How many air cooled tractors were made, and/or sold here in the USA? I am talking about full size and not lawn tractors. I seem to remember that Deutz or Porsche sold tractors here, air cooled, that may even have been diesels. Thanks.

Several years ago, we rented a Deutz-Allis air-cooled diesel, during planting season, when our AC 200 broke down. We pulled a JD 8-row planter, with the 200, and the D-A had about 20 less horsepower than the 200, but it pulled that planter like it was nothing (It did have FWA). Also used about 1/2 the fuel that the 200 does.

I have one in a Baker Forklift, 4 cyl., bought new in about 1984, always has ran great, even in these 100 plus degree summers, just keep the meeces out of the fins.

The Diamond Reo truck company, located in PA, put Deutz air cooled engines in their vocational models in the 80's. I think they had to stop due to the engines not meeting the pollution control regs.

Grandad restored an air cooled 4 cylinder out of a Case combine.
It wasn't factory, but I talked to a guy who retrofitted a Wisconsin 4 into an Allis B, as I recal he said it was a little light in the nose without the weight if the water

We ran a Deutz air-cooled V-8 diesel engine for several years in a large Liebherr track type excavator, (2-1/2 yd bucket), and it was very good, very fuel efficent, and very strong engine. It was oil cooled, with 2 large oil coolers that served as radiators, one for each bank of cylinders, and about 10 gals. of engine oil. Oil coolers are definitely the key to cooling these engines. The higher operating temperature of the air cooled engine's cylinder, along with the turbo charger burned the fuel very completely and very cleanly, as long as the coolers were kept cleaned off it was good, when they clogged, the engine would sieze the piston to the cylinder jugs.We finally had to change it out and replaced it with a Detroit, which was water cooled, but not as good at fuel economy and less h.p. per c.i.d. We never could depend on a parts supply the last dealear kept it for about 6 years,and we finally just left it with him and never heard any more from him, that was in '74! Gene Davis

How can air cooling keep a diesel cool enough? It seems to me like they make a lot of heat. Does make sense though, being that you don't have to deal with any liquid cooling system.

Duetz and Duetz-Allis had all their tractors air cooled, as well as the Gleaner combines during the merger. From what I hear they run well.

Johnny, have you ever seen a Wisconsin air-cooled v4 (or 2) cylinder engine? They are air cooled gas engines, ran all kinds of swathers & balers in their day, got up to 35 hp or so on some models I think?

Anyhow, lots of deep fins on the jugs, and shrouded tin controling the airflow from the fan controls the temp pretty well.

Remember, many tanks such as the M60 and m48 had air cooled Continental diesels which worked well. It can and has been done. Also, remember that diesels at low load or idle are internally air cooled in that their air/fuel ratios go way, way lean. Very different than gas engines. This is why they "slobber" after they've been idled any length of time.

The smaller Russian tractors Belarus were air cooled.

Last summer I found an air cooled Renault N70 diesel in a bone yard about 60 miles north of me. Not sure if they were ever sold in this country. That one may have found its way here from Quebec considering my proximity to La Belle Province.

I dunno how many were sold here. Deutz bought Allis in the 80's I guess it was and sold them about about 10 years later to Agco. They marketed Deutz air cooled diesels here while they were associated with Allis.

As far as I know they worked okay but they were a little too different and they never caught on. That's not to say that they weren't good tractors.

Air/oil cooled engines are a great design!! Think about all the parts they don't have to give you problems later!! NO radiator, thermostat, hoses, water pump, cyclinder liner crosion, and many more advantages! Deutz was selling tractors here in the U.S. in the 60's LONG before they bought Allis. They are very good tractors for their time, and hundreds were sold in my area, many farmers here are still farming with Deutz tractors. I've had (3) Deutz, and still have one. My (2) Agco's are all so air/oil cooled, and they are great tractors that start easily no matter how cold it gets (with out ether), warm up fast, and work all day with out complaint! There were many different brands of Air/oil cooled tractors imported into the U.S., and still are, includeing the one in the picture! Robert

Great photo work-especially getting your dog on the tractor! Which tractor is that-the AGCO?

Hi Terry, Glad you liked the picture. Yes, the tractor in the picture is an Agco Allis 5660. This is the bigger one of the two i now own. My dog "lives" to ride on a tractor, or any thing else that moves. He goes with my dad every morning on the 4wheeler when dad goes to check his trap line and do some other chores. Then he's ready to spend the rest of his day following me around, hopeing for more rides. :) Robert

I just remember when the air cooled Deutz engine hit the market here in the 70s, there was even an article in a farm magazine about retrofitting them into farm pickups. I met one guy that did it, he liked it, power was down, but mileage was way up. On air cooled engines, they do have a thermostat, on the cooling fan, and they have to have a very large cooling fan to push air past the clinders, and in an ag environment it has to be filtered, so the cylinder cooling area doesn't fill with trash and dust.

John, None of my air/oil cooled tractors have a thermostat on the fan, but i do now remember seeing some big Deutz engines with them. The only filtering the air gets, is from a screen in front of the fan, and it has fairly large holes in it. The cyclinder fins are quite far apart, and all the smaller trash is blown right on through. At least on all i've seen. I've NEVER had an air/oil cooled engine plug from trash, and over heat. BUT, i do from time to time check for trash. Robert
