Komatsu D39EX-24 crawler dozer is a mid-size tracked bulldozer designed for grading, site preparation, road building, and general earthmoving. It is part of Komatsu's D39 series and uses a hydrostatic transmission for smooth, responsive control and efficient operation in confined or variable ground conditions. The D39EX-24 is commonly equipped with a six-way blade for dozing, leveling, backfilling, and finish grading. Its undercarriage provides traction and stability on soft or uneven terrain. The machine is used in construction, utility work, landscaping, and light-to-medium earthmoving applications where maneuverability, control, and reliable pushing performance are required.
