Production
Built in Racine, Wisconsin, USA
The Massey-Harris 102 Junior was the distillate version of the 101 Junior. During early production years, the 102 Jr. had a larger engine than the 101 Jr. so they would have the same horsepower. A 102 gasoline tractor (102G) was a Massey 101 Jr. destined for the export market; the data and serial number would be the same for other 101 Jr tractors.
