Air Cooled Diesel Engine

[WilliamBos]

Air cooled diesels are no more, due to emissions regs.

Deutz seem to have mastered them.

Did Kubota build them too??

I had a 120HP SAME Drago and a 60 HP SAME Solar The Drago was open station and the Solar had a cab The heat in the cab was electric,and had its own alternator.
The tractor ran on the cool side,running it hard I shot it with my infrared thermometer and the max temp on the engine on a 98deg day was 140 in the winter if I ran it with the vent closed I would have to push it hard to not make it smoke.
The tractors were not noisy as someone said in the previous post.
Fuel economy on both was excellent for those size tractors,The only negative was if you did not use the tractors all the time you have to check the air path and jugs for mice nest,I was made aware of this when I bought the first SAME if you don't you can over heat the jugs.I bought them both used and beat the snot out of them,No repairs were done on either just oil and filters.

Nice pictures!

I seen a picture of a Same tagged as an Oliver once. I know they built some retagged AGCO tractors as of late. I didn't relize they had built an air cooled though? I remeber seeing a few Deutz air cooled around in the seventies and early eighties. I never heard anything bad about them. They were easy on the fuel which was a plus then, as inflation was a serious problem then.

They were built into the early 2000's, Deutz Agrolux were air cooled. Also some Fendts (Europe) had Air cooled Deutz in them.

I never heard of Oliver using SAME, I know they used UTB that was a Romanian tractor sold as a 1250 Oliver 5040 Allis and 445 Long.
Some of the AGCO were SAME I don't remember the numbers that they were rebadged to.

Mouse nests were mentioned, but chaff or extreme dust can be a problem too. If you clog up part of a radiator then you reduce the system's cooling capacity overall, but if you get crud under the shroud and it covers part of the engine fins then you get a hot spot.

This issue cooked a Wisconsin engine (not diesel, but air cooled!) that belonged to my father in law, but I've run Deutz and Wisconsin engines in stationary applications without any problems.

@Redneck in training: The heated bed like in the Tatra trucks are done over here too. A friend worked in a mine in Alberta many years ago with a fleet of Euclid trucks that ran their exhaust through channels in the box; I doubt his workplace was the only one to do it. I think he called them smoke tubes.

There were a lot of Same's around here back in the day. I don't recall any being water cooled. From the Minitaurus 60 to the 160, all I recall were air cooled.

M60 tanks were air cooled V-12s and for the large size of their engines they only made 750 Hp. They also had short engine lives. M88 recovery vehicles still use a slightly more powerful version of the same engine. Very noisy.

Two of my three air-cooled tractors

Fendt 203P, 3 cyl Deutz of a little over 3 litres, 57 eng hp.

Deutz DX 3.70, 4 cyl Deutz of a little under 4L, 70 eng hp.

Both simple, reliable tractors - no cooling problems.

@ Psj12: Your mention of the M60 reminded me of Jay Leno's "Tank Car": Jay Leno's Garage: Now That's A Hot Rod - Popular Mechanics

I forgot to put in another thought about air cooled engines: They really need a cool-down period before shutting them off. It's a good idea with any engine that's running at peak output, but with air/oil cooled motors, it's more important.
