The Caterpillar D6N LGP is a low ground pressure crawler dozer designed for grading, dozing, and site preparation on soft or sensitive terrain. Part of Caterpillar's D6N series, the LGP configuration uses wider tracks to reduce ground pressure and improve flotation in mud, sand, wetlands, and other low-bearing conditions. It is commonly used in construction, land clearing, road building, and utility work. The D6N LGP combines a compact dozer frame with hydrostatic or power shift drivetrain options depending on configuration, along with blade and undercarriage setups suited to finish grading and general earthmoving applications.
