I am completely new to this old tractor business. I just bought an old Ford today and I am trying to find out exactly what I have bought. The fellow I bought it from didn't know much about it. I was just looking for something to dig post holes with and level some dirt. Anyway, on the hood it says ford 801 select o speed diesel. On the left side of tranny it says "NDA4024B 1" with "DIF" directly under it. On the right side of tranny it says "NDA4024B 1" with "56J:" under it. It looks like it has a five speed tranny unless there is a high/low range lever somewhere. On the right side of lower engine it says "B9NN 6015B". Any help identifying model, hp, engine size, tranny info, pto info, year manufactured, or other related info would be greatly appreciated.

I would say you have a Mid to Late year 1960 Ford tractor . If the tractor was a 1959 the hood decal would read 871 or 881 not 801 as 1960 tractors do . The casting number B9NN-6015-B is a 1960 casting number only except for late 1959 tractors or early 1961 tractors with leftover production engines in them . There are lots of S-O-S tractors around that have been changed over to 4-speeds or 5-speeds , I have done lots myself for customers or supplied transmissions for them so that is very common. The NDA4024 casting number on the trans. with the date code 56J indicates Sept. 6, 1955 transmission which you did find the serial number and model number . The tractor WILL HAVE THE DUAL CLUTCH in it because there is no other way to use that transmission without using the dual clutch because it has TWO INPUT SHAFTS, REQUIRING THE USE OF BOTH CLUTCH DISCS . The rear axle housing casting number should read CONN-4024-B and should be on the left side just below the PTO cover , if it is different they may have used the early 1955 860 rear end also , The lift cover should have a casting number of NCA-501-B on it under the seat. Thanks Tony Jacobs

Tony, I'll bet you get a kick out of sitting back watching the rest of us scratch our heads, guess, theorize before swooping with ALL the right answers. Nothing like several years of "been there, done that". Thanks for hanging around and keeping us straight when we get too far off base!

Hi Jim, If I was not so damn busy I could check more often but of course that does not pay the bills so I try to catch up a day or so late. That's exactly what it takes is the years of work to know some of this stuff because Ford does not have all of it in print , Unfortunately . Thanks for the nice comments and I do plan on being here for a while . Thanks Tony Jacobs

Thanks for all the help. With closer inspection I found the serial number. It is stamped with "860" and "53674" with diamonds before and after. So am I assuming correctly that I don't have the correct hood on my tractor where it says 801 select o speed? And is this a good thing? Is the 860 with a five speed a good tractor? What does live pto mean? Any comments are greatly appreciated!

hi disqo,
If you're a cautious gambler, go with the odds. The odds are the hood and rear-end are original and the transmission's been swapped. Ask five people how to fix a broken Select-O-Speed and the odds are all five will say 'most people swap for a five-speed'. The model #860 and serial #53674 are normally the only numbers needed for identification and parts, but they're only found on the transmission. If the trans has been swapped, the other numbers you posted become more important.

You still don't know if it started out as an 860 and got a hood transplant, or if it started out as an 801 s-o-s and got a transmission transplant. What you do know for certain is that the transmission (at least) is a 1955 model. Do more looking. Check for date codes on the rear axle trumpets. Write down what you find and post it here. Also, clean the dust off the top of the radiator and see if there is a date code there. If both date codes come up 1955 we can be a little more sure that it started out as a '55 860. If the dates come up '59 or later then it looks like an s-o-s with a '55 transmission. If that's the case you may or may not have live pto. It will depend on whether a dual clutch was installed with the 860 transmission. To test, hook up a pto implement (mower, etc). Start the beast up with the pto engaged. Now push the clutch halfway down. If the engine becomes disengaged from the rear wheels and the pto keeps spinning then you have live pto. Otherwise you have the equivalent of an 850 (5 speed trans, non-live pto). Have fun with it!

The 860s are sought after. If it was a selectospeed and all thats long gone I would finish the conversion to an 860. The selectospeed had independent pto(ran sperate by hydraulics) and the 860 had live pto(ran off a dual clutch by pushing clutch pedal halfway). Your hood would still say 800 Diesel because that is the series and 860 would be the model. The hood and trans are two different year ranges the trans with the 860 would be 1955-1957? and the hood with the 801 series would be 1957-1962?

Hey DISQO, I will offer a couple of different possibilities. If you are correct about the 5 speed, you may have a 850/860 or a 851/861 with the wrong decal on the hood. If the decal is wrong, you may even have a 6xx series tractor. You need the serial number; the resource page will show you were to locate this. Tony, or someone else familiar with casting codes, may be some help.

I take it you read "801 select o speed diesel" off the hood. That would be the 801 series with a break down of models in that(840,860,etc) then selectospeed would be like a manual shifting automatic with I believe 10 forward 2 reverse, then of course the diesel engine. If you have the five speed then it was changed some time during its life probably because of the problems with the select o speed. Unless somebody took the trouble to find a trans out of an 860 you probably lost live pto because the SOS had independent pto driven by hydraulic that I dont know if it could have been retained in the swap, might ask Tony Jacobs. If you look on the trans boss right behind the starter you should find the serial number and model of the tractor which your trans came from, hopefully 860, but I think some manual changes were factory so I dont know what would be there.

Here is a place to get much more information on your tractor: >Link
Vintage>Link Ford Tractors

The Ford 801 Powermaster Series designation indicates a 172 cid engine built between 1957 & 1962, there were 24 models. The SOS transmission was introduced in 1959 so your tractor is a 1959 or later model. You will need the serial number located on the flat surface above and to the rear of the starter on the left side to tell which year. The number is hand stamped and is often hard to see due to dirt and excessive paint or because leaking battery acid has obliterated it. The Vintage Ford Tractor site above has a good description of the SOS transmission with a diagram showing its function. I don't know much about it as I have an 850 and 641 with standard transmissions. I am sure others will answer all your questions. Good Luck and have fun. Don
