This black & white educational/promotional film is about the medium Caterpillar tractors D6, D7, and D8 models, most often configured as bulldozers (but also sold in other versions). This is circa 1946. The D6 was also available in a military version classified as the SNL G152. The D6 started out in 1935 as the RD6, fitted with a 3-cylinder 45 hp D6600 engine. The RD6 was renamed D6 in 1937, and updated in 1941 with a D4600 engine of 55 hp (drawbar) and in 1947, with a D318 engine of 66 hp. The D7 and D8 were first manufactured in 1938.
