Hi I am just getting a 1970 Ford 4000 tractor which I believe has a gas engine. Any other info from these numbers that are still very clear on the foil tag under hood
Serial is C263287 model is D. 1424. CS. Wonder what this means? Engine is 9M31B. Any info would be greatly appreciated
 
C263287 is a 1970 serial number.

Model number D1424CS:
D14 at the beginning says that it is a 4000SU (SU means "Special Utility"). The 4000SU is also referred to as a 4140 in the parts book. The 4000SU had the 201 ci engine of a 4000 series and the double reduction rear axle with inboard wet brakes form the 4000 series, but it had the the radius rod front axle and double sided steering linkage like the 2000/3000 series.
The 2 means that is has a gasoline engine.
The second 4 says that it has independent 540 rpm PTO.
The C says that it has an 8 speed transmission.
I am not sure what the trailing "S" means.

Engine number 9M31B means that the engine was assembled on December 21 1969.
 
Thanks for the info. Are these gas engine easier to start in winter? I am new to this forum and farm tractor as well. I have always liked the look of these old Ford tractor. My friend is letting me have this one at very good price.
 
Those SUs are very good tractors with a
lot of power for their size.
A lot of guys here would like to have one.
They do have a girlie front end on them
compared to the regular 4000 so will Not
ever make a good loader tractor.
Diesel is more efficient, has more
longevity and is more reliable but the
gasser is not to be despised.
I have a 3 cyl diesel that is a little
smaller than yours. I put a block heater
in it. If I plug it in for an hour or two
it will start right up like it's July.
If you put a block heater on yours you
will have no problems starting it even on
below zero days.
Have fun with it and welcome to the forum.
 
i will post some pictures that i was sent, still looking for a ride for this tractor and brushhog from rochester IN area to north NJ

Good looking tractor!
Don't like having a loader on the smaller sweep back axle models but many have them and use them regularly.
I have both models, 4000AP and 4000SU.
4000SU is powerful but compact, good for working in confined spaces but powerful enough to do bigger jobs.
4000AP has been my work horse for many years, although I have larger tractors the 4000AP is still my main go to tractor.
 
(quoted from post at 23:20:13 01/20/19) 9M31B would be a New Year's Eve tractor, not a winter solstice tractor. :)

Bern, he said that 9M31B was the engine number, not the Unit number. Hard to tell from that small picture of the tag, but it looks like the unit number is 0C30B which would make it a March 30 1970 Day shift tractor.
 
i was able to work on the picture of the foil tag, i was not sure if you could zoom on this site when i first posted it, the numbers are very clear still on the tag.
 
What's the opinion of vertical muffer compared to this must have some exhaust pipe in nder tractor. Seems like it just get to be a problem under the tractor.

Depends on what you'll be using the tractor for. Only problem with a horizontal exhaust under the tractor really would be if you plan to mow a lot of tall dry brush where the hot muffler might set something on fire. Vertical muffler is a problem when working under tree branches, so it's a trade-off based on what you want to do.

That tractor has obviously had the horizontal exhaust its whole life, or at least the tractor that had that hood on it when it left the factory has. A vertical exhaust requires a hole in the top of the left side hood panel just forward of the air filter, and tractors that have been converted still have that hole, usually with a plug in it.
 

I'm not a big fan of horizontal exhaust because of hot lift arms and they blow to much dust up in my apps, but I have bent over a few mufflers and had limbs slap me in the face from vertical exhaust.

Tractors with factory vertical exhaust have a raised ridge around the hole where the muffler comes through to keep water from running down on the engine.
That tractor has a nice looking hood and I'd hate to see a hole cut in it for a vertical exhaust, if you decide to switch to vertical exhaust please replace the left hood panel with a correct one rather than just cutting a hole..

The exhaust is either in your face all the
time or in your face when you are hooking
up an implement.
I have been running horizontal for 15
years and never had a problem with it
except once I bent the muffler on a hidden
log that bounced up when I ran over it
bush hogging. In fact I converted mine as
a vertical pipe would get torn off in
short order by limbs, etc.
I wholeheartedly agree with Destroked
about not cutting a hole in the hood.
I looked for 2 1/2 years to find a nice no
hole left hood for my 3000 that wasnt
butchered or beat up.
 
What are the negotiates to a loader with this type tractor?
This will be my first farm tractor so I try to learn as much as I can
 
Please tell me some of the reasons why the loader might not be as good with the axle configuration. I like to learn as much as I can
 


The su has a ford 2000/3000 from end that is a bit lighter and rated around 2000 lbs. The pivot for this lighter axle will eventually wear out the bolster or front end casting that holds the pivot and then the axle. At a certain point, ford increase the diameter of the pivot, to help it carry the load better where front end loaders were used on the farm or ap model. They also made a derivative models /4 and /5s that had heavier designed front ends for utility and commercial tractor.
