on the forum that can help out.

From the parts book. it shows the shaft. ahaft extension or adapter might be on it? Jim

I appreciate the replies. The output is flush with the housing, so there isn't an adapter. Does anyone know if the shaft is reversible? Thanks again.

All of the 06 series I have seen have two male shafts. Post a pic .

Just a different thought. Is it possible that the 6 spline shaft is broken off. When I was a kid I was mowing hay with our New Idea Cutditioner and it started scraping the ground. Instinctively I grabbed the fast hitch lever to raise the drawbar and snapped the shaft off. Dad was helping shell corn at the neighbors, so I got to take over there, he went home took the cultivator off the other 706 and finished mowing. Both our 706's had dual pto shafts. We never used the 1000 rpm one but it was there.

I think your 540 shaft is sheared off.

OK - here's what I have. The 1000 RPM is on top and the 540 RPM on the bottom. I think you can tell that the bottom one is a female and it doesn't look like anything is broken.

Must be broke off. I had a 706 and it had the two shafts. A pic would help.

Sorry - it took me a minute to figure out how to upload pictures. Anyway, I don't think I have a sheared shaft. Thanks again for your help.

I cant tell from the pictures, but that looks like it might be an external hydraulic pump for a loader? I only say that because of the hoses coming
off of that housing. I haven't been around many IHs, I bleed green, but I believe both PTO Shafts are flush with eachother on the back of the
tractor . Not sure if I'm onto something or not. Just a guess.

For sure a hydraulic pump. trace the hoses and if they go where you need them for a loader or a remote you use, get a male to male adapter and have at it. If not needed, remove it and you will find the missing shaft sticking into it. Jim

Looks like an external/add-on hydraulic pump to me. Does this machine have a loader or perhaps a boom type mower on it?

Yeah - the light is starting to come on. I think you're both right - but I have spent a lot of time finding a male/male adapter, but I can't find anything shorter than 14". Makes it hard to put anything on with that much shaft.

That is a Prince pto pump just slides on. The chain is for antirotation. Got loader or some thing else it runs when pto is kicked in?

Yes, there is a loader on it. Why wouldn't they put a male shaft on it? Seems like a female output makes it useless.

It's got a hydraulic pump on it. Take off the pump and you will have a male shaft.

From the looks of the hoses I don't think it is being used for anything.

The tough looking part is just a cover for the chain. The loader actually works fine. I use it for the 1200 lb hay bales when I feed the horses.

What you have is a 'Farmhand' type PTO pump. Unhook the chain and slide the thing off and you will see your MALE pto shaft.

Yes, looks like add on PTO pump is on 540 shaft. It is quite common for tractors of that era to have a PTO pump for the loader because hydraulics on tractor were slow for a loader. You should be able to slide the pump off your tractor 540 PTO shaft. You can use the PTO for something else but will not be able to raise loader up but leave it whatever position you leave it.

With a loader on it using the PTO pump you must consider the loader as inoperative when turning on and off the PTO powering the equipment being used. Jim

If that was my tractor and if the add on pump on the
pto shaft runs the loader I would not put an
extension shaft on it. Any pto work with load and
cavitation will probably knock the seals out of the
pump. I bet it was made that way to slide on the
tractor pto shaft from either direction. A 706 should
have a set of remotes under the gas tank for loader
and corn picker hydraulic hook up. That does look
like a pretty hefty loader so a previous owner may
have wanted more pump pressure to run it.

If you need the 540 shaft and need the pump at the same time consider getting a pump for the 1000 rpm shaft

Good call, Todd - I was just thinking the same thing. I have never had a need for the 1000 RPM PTO, so it would definitely make more sense to put the pump on that and leave the 540 for my implements. Thanks again to everybody.

What in the HELL-o are you talking about , all Dual PTO's on the 06-86 sires have MALE shaft out of them . And trust me i have bought and sold owned and worked on more 706's then anybody on the net and sold more of them then the three I H dealers around ever did . I have never seen a female end on a PTO ever.
Neede a picture of the arres end of yours.

Now i see the pictures and yes it has a Prince PTo Hyd. pump taking up the 540 shaft . Pull it off and stuff it on a shelf and install a 15 GPM pump in the tractor and a 2100 Psi relief . Then you have the shaft ya need for the toy's you want to play with. and yes the loader will be a bit slower but it will work , those old PTo pumps were in the 21 GPM range and not sure on the pressure on them. I did not see the picturre of the Arres end before .
