Model history

Main article: International Harvester

For gasoline-powered model see International B414 gasoline

The British-built International B414 diesel utility tractor was introduced in 1961 as the replacement for the B275 (although the older model continued in production until 1968). The B414 used the same basic 4-cylinder diesel engine design but a ¼" larger bore increased engine displacement from 143 ci to 154 ci. A gasoline version was added in 1962, primarily for the US market. In mid-1964 the US-built 424 was introduced in the US as the replacement for the B414, but the older model continued in production until 1966.

Tractor Comparison, diesel models in US

In 1962 the International B414 diesel was lower-priced than all of its competitors except for the John Deere 1010. By 1966 International Harvester was promoting the US-built 424 in this hp class but the still-available B414 served as a price leader and undercut the price of the newer-design Ford 3000, John Deere 1020, and Massey Ferguson MF135 significantly and the Fiat-built Oliver 1250 by a small amount.

Manitoba, CanadaTractor data says it is a 414 but when searching in some other forums i have found a few posts that say it is a 436. Just wondering as i am looking at a 1066 that is supposed to have a 1086 engine transplanted into it and the more hp the better. TIA

southern saskatchewanThink the 1086 had a 414 with a turbo, the 986 had a 436 without the turbo, the 14 and 15 where a 436 with turbo.

NE IndianaThe 1066 also had the 414 turbo, same as in th1086.

sw MIThat's what I always was told.

Manitoba, CanadaOk. Most of the material i have read says 414 also. There is about 20 PTO hp difference between a 1066 and a 1086. Is the pump just turned up or are there other updates done to the engine as well? Also, are these engines strong performers or do they fall flat on their face when lugged down a bit?

NE IndianaHave owned a 966, 986, 1466, and 1586, they will pull like crazy even at low rpm.

North Liberty and South Bend, IndianaI don't know if I'd say they pull like crazy at low rpm's.

Texas/New Mexico StatelineOurs has a DT414.

Good pulling little engine. It will pull more than the 135 hp it is rated for.

NCent. they don't. They usually pull to a stop at low rpms. At least in my experience

NE IndianaOpinions vary but in 30 years of running them I will stick with my statement. And yes I have ran other colors with similar horsepower and always was impressed with the low rpm torque /hp of the IH engines.

I have three 1086's and they all have 414's. it should be stamped on the block, under the intake. The CID will be the first three numbers I think.

i believe changes were made to the engine in the 1066 in 74. Horsepower may depend on what year 1066 it is using for horsepower ratings.

Caraway, AR

Set the torque cam angle around 135* and back the droop screw out all the way and they will pull like a low rpm and at high rpm.

Need a good operator on it if it's going to run that way, though.


NW Central Ohio...really doesn't matter does it? If it's the DT414 like it should be, it will be a 130 HP class motor. If it's a DT will be a 130 HP motor...unless someone has messed with the pump. If you want more up the pump. If you need to rebuild...just put a DT466C short block in it...fits the same, probably can turn 180 PTO HP all day long if your radiator is good.

Manitoba, CanadaThanks for the responses. I think I will probably take a chance on it.
