Komatsu D51 Dozer

Although Komatsu's D51 crawler dozer replaces the D41, the D51EX-22 (standard) and D51PX-22 (low ground pressure) boast a ground-up redesign. According to the company, there are no aspects of the machine that were not improved upon from the D41. The new machine uses a dual mode hydrostatic transmission (choice of 3 or 20 speeds) and a 130-horsepower Komatsu Tier 3-certified engine. By moving the cooling package from under the hood to the rear of the machine, the company was able to steeply slope the hood, providing best-in-class blade visibility. In addition, the operator's station has been moved forward almost two feet closer to the blade. It also features a new track design and 10- or 11-foot, six-way power angle tilt blade with a capacity of 3.5 to 3.8 cubic yards. Estimated list price: $150,000–$220,000.
