Case intends to adapt its hydrostatic 650L crawler dozer to residential and confined commercial work sites by retaining the power in a scaled-down package. At 74 horsepower, its Tier-3-certified Case engine is within one horse of the K Model, but the 17,550-pound LGP weighs nearly 2,000 pounds less. Overall height and length are both about 5 inches less than the K, and the standard blade is slightly smaller (4 inches narrower, and nearly 3 inches shorter). About 4 inches less track length on the ground makes turns easier.
Komatsu’s 264-horsepower D85-18 crawler dozer, aimed at large construction operations and small mining customers, features a Komatsu SAA6D125E-7 variable geometry, turbocharged and aftercooled Tier 4-Final-certified engine that the company says burns up to 5 percent less fuel.
The D155AXi-8 is another of the company’s intelligent machine control dozers that allows automated operation.
