History and use
This model is a 4U series manufactured in 1953. The D2 model was a diesel crawler tractor first manufactured in 1938. It was Caterpillar’s smallest diesel tractor. It was designed as a small economical tractor intended for farm work, and could pull 3 to 4 ploughs. It used a completely new engine and transmission. It was a reliable, low cost machine to operate and was versatile with applications ranging from farming, small landscaping contracts to surface coal mining. It had a Cat D3400, four cylinder, 3 3/4 x 5 inch bore and stroke diesel engine. The total number of D2s produced was 26,454
In 1947 the D2, 3J and 5J series, was upgraded to the 4U and 5U series. They were the same overall design but had a more powerful engine and significantly redesigned radiator housing, plus the addition of a dip-stick for the oil level in the gear box.
The model D2, 3J and 5J series were manufactured from 1938 to 1947. The 4U and 5U series were produced from 1947 to 1957. The 3J had a standard 40inch wide track gauge and the 5J had a 50inch wide track gauge. The original price was US$1,400
