2 stroke diesel engines in tractors

It's been a while since a two stroke has been installed in a farm tractor. I would be more concerned about the reliability and cost of operating an old machine.
Is the tractor a collector's unit? An odd jobs tractor on a real farm? For use on a hobby farm? The prime tractor to make you living with?
The Deere 8010/8020, the 435, Cockshut 1950 and Oliver 99/Massey something clone are all that come to mind in North America. There is the German Lance. iirc there was Chamberlain or something two stroke in Australia ?
The Two stroke Detroit Diesel problems mostly stemmed from operators who did not understand it.
 
The Detroit in the Case LA is a real powerhouse I almost bought one but Mother said no. It would have been a pulling tractor that's for sure.
Lots of power and 2000 RPM for that grab on and ride it out.

I have three tractors with Detroit Diesel engines in them.An Oliver 1900 with a Detroit 4-53,Oliver Super 99GM with a Detroit 3-71,and a Case 900 that I installed a Detroit 4-71 in.They are wonderful.I have used them to plow with and the power is great.Fuel economy per hour used is unsurpassed.Open them up wide open in the gear you choose and leave it there and it is pure power.Back in the 40s and 50s Detroit made kits to install there engines in all brands and sizes of tractors.They were as reliable if not more so than any manufactures engines.
 
Occasionally see John Deere's such as 5020's advertised with (retro installed?) 2 stroke Detroit's/GM's in them and am curious as to whether who, if anyone, offered them as OEM power plants in their machines and how they compared in performance.

My first tractor was 1959 JD 435D with a 2-53 Detroit Diesel (#6 off the assembly line). The chasis was pretty well used but the engine was strong. It was hard starting in temps below 40F but it was a plenty powerful and very economical to operate for what I used it for (mowing, dragging a pasture harrow, and grading driveways, plowing snow, etc). Seems like I hardly ever put fuel in it. I had it for about 10 years and sold it for $1000 more than I paid for it.
 
My Grandfather bought a small Holder B10D tractor in 1956. This tractor is powered by a single cylinder, two stoke diesel engine with direct injection. Displacement 60 cubic inch and 10 hp at 2200 rpm. It has a dry sump lubrication; oil is injected and burnt in the engine.
The engine was designed the by German Holder company and built by Sachs.
This tractor has served us a recorded and documented 7000 hours without a lick of trouble.

The Detroits are relatively easy to get a lot more power out of by simple over the counter bolt-ons. Like much larger injectors.
 
Because two strokes fire every time the piston reaches TDC, as opposed to a four stroke that does everyother time, they produce more power, but burn more fuel. In theory twice as much of both, but in actuality they do not produce twice as much power. While two stroke diesels do not usually require mixing oil for lubrication, they do require inlet air be pushed into the cylinder, as any vacuum would be broken when the scavenging ports are uncovered. Blowers do this. Overall, 2 strokes aren"t a bad engine.
 
They must of done better in tractors then in Trucks ?
I was running a Mack that could idle into a mud hole no problem and the other guys had GM with screaming Detroits. Made alot of racket and hardly went anywhere. Same with an old service rig out by me you hear it coming miles away and it takes forever to get there and then forever to get out of ear shot.
 
GM sold many times more two stroke Detroits than Mack sold four stroke diesels.

They must have been doing something right.

Hi
As somebody said field marshal, Dad was talking about them at the supper table last night. He said unbelievable torque, just search Field marshal tractor pulling on tube will answer that, fuel economy about 5 gallons U.K to the day threshing. reliability, well some are way over 50 years old and beat to death but still run. Never been a fan of anything that had screaming or Detriot 2 stroke in the name , way to much noise for what comes out at the flywheel. like the straight 6/turbo of most brands or v8 diesels although they can be gutless wonders sometimes.
Regards Robert
 
Or not. Many old Macks are still on the job. They were a heavy duty unit for sure.
Gm out sells lots of makers,but I'm not a big fan of theirs anymore.
 
Enormous numbers of 2 stroke detroits are still on the job - many more than four stroke Macks.

Two stroke detroits were the best thing that ever happened until the 4 cylinder cummins came along. Since the Detroit only replaced a horse or two it didn't have a lot to live up to.
Short answer... they're the most gutless bloody thing you could ever hope to install in a tractor or industrial machine. If you're doing something that requires torque rise, the Detroit is not the ticket... otherwise their biggest accomplishment was the efficient ability to turn diesel fuel into smoke and noise.

different strokes for different folks :lol: Detroit's are out dated in a few ways for sure but if they were that bad they wouldn't have been in so many applications. and the military still uses v92 series engines. most people do not know how to run one to get the most out of them. We have five just in trucks alone. and properly adjusted they pass emissions just fine. Detroit got a bad rap in late 70's with the first 92 series [green one's] but the silver series was a very good engine.

I'd be interested in hearing more about the Case 900 with a 4-71. Any pictures?

What job are they on? It seems that I see about 10,000 Macks for every two stroke Detroit that I see.

10,000 Macks ........................How big are the fish you catch ?
 
Other than some pretty select applications... you don't find too many green demons around here any more. Specifically in truck applications you will find a LOT more 237 Mack's around than any similar generation Detroit...
Detroit's died a sound death here over 20 years ago.

About the only thing you need to know to run one is that you jamb the pedal to the floor and hold it there for dear life... Their inability to lug is quite detrimental in a lot of off road applications.

Ok, I'm about to show my stupidity, I've seen a bunch of those diesel engines like yawl are talking about and always called them a 2 cylinder diesel never realized nor was I ever told they were 2 stroke diesels, I will say one thing about those 2 stroke diesels that I remember, they were not the fastest thing on the earth but man could they ever work and pull. To me a diesel is made to work and pull especially a tractor or any other farm equipment and to the best of my memory those things could and still can move a mountain. I love reading these different post, I learn something every time I seat and start reading.

B&D, do you ever have anything good or kind or edifying or friendly to say? You obviously know a lot about many things and have a lot of life experience, but I expect that your home is a very dark place. I feel sorry for you! So about Macks try this: Go to Truck Paper and see how many trucks you can find that have Detroits in them. Not going to find many. Then look at Macks for sale, 99 out of a hundred have Mack engines. I used to see a fair amount of trucks with Detroits. My wife's step father had one, A place that I worked in the 70s had a bunch of them. But few are on the road to be seen any more. I drive a fair amount, and can easily see over 100 Macks on a given day. Here in the Northeast they are fairly popular, I drive one from time to time. Maybe you have a truck or something in your area that commonly uses Detroits, but in the North East I know of no common use for them. The only place that I know of to see any are at tractor pulls, where there used to be a few but for the last five years there is only one that is brought out. So I will stand by my 10,000 to 1 estimate and I don't know how big your fish are but I will say that I think that I can smell them rotting from here.
 
The Oliver 995 was the one tractor that had a Detroit with the right trans for it.By shifting automatically it let the engine keep its RPM up to speed and Detroits need to run about wide open to make HP.
 

Certainly struck a nerve calling you on the lack of basic math and exaggerating stories. So much so you had to revert to insulting the family.
Maybe all you see are Mack's because that is all you are looking for?
 
The "Standard of the World", in Railroad
Locomotive engines is the GM, Electro-Motive
Division, 16V645, a V16, 645 cubic inch per
cylinder, 2 cycle, 3000 horsepower engine.There
are thousands of them, all over the country
pulling trains everyday. The basic design,is from
1936, and is just a "Giant Detroit Diesel" It
uses about 40 gallons per hour idleing, at 200
RPM, and 200 gallons per hour pulling a train at
60 miles per hour at 800 engine Rpm.
The latest model is a 4000 horsepower 16V710, at
710 cubic inch per cylinder.
After they've sat in a terminal all weekend, and
start out on a Monday morning train, when you
open the throttle, it rains drops of oil for a minute or so...they do tend to "Drool" a little !
 
I take the tractor to a plowday every 2 or three years(Case 900)and pull either a 4-14 moline plow or a john deere 5-16 moldboard plow.The ground in that red river valley is red loam soil and very tight.I can pull those plows in third gear and fly.The tractor has awsome power.I have 18.4x34 tires on 20 inch rims to get all the tread on the ground.I pull it in the 10,500 lbs class and it holds its own pretty well.
