So far, the only model of a Komatsu D455A is this 1:50 scale offering by Diapet of Japan. It was issued not long after the real machine first went into service, and accordingly represents an early production machine. Attachments include an S-blade, single shank ripper, and the optional cast manganese extreme service track shoes. Bulldozer, Komatsu, Hitachi, Scale Models, Hyundai, Quad, Tractors

Image from a Komatsu brochure of the late 1970s sees an earlier D455A going about its business in some fairly hard going. The sheer weight and size of the D455A made the machine ideal for this sort of work. Earlier style cab and ROPS are noteworthy. Dozer, Cab, 1970s, Ideal, Activities, Machine, Weight

A very early production Komatsu D455A photographed in Germany shows a tired undercarriage and worn sprockets. Undercarriage replacement on one of these machines was a major job (not to mention expense). The D455A’s successor, the D475A-2, utilized a modular design making repair/replacement far less time and labour consuming.

The ‘Giant Ripper’, Komatsu’s term for the lethal looking single shank ripper fitted to the rear of this D455A and subsequent (D475 and D575) ‘Super Dozers’. Barely discernable in this photo is the escape hatch cut in the roof of the ROPS to allow the operator a hasty exit if necessary.

Nearing final assembly in Komatsu’s Brisbane, Australia branch is this Komatsu D455A-1. The ROPS over the cab has yet to be fitted but it does have its single-shank ripper installed. It was unknown when the author visited in 1982 what type of blade was to be fitted. Mining Equipment

Good rear end photo of a Komatsu D455A-1 with the later style cab and ROPS> Equipment includes the standard 15-foot wide S-blade and a pocket at the rear for a counterweight. It would appear that this particular example has never been fitted with a ripper even though the mountings are there and that the machine was most likely used for reclamation or stockpiling.

Komatsu’s first track type tractor was the model G25, introduced in 1931 and intended for agricultural work. It was a re-engineered copy of the American Holt 2-Ton, some examples of which had been shipped to Japan years earlier. Agriculture Tractor, Old Pictures, Military Vehicles, Monster Trucks
