I had the pleasure of working on a TD-6 was the tracked version of the Farm-all M & MD. The distributor is a really weird design and I swore to the owner that diesel engines do NOT have distributors! Built in the late 1940's and is still earning its keep 👍
I wouldn't say they are an improved version of the M, but a diesel version of the M. Both are very good. We have 2 of them and a Super MD. We would part with the regular MDs But I am in Alberta, Canada.
In about 1966 we had a 400 farmall for the main tractor and had a bearing go out in the rear end, the dealership came to pick it up and brought us a loaner, it was a 450 that started on gas and ran on diesel. I really liked that tractor and hated seeing it go when the 400 was fixed.
Nice video! Ive been around md's and wd-9's my whole life. Still got a wd-9 that i used to tractor pull with. Pulled it in 8500-9500lb classes. They have tremendous amount of low end torque. Fun tractors to tinker with
Duals were very popular in Ontario Canada IH M, MH 44 were 2 in my neighborhood. The first field I disked at 13 was on a tractor just like this one. Took me all day to do 30 acres in 3 gear LOL! but I was in heaven
> Took me all day to do 30 acres Did you know that an acre was once defined as the amount of land an ox could plow in one day? 30 times improvement here!
My dad talked about all the time 😊. Was this the only example of a tractor manufacturer that built a regular production engine to run on gas and diesel. ? I've never heard of another. They also had an earlier tractor, big 4 cylinder, lot more cubic inches that started on gas, and you switch over, not a row crop tractor. Does an expert here know if that was a similar head design to accomplish this. ?
IH built these "Gasoline Start Diesel" engines, in various forms from 1932 (T-40 Diesel crawler) to 1962 (early TD-15 crawler). The first IH diesel wheel tractor with this style of engine was the WD-40 introduced in 1935, the last was the IH 650 which was deleted in 1958
My dad's 1941 Farmall H had a small gasoline tank for warmup, then cut over to kerosene, which was cheaper back in the day. He bought it in the mid-1960's and never used it that way. It's still on the old farm but hasn't been run since he passed away six years ago.
That type of tractor engine was called a "Distillate" fuel engine. It produced less power than an equivalent gasoline fuelled Farmall H but was cheaper to run. In Britain it was known as "Tractor Vapourising Oil" (T.V.O.) and in Australia we called it "Power Kerosene".
They are a fairly reliable engine but have their quirks. The tractors having a gas and diesel setup is quite complicated. The cylinder heads are known for cracking.
Nice tractor! I collect antique tractors as well...l prefer the gas models over the old diesels because the gas tractors usually start up easily even in very cold temperatures here in Indiana.... I guess if you live down South that might not be an issue...
They did not have more hp than the gas engine. 1or 2 less actually. Less fuel use and cheaper at the time fuel. Info from Nebraska tractor tests. The super md had three more horse than the gas super M at 48 hp but the 400 diesel and the 450 diesel remained at 48 when the gas engines were higher at 50 hp and 55 hp .
That's correct. They were not any stronger for sure. I've had both. The Nebraska tractor test information says 36 hp for both. Then in about 48 they increased the compression and air flow on the gas M which put it at 38hp.
The only ones you got correct were 10 and 11. You've got to reconsider a lot of your list because you didn't consider the needs of other people who are in different situations than you.
This type of engine was unique to IH. The engine started on gasoline using spark plugs and when the engine was warmed up a lever was pulled. This shut down the ingnition system and startup carb. (right side of the engine. The engine was then supplied with straight diesel fuel from the injection pump and injectors on the left side of the engine. A smalll in the head close off and raised the compression to make it a true diesel. These type of engines were called "gasoline start diesels" IH mainly used them in their crawler tractors.
Yes it always was a diesel tractor. Tractor fuel was distillate. The distillate and kerosene tractors also gasoline start, but it was a regular carbureted engine and the tractor fuel goes through the carburetor. This is a true diesel engine but with a gasoline starting system. The intake manifold has 2 ports and is controlled by butterfly valves. One port is straight air and the other port goes through a small carburetor. There is no throttle on the carburetor, it is just there to give enough gas to idle and that's it. The Head has 3 valves per cylinder. Intake exhaust and starting. The starting valves don't reciprocate, they are held open, and what they do is enlarge the combustion chambers to lower the compression to around 5.5 to 1. When you put it on low compression it opens those 4 little valves and closes the butterfly valves in the straight air side of the intake manifold. This allows it to run on gasoline. You start it on gasoline and let it run a minute. This allows the cylinders to warm, when you switch it, the valves close and the compression is raised to 16:1. The butterfly valves open on the straight side and they close on the carburetor side. At the same time you switch the engine into diesel mode, you put the throttle in the idle position and the injection pump pumps diesel through the injectors and it runs like any other diesel engine. They are pre cup engines, not direct injection. But using half kerosene and gasoline would destroy the engine and the fuel system. The tractors that burned tractor fuel used the regular gasoline engine specially equipped. They had a starting tank like the diesel, but they had shutters and had to be running very warm before the tractor fuel would burn. They were equipped with a special manifold to help vaporize the fuel, and different pistons to lower the compression ratio.
Not quite, this had a carb and distributor along with some camshaft trickery to run the main (only) engine on gas to warm it up a bit before switching to diesel mode.
No the main engine can run on both gasoline and diesel. This is achieved by an extra valve per cylinder that enlarges the combustion chamber and a dual port intake that either sucks through a small carburetor, or goes directly from the air cleaner to the engine and the ports are open and closed by butterfly valves.

I love my "M". Use it everyday on the farm. A true workhorse.
Man this looks MEAN with the duals!!
Good way to tear the rear end up
How do you figure that?
We a super "M" narrow front with duals, it looked cool too
I think this one is just mainly for show... I agree you would do a number on the rear end if it was used for heavy work in this configuration..
Seriously. Where do you guys come up with running duals will tear up the rear end. That’s not how that works.
That thing’s a beast with duals on it 💪
Looks awesome. I just love these old tractors.
Dont get much nicer than that. Great vid.
Very nice looking & sounding old Farmall MD. Stay safe.

Smdta is top of the hill for that series. Really rare
That’s so cool I love the duals also 🇨🇦😀
My Wife’s Grandfather had one, heard all about it but I’ve never seen one, how cool!
What a mechanical marvel. Was that before glow plugs?
@@davekana8388 yep. The 60 series was the first with glow plugs.
Kyle Kenan I was sort of thinking that, thanks! Great machine!
@@davekana8388 it may have also been the only series other than the early 706s and 656s with the d282.
Such a Neat Underrated improved version of the M. I've been looking a few year up here in MI for one.

Back in the day we had a McCormic Deering WDR-6 that started on gas and you switched to diesel.

We had a M and MD on our farm..I liked the MD the best.. the diesel had a little more power.
I used one of those. A long time ago in a galaxy far far away. God, I miss my childhood. Schaghticoke Hill, N.Y. I grew weed in in 1972.

I love me some red tractors!
I love red power!! But i also love that music that was played in the video. Does anyone know the name of that song?
We have a 400 diesel similar to this, hasn't ran in years. Definitely not many around
I have a MD my self!back half 41, engine is mid fourties
Never seen an M with duals👍👍
I grew up on a SUPER M 💪 I raked more hay than I care to EVER see again 🤣🤣 nice , nice tractor

My Grandpa had an A and a G John Deere tractors that were dual fuel like this Farmall. He ran his on gas all the time.
@Hanson Farms Hanson, you just jogged my memory. My Grandpa's Johnny Pops were dual fuel. Kerosene was the alternate fuel. Thanks...
I would love to have a old MD
Also don’t these MD’s have spark plugs even though they run Diesel please correct me if I’m wrong
They do have spark plugs to run on gas. When the lever moves to switch to diesel it shuts off the carburator and the distributor.
It also closes a valve for each cylinder to bump up the compression and close off the spark plugs
Magneto, not distributor

I wonder if there's any difference in the reliability of the start on gas Motors as opposed to the Direct start diesel motors?
They are a fairly reliable engine but have their quirks. The tractors having a gas and diesel setup is quite complicated. The cylinder heads are known for cracking.
I know my MD has a compression release when switched to the gas side.It really helps with starting...
Biggest issue is being shutdown hot. They need to be left to cool of before shutting down, otherwise they are notorious for cracking heads.
Nice tractor! I collect antique tractors as well...l prefer the gas models over the old diesels because the gas tractors usually start up easily even in very cold temperatures here in Indiana.... I guess if you live down South that might not be an issue...
even when the primary fuel was kerosene, they were started using gasoline. Then, after warm-up, you toggled to the other tank.
Amazing #gmpunjabtractor

Starting on gas and switching to diesel and pony motors are one reason that I’m an Oliver fan and not IH, or Deere. Electric start for the win
If one ran out of diesel for some reason, could the tractor be operated as a gas-powered machine?
It just had a small carb with no throttle. Only ran one speed on gas, about 800 rpm. Could probably get you home but not much power.
Only have about a 1/2gal gasoline tank. Wouldn’t get far.
From what I have been told the gas m had more power then the md
That's correct. They were not any stronger for sure. I've had both. The Nebraska tractor test information says 36 hp for both. Then in about 48 they increased the compression and air flow on the gas M which put it at 38hp.

the truth is that little John Deere in the air cleaner is powering that Farmall
its a hybrid
Please put the right exhaust on it! It looks pathetic with the chrome stack!!
www.tractordata.com/farm-tractors/001/1/1/1113-farmall-md.html re horsepower
Standard system .. Nothing new
wrong on your hp
He guy really doesn’t know what he’s talking about
actually kerosene or coal oil
Wrong
Gasoline and diesel
No kerosene or coal oil or dandruff shampoo involved
This is an actually diesel engine which uses an injection system. The carbureted engines could be equipped to burn kerosene.
wtf why did you install a second set of back tires!??? its so ugly!
A pony engine start.nothing new.
Not quite, this had a carb and distributor along with some camshaft trickery to run the main (only) engine on gas to warm it up a bit before switching to diesel mode.
There is a valve in the head that opens up the combustion chamber to the spark plug. It also reduces the compression while open
Not a pony engine which cranks a main engine
Just a main engine that can achieve both spark and compression ignition
No the main engine can run on both gasoline and diesel. This is achieved by an extra valve per cylinder that enlarges the combustion chamber and a dual port intake that either sucks through a small carburetor, or goes directly from the air cleaner to the engine and the ports are open and closed by butterfly valves.
