HISTORICAL NOTE:

Caterpillar first introduced the RD4 in 1936 as the diesel version of the successful CAT 30 gas model. During WWII, the D4 was one of several tractor/bulldozers acquired by the military and simply designated as "Tractor, Light." The Ordnance Department assigned the designation “G-151” to the Caterpillar D-4 crawlers.

D4s served as prime movers for light artillery, general duty tractors and as bulldozers when equipped with suitable blade attachments.
