XCMG D5AT Bulldozer

Powered by the SC9DF270G3 diesel — 199 kW (267 hp) at 2,200 rpm, EU Stage III emission. 68 kW more power than the D170 (131 kW WD10G178) at the same 17.4-ton operating weight. Higher power-to-weight ratio supports more aggressive push duty cycles than the D170 within the same chassis envelope. EU Stage III opens markets requiring tighter NOx and particulate limits.

Direct Stage III alternative to the D170 in the XCMG 17-ton crawler dozer class. Same 17.4-ton operating weight, same 2,800 mm minimum turning radius, similar ground pressure profile. Choose D5AT when emission jurisdiction requires Stage III; choose D170 when Stage II is accepted and the lower-power simpler-spec engine is the better fit.

Ground pressure 55/50/46 kPa across the three blade configurations supplied. Lower than the D170 (56/51/47 kPa) by 1 kPa per configuration — marginal difference from the slightly extended track footprint. Standard-track undercarriage suited to firm to medium ground; soft ground sites would call for the D170LGP wide-track variant.

Hydraulic drive with electronically controlled shift. Limit-load control protects the powertrain under heavy push loads. Intelligent control with hydraulic pilot blade — eases operator effort over long shifts. Construction data management onboard for fleet cost tracking. 5,580 × 3,455 × 3,300 mm overall dimensions — slightly more compact than the D170 (5,930 × 4,060 × 3,600 mm).

SC9DF270G3 engine cross-shares with the D260 (Stage III) and D260LGP (Stage III) variants in the XCMG export dozer line — single engine parts pool covers all three Stage III models. Blade edges, ripper teeth, undercarriage components, and hydraulic seals share core part numbers with the D170. Genuine XCMG parts available through me-equipment.com's authorized dealer channel.
