Caterpillar introduced the first Caterpillar D3 and D3 LGP in 1972, It was manufactured in Japan only and powered by a Caterpillar 3204 Engine producing 62hp. It started a serie which lead from D3B, D3B LGP, D3C, D3C (LGP) series II, D3C (LGP) series III, D3C XL series II, D3G XL (LGP) Tier2, D3K XL, D3K LGP, to todays latest Caterpillar D3K2 XL (LGP) in 2012.

The D3K2 XL (LGP) belongs to the Small Dozers programm and has a Caterpillar C4.4 ACERT™ Engine producing 92hp, weights 18761 lb and has Blade width of 109.5 in - 124.0 in. and a maximum Travel speed - forward of 5.6mph.

As far my knowledge there have been, until today, no scale models under license from Caterpillar released of the D3 series Track-Type Tractor. Ad Gevers custom built a "one of a kind" Caterpillar D3C Crawler Tractor SA in 1:50th scale.
