There is a difference of opinion here about how the 2 speed PTO works. I say it works the same way as my 6000 2 speed works. There is an "economy" setting which lets the PTO turn at 540 RPM at a low engine RPM and a "regular" setting which lets the PTO turn at 540 RPM at a higher engine RPM for heavy work. The same for 1000 PTO but with a different PTO stub shaft which is driven from a separate gear. The other guys say there is 1 setting for 540 PTO and 1 setting for 1000 PTO with the middle setting being "off". If this is true, the 540 shaft could be spun at 1000 RPM and that would be very dangerous. Could someone out there tell us who is right? Thanks. EDIT- this is a 981 not a 971.

i'd agree...

i included the pto section for an 881.

I know some machines have stub shafts that engage different gear clusters.. but at looking at this one.. I'm thinking it not that way with this setup. IE.. it's just a shft end swapout. though i've never had an sos pto clutch apart.. ...

the *81s had a 1000 shaft option. It's named as an NLS part on CNH's parts website. IIRC the picture shows a 540, but if look at the list for that item (I think it's #52) it lists both shaft options. Someone correct me if I'm wrong here, but I see no way that the 540/1000 shifter on a *81 would know whether it had the 1000 shaft installed or the 540.

With the 540 pto installed you will not get a 1000 pto speed with trans shifted in that position. When installing 1000 shaft the pto box has to be shifted to 1000 position to put 1000 shaft in and with trans in 1000 position then will have 1000 pto speed. I have not seen a 1000-1 3/8-21 spline pto in a 6000 only 1 3/8-6. Someone out there has one. Did ford make a 1000 pto shaft for X01 series? Theres not one shown in parts books or I have looked in rite place.

No, I didn't read/see the edited post. It doesn't show up as a reply the same way on classic for some reason. I do 99 % of my posting on classic.... I came over to the modern side to make the reply. looks like new replies bubble to the top...

I now see the italics.

what! SouNdguy! you can't read my italicized edit?

on the two shaft discussion, farmall from the 06 series through the end of IH, at least had two fixed shafts. They stayed were they were. The cautious guys moved the shield up and put a tube around the 540 when they used the 1000 and reversed that procedure to use the 540.

No contrary at all.. just a clarification. You don't know how many threads I've seen where when discussing 2 speed pto's in other forums where someone thinks thare are multiple pto stubs out the back of the tractor.

A jap tractor forum I hang out in, that happens constantly.. people pop in and ask where their 768 and 1000 rpm stubs are as their side shifter has a 540, n, 768,n. and 1000 selector..
Larry.. my point was that there was but a single pto shaft.. not 2 shafts sticking out.. one 540 and one 1000 some tractors DO have 2 pto shafts available!!!

Yep - I've seen two pto shafts sticking out of JD's and IH's...though one of them had the un-used shaft 90 degrees to the one in use. I -think- that was the green ones, and IH had the 1000 shaft above teh 540. But I don't know if you had toswitch them around, or they were just higher.

Once again I have been proven wrong by more knowlegable people:) I wonder if the 6000 is the only tractor Ford made with the "economy" PTO option? It does come in handy for me when doing light jobs like brush hogging. Running the tractor engine at lower RPMs does save a quite a bit of fuel over time. Thanks for the replies.

6000 is the only Ford I know of with the 'economy' pto setting. Seems like I've read about a NH model(s) with a similar set up. Some David Brown models had a similar option in the '60's/'70's.

Although I've never had a lot of experience with an 81, my understanding of what happens is this:

There are two shifters on the left side of the transmission. One shifts the drive from the 540 to 1000 speed setting and vice versa. The other shifts the drive from the engine to the rear axle and vice versa.

Thus you basically have 3 PTO options, 540, 1000 and ground driven. The latter varies with the speed of propulsion of the tractor.

I do not know that there's any sort of engine speed governing on these units other than by the throttle lever.

The PTO shaft stub is hollow on these units. I believe it is retained on the shaft by means of a set screw or set screws. Contrary to what souNdguy says, there are two different stubs. well, now that he edited his comment . . . One is the small 1000 spline and the other is the 540.

An operator could theorectically couple a 540 implement to the 540 shaft stub and engage the drive in the 1000 speed detent. I don't recommend doing so, however.

Your friend is right and there are 2 different stubs.I believe the splines are different between 540 and 1000.The neutral position is used when you use ground speed setting.At least that is how it was on my 981.

yer pto revs are a fixed ratio to the engine revs, based on gearing..
you have 2 settings for the pto.. thus a range of pto speeds, available thru a range of engine speeds.

but there is only 1 pto stub.. (edit for clarification ).. there is only 1 stub out of the tractor at any one time.. not 2 stubs sticking out at one time ).. that wasn't clear in my prev post... seeing vito's comment , I can see where confusion would occur )
