Great find. You know not too long ago my Granddad and I hauled home an early 1940 Farmall M with the same top cover as yours and it still has the correct seat. Thanks for listing all the other differences between early M and late M I find it quite interesting as I am currently rebuilding a 49 M. Another few differnces that I noticed on my granddads M is that the fill plug for the transmission oil has a raised boss around it elevating the fill plug. Also the early style belt pulley mounting flange has four bolts, instead of eight, also the later flange is thicker. Grandads M is serial number 8047 I do believe although I will have to check. It is neat to think that my M came out of the factory only a few hundred units behind yours. Im looking forward to the next installment and can’t wait to hear it run. As for the future of my Granddads M it has been pretty worked over and had a very hard life. Yours seems to be in way nicer shape. Good luck!
That’s cool that it’s so close in serial number there is several differences I missed or didn’t include if you read the parts manual they kept changing things until 42ish then they started changing again in 50/51 for the ramp up to the super M I wish I had my grandpas M it was like a 41/42 that I played on as a kid then it left before I was interested in them I’m glad you enjoyed the video and I will be getting to work on it soon
That’s cool I’m glad you liked the video stay tuned I’m going to start working on it soon at 22375 does it have any of the early features? I know it should have the later top plate
@Dr rust It does not have the top plate like yours. Does have the PTO like on yours. I have a original wide front end,but it is not original to the tractor. I can't remember my engine number,but it is not too far from the tractor number so I assume it's the original engine. All castings are J
Another interesting tidbit about M's... 1947 was the ONLY year that the hood decals said "McCormick Deering" above Farmall, AND had the new style IH logo. Early H's and M's are hard to find. Nice work!
@@DrRust For the most part they were. There is a reason why folks always say don't get the first year of car etc. I'm certain International Harvester put the real prototypes through all kinds of testing etc, but there is only so much you can learn in a lab. The general public will find the remaining shortcomings. I've helped work on a 68 Corvette (first year of the C3) which there are a ton of one off parts on that car for the same reason.
I subscribed. We just picked up a 1939 M this year. FBK4000 I did get it loose, but there's something else wrong. All the early Ms had magnetos, the 1939 and most of the 1940 models, the stop switch is mounted on the magneto, and is controlled by a cable. That was a nice find.
Did all of the 39s have the cable kill switch? I thought only the early ones did I’m super excited about mine and hopefully going to get to work on it soon Good luck with yours thanks for subscribing
Nice! Didn't know there were some many differences between 39s, early 40s and later 40s. I've owned a 1940 M Farmall for 30 years. I don't know the serial number right off the top of my head but it's probably a later one because it doesn't have the same features as your M. I know a farmer who owns a 39 M that his Grandpa bought new in 1939. I've never looked close enough at it to notice the differences. I liked the fact that it's been in the same family since 1939.
@DrRust It is cool. We have a D John Deere Grandpa bought new in 1925 and an Allis Chalmers WC Grandpa bought new in 1942. The D has always been on steel. The WC came into the Allis Chalmers dealer in town on steel wheels, war tractors didn't get rubber tires. Grandpa drove the 1938 WC Allis Chalmers flattop into town that he was trading in on the 42. The rubber tires were swapped onto the new tractor, and Grandpa drove home.
And the Allis story is cool I have a similar story about my great grandpa his rubber tires and electric start kit came in after the war was over for his 43 JD A and he had no idea it had been included with the cost of the tractor or had forgotten about it because he was very confused about what the dealer was talking about when they told him to come pick up the wood crates in 1945

@@DrRust thank your for giving me the link according to that my s/n 6877 39 h was about 740 from being a December 39 and about 3,776 from being a 1940.
I have sn 7897 but it has been assembled from several different tractors I belive the motor is out of a 45 or 47 the o and q look real similar and the front bolster is the later casting
i had a 50 m both the engine amd chassis serial number were the same. Now my 53 super h is off by a few hundred. From what i seen the regular H and M's matched.
They do not normally match I have 4 m’s and they are within a few I have one that’s within 10 but that’s about as close as they get normally there is some that the stars all aligned and they match but it’s very rare It’s also possible that a warranty replacement engine might have had the chassis serial stamped on it instead of the engine number since the warranty engine didn’t come off the same assembly lines but it’s definitely cool that you found one that matches
@@DrRust My super H doesn't match, But all my H's i currently own and have owned match. I know the power units must of made a difference but ive only owen 1 M It was a 1950.

You definitely bleed Farmall! You have a wide range of knowledge especially noting the mfr differences of parts and years. Great job.
Thanks I really tried to hard to put all that info in one spot and I still missed a few things

Sounds like you have a great tractor

I had one of these. Didn't know it was rare. 5th gear was slow , that's why I got rid of it.
Interesting I don’t think I’ve heard of a slow 5th gear set

Just resubscribed. somehow I became unsubcribed? one of our M's is a 39 serial number 4071
That’s pretty low I know a few people with 3 digit tractors but anything under 20,000 is hard to find
I’ve seen other people who got unsubscribed as well I have no idea what that’s about

Is it a Ih factory wide front or a aftermarket?
IH.
Might have to get them back together someday
All M's are just scrap iron.
Why do you say that?
The M was the worst mistake international ever made according to the engineers that developed it.
Where did you hear that?
From the engineers themselves.
Rubbish one of the best tractors ever built
