Komatsu dozer and grader above 200 hp specifications

Choose the blade and ripper before comparing large dozers

The D475A-5E0 illustrates why a power-ranked list cannot identify a complete working arrangement. Komatsu’s CEN00075-04 brochure offers a Semi-U blade and a larger U blade, while dual tilt remains an option. The dual-tilt arrangement lets the operator change the blade’s cutting attitude during the pass.

A photograph showing that equipment does not establish what is fitted to another advertised D475.

Ripping equipment also changes the comparison. The giant single-shank arrangement uses a hydraulically operated pin puller and four depth positions. The multi-shank alternative has three shanks and two depth positions.

Identify the fitted beam, shanks and adjustment mechanism. The same engine rating can accompany either ripper, yet the equipment and intended ripping task differ.

Optional track-shoe slip control regulates engine output during ripping. It is a separate installation from the hydraulic pin puller or a dual-tilt blade. Include the controls in an equipment inspection instead of inferring that package from the large ripper visible behind the tractor.

The European D475A-5 equipment sheet makes a separate distinction: its standard heavy-duty single-grouser shoes are 710 mm wide, while 810 mm and 910 mm shoes appear in the optional list. That sheet also lists track-shoe slip control as an option. A wide-shoe machine and a machine equipped with slip control are therefore separate descriptions.

Check both against the actual undercarriage and controls before using another D475’s ground-pressure or equipment listing.

Quick-charge equipment has its own entries. The European list gives a provision for rapid fuel filling as standard, while oil-and-coolant quick-charge provision appears under options. Inspect the actual connections when planning service access; a fuel-filling fitting does not establish the presence of the other arrangement.

Earlier directory inventory with unverified power figures; reference history
Earlier inventory statement20 crawler dozer pages: engine power from 205 hp on the D65PX-15 to 4,070 hp (unverified earlier power entry) on the D21P-6, and the heaviest single listing is the D575A-2 at 284,837 lb. 1 motor grader page: engine power from 280 hp on the GD825A-2 to 280 hp on the GD825A-2, and the heaviest single listing is the GD825A-2 at 58,092 lb. Half of the 57 Komatsu dozer and grader above 200 hp models sit between 240 and 525 hp, and half of the listed weights on single-model pages fall between 58,092 lb and 238,276 lb. The three most powerful are the D21P-6 at 4,070 hp (unverified earlier power entry), D475A-1 at 2,682 hp (unverified earlier power entry), and D65PX-12E at 2,615 hp (unverified earlier power entry). 16 of the 21 pages cover more than one version, and the D275A-2 to D375A-2 has the most, at 6.

Source ledger: interpreting model evidence

The D21P-6 belongs to the small-dozer comparison

Komatsu’s original operation manual gives the D21P-6 a flywheel rating of 39.5 HP at 2450 rpm. The separate D21P-6B entry is 44.4 HP. The catalogue entry of 4,070 hp conflicts with that documented engine output. It cannot establish the upper end of a working horsepower range.
