The 166-net-horsepower, Tier 4 Final Cat D6N offers three implement response levels – fine, medium, and coarse – and a single tiller control on the left armrest for direction, forward/reverse shifts and gear selection. The Komatsu D155AXi-8 has a 354 horsepower engine and lock-up torque converter. Its SIGMADOZER blade dozes up to 15 percent more soil than conventional blades, according to the company. The Komatsu intelligent Machine Control system keeps every- thing working together to maximize production. 2050M engines are built by Fiat Powertrain Technologies and use selective catalytic reduction, or SCR. SCR is well-suited for doz- ers, Bauer says. "It lets the engine run at peak performance under variable loads, without compro- mising power or drawbar pull. SCR also simplifies maintenance, as there's no regeneration and no DPF to maintain, and also improves fuel efficiency. Some models return fuel savings of up to 14 percent," he says. On the other hand, the Case 750M is designed primarily for the rental market, and its emis- sions system uses cooled exhaust gas recirculation and a diesel particulate filter. This requires maintenance of the DPF, but does not require refilling of the diesel exhaust fluid reservoir, which may be overlooked by rental customers, says Bauer. Other technological advances cited by Bauer include pressur- ized, isolated cabs that reduce dust and noise; expansive glass areas and cab-forward design that provide maximum visibility and direct line of sight to the blade edge and ahead of the dozer; and swing-out panels with pressure-closing latches for im- proved service access.
