Cat D4 with winch at Neath 2012 - IMG 7940

At Neath 2012

The Caterpillar D4 track-type series tractor is a small bulldozer manufactured by Caterpillar Inc.. It replaced the Caterpillar RD4 4G series.

HistoryEdit

Caterpillar first introduced the D4 in 1938 as the diesel follow on to the successful CAT 30 gas model.[1] In 1935 Caterpillar started the naming convention of 'D' for diesel or 'R' for regular gas followed by a number to indicate the relative size.[2] At the time of introduction the D4 engine produced about 40HP so the 4 indicated the relative engine power. The D4 series engines quickly increased in power so the numbers just became a figure of merit rather than indicating actual engine power.

Model rangeEdit

The D4 was built in many plants around the world.(I managed to find the following info regarding the serial no. prefixes for D4Ds, they surely did make them all over the place) [3]

Preservation examplesEdit

The D4 is a popular model for collectors as they were relatively common as a medium farm crawler tractor, and at about 5 tons, are reasonably transportable.
