Komatsu Redesigns D175AX-10 Dozer

North America – Komatsu Ltd., a leading Japanese Original Equipment Manufacturer (OEM) of construction and mining equipment, through its North American operations, has introduced the all-new D175AX-10 production dozer, designed to deliver higher productivity, improved fuel efficiency and reduced total cost of ownership. The completely redesigned machine is engineered for demanding applications, including mining, aggregates production, large-scale construction and infrastructure development.

Powered by a 450 HP (336 kW), 12.7-litre Komatsu DBA127 Tier 4 Final engine, the D175AX-10 features an advanced four-speed automatic transmission with 30 speed settings, a redesigned powertrain and an innovative hydrostatic steering system. Compared with its predecessor, the D155AX-8, the new dozer delivers up to 25% higher productivity, 15% better fuel efficiency and 27% greater engine horsepower. Its advanced steering technology provides up to 17% more steering force, while the redesigned 13.9 yd³ semi-U blade improves material retention, reduces digging resistance and enhances pushing performance.

The D175AX-10 also incorporates several operator-focused innovations, including the KomVision 360-degree camera system, an 8-inch touchscreen monitor, improved cabin visibility and enhanced machine controls. Its redesigned undercarriage and cab isolation system reduce vibration by up to 35%, supporting greater comfort during extended operations. Additionally, improved service accessibility, extended maintenance intervals and an EGR-less engine design contribute to potential lifetime maintenance cost savings of up to 28%.

With its combination of powerful performance, advanced technology and reduced operating costs, the Komatsu D175AX-10 represents a significant advancement in heavy-duty earthmoving machinery, reinforcing the company's commitment to improving productivity, reliability and operational efficiency across the global construction and mining equipment industry.
