ECMV (Electronic Controlled Modulation) Valve Controlled transmission automatically adjusts ease clutch engagement depending on travel conditions such as speed, revolution and shifting pattern. This provides shockless smooth clutch engagement, improved component reliability, expansion of component life and operator comfort.
ECMV sensors monitor machine operating conditions and electronically controls steering clutches and brakes depending on type of job, such as size of load during dozing, incline angle of slope or load. This provides smooth and ease of operation by reducing counter-steering going downhill.
PCCS lever, joystick-controlled, wet multiple-disc steering clutches are spring-loaded and hydraulically released. Wet, multiple-disc, pedal/lever-controlled steering brakes are spring-actuated, and hydraulically released, and require no adjustment. Steering clutches and brakes are interconnected for easy, responsive steering.
Undercarriage
The REU (Resilient Equalized Undercarriage) system provides very powerful traction, component durability and operator comfort. Outstanding traction can be achieved because the shoes always follow the contour of the ground. The X-shaped bogie-structured resilient equalized undercarriage performs independent see-saw motions.
To decrease vibration and shock, rubber shock absorbers are mounted on the X-shape bogies. The bogies and the rubber cushions provide different absorption characteristics depending on the ground surface.
When the machine travels on flat ground, the REU functions as a conventional rigid undercarriage. Whilst when the machine travels on uneven ground the REU maximizes the suspension effect to the best working advantage that can be offered.

- Operating WeightTractor weight 252,600 lb / 114580 kg including rated capacity of lubricant, coolant, full fuel tank, operator, and standard equipment.Operating weight 336,420 lb / 152600 kg including Super Dozer blade, counterweight, steel cab, ROPS, operator, standard equipment, rated capacity of lubricant, coolant, and full fuel tank. Ground Pressure 23.PSIDrivers point of viewOperator Comfort in this super dozer is paramount for safe and productive work and a quiet, comfortable environment is offered so the operator can concentrate on the work at hand. The large tinted glass windows provide as good a view as any dozer of this type if not better, and air filtration and a higher internal pressurized cabin prevent dust from getting in.
The operators seat uses a new suspension system with strengthened seams and a breathable fabric, fore and aft sliding rails and suspension springs are new designs to the D575A-3SD and increase strength and rigidity and reduce play and wear of the joints. This new seats is designed to accommodate all operators for support, ride comfort and fit.
For the Industries that employ these super Dozers, they are worth their weight in gold. They have the ability to work and work hard 24/7, and the technology of today, ever increasing and improving, results in reliable mechanics that keep these super Dozers often exceeding more than the job requires.As a researcher into these gi-normouse machines I never cease to be amazed at the raw power the Komatsu 575A-3SD with excellent traction, excellent engine and excellent hydraulics can deliver.It really is a case of any job...anywhere...any time, no worries...no problem......The Komatsu 575A-3SD, The Ultimate king of the hill, then it levels it ! and time for a coffee.
