The Caterpillar D6C is a crawler dozer produced by Caterpillar as part of the D6 series. Designed for earthmoving, grading, land clearing, and site preparation, the D6C uses a tracked undercarriage for traction and stability on soft or uneven ground. It is commonly equipped with a front blade for pushing and leveling material and may be fitted with a rear ripper for breaking compacted soil or rock. The D6C is recognized as a mid-size dozer used in construction, forestry, mining, and agricultural applications. Its mechanical design reflects the durability and serviceability associated with older Caterpillar crawler dozers.
