The International 8-16 Junior tractor was built from 1918 to 1922 in the International Harvester Tractor Works, Chicago, Illinois, USA. It was called the 8-16 or 8-16 Kerosene in the USA and called the Junior in England.

Model HistoryEdit

When it was introduced in 1918, the new International 8-16 was built in the style of International’s trucks of the day, with a sloping hood and the radiator behind the engine. The original VB-series had a 251 ci ohv 4-cylinder 3-main-bearing engine borrowed from the truck line and the tractor used a 3-speed transmission, like the smaller trucks.

In mid-1919 the upgraded Series HC International 8-16 had a redesigned engine with the three regular main bearings replaced by two roller bearings. The revised tractor also was given a water bath air cleaner.

The International 8-16 was revised again with a larger engine for 1921. The new Series IC had a ¼" larger bore for a displacement of 284 ci. When tested at Nebraska it developed 19 belt and 11 drawbar hp.

The price war with Ford lead to the 1921 price of $1150 being cut by February 1922 to $670, with a 2 furrow plow included.[1]

It is believed about 2,500 were imported into the UK.
