They are good honest work tools with a great lugging engine and make excellent blade, ripping, towing or push tractors.ДЄrpra Brazil make a nice model of the D8K in scale with an angle blade but it is a little hard to find and can be quite expensive. A list of New Zealand D8 owners would just about fill this magazine, and would include all major contacting companies past and present.

It was available in three versions - the 35A series torque converter drive, 36A direct drive and 46A series with powershift transmission. However several other improvements, notably to the operators area and the sheer size of the machine, were apparent. The horsepower increase was gained by turbo-charging, and Caterpillar subsequently tweaked this further, very early in the production run, to horsepower. The next major revision to the D8 design came in with the introduction of the horsepower model D8H. Attachment options were now all supplied by Caterpillar and the operating weight had risen to 20 tons. No other piece of Caterpillar mobile equipment used the D engine. Producing horsepower, the D diesel was a naturally aspirated six-cylinder inline engine that had been specifically designed for the new D8. Looking very much like its 2U predecessor apart from a larger fuel tank, the 13A series production run lasted from to and was not built in very large quantities.

This segment of the Caterpillar D8 story will deal only with the conventional drive tractors, that is, non hi-drive machines RD8 thru D8K.
