The CAT D6R XL Track Type Tractor bulldozer model measures 4" long from the back shank rippers to the front of the scoop. From track to track, the width is 1.5". There is articulation on the front arms and blade. THIS IS NOT A TOY. It is very small and fragile. It is made mainly for display purposes. This model comes in an individual window box. The Caterpillar D6 track-type tractor is a medium bulldozer manufactured by Caterpillar Inc. with a nominal operating weight of 18 short tons (16 t). The military versions were classified as the SNL G152 medium tractor, under the G-numbers classification system used for army tractors. The D6R replaced the D6H in 1996, and came in five models ranging from the 165 hp (123 kW) D6R to the 175 hp (130 kW) D6R XL and XR, and the 185 hp (138 kW) D6R XL (IG) and D6R LGP. All used the Cat 3306T 6-cylinder engine.
