Komatsu offered CONEXPO-CON/AGG 2026 show attendees an exclusive preview of two next-generation crawler dozers

The dozers are engineered to advance productivity and efficiency in earthmoving applications from site development and road construction to mining. The D61PXi-25 dozer with intelligent machine control (IMC 3.0) and the D175AX-10 large production dozer represent the next phase in Komatsu’s evolution of powertrain performance, operator-centered design and integrated technology.

From precision grading to large-scale earthmoving and haul road maintenance, contractors are navigating tighter margins, skilled labor shortages and increasing pressure to move material efficiently. The D61PXi-25 and D175AX-10 are engineered to address these demands and to deliver measurable gains in productivity, fuel efficiency and controllability.

D61PXi-25: IMC 3.0 in the midsize class

The D61PXi-25 is a fully redesigned IMC dozer built to deliver force, precision and efficiency in a size class widely in demand throughout North America. Compared to the D61PXi-24, it offers up to 10% greater productivity and up to 10% greater fuel efficiency, along with an 18% increase in blade capacity and up to 20% more steering power.

Key features include:

IMC 3.0 with new 10-inch intelligent control touchscreen and updated user interface
Auto steering designed to support consistent operation and reduce operator effort
IMC operation helps maintain functionality if the GNSS signal is temporarily lost
Redesigned cab — enhanced visibility, ergonomic joysticks and centralized controls

With an advanced electronically controlled high-pressure supply and EGR-less engine design, the D61PXi-25 is engineered to help increase material moved per gallon while supporting precise grading performance. The new cab environment is designed to help operators maintain focus and comfort through long shifts, with enhanced visibility and customizable control settings.

D175AX-10: Next-generation performance in the large dozer class

The D175AX-10 represents the first of Komatsu’s next-generation -10 large production dozers. As the successor to the D155AX-8, it introduces a new main frame, track frames, powertrain, cab and blade system — all designed to help deliver high production and control total cost of ownership in demanding applications.

Compared to the D155AX-8, the D175AX-10 provides up to:

26% more horsepower, with 450 HP (336 kW)
25% increase in cubic yards of material moved per hour
15% enhancement in fuel efficiency (measured in cubic yards moved per gallon of fuel consumed)
35% tighter turning radius

This new dozer also features a new 4-speed automatic transmission and a redesigned semi-U blade designed for enhanced penetration and reduced material resistance. The next-generation cab delivers comfort and efficiency with exceptional ride comfort, KomVision 360° visibility system and user-friendly touchscreen monitor.

More power. Less fuel.

The D175AX-10 also features Komatsu’s newest offroad engine, the DBA127 EGR-less engine. This engine helps produce more power for stronger penetration and is designed to lower TCO by being more fuel-efficient and extending service intervals (reducing downtime).

“The contractors and mining operations we work with are asking for measurable performance gains without sacrificing operator comfort or long-term durability,” said Paul Moore, Vice President for Products, Marketing and Service.

“With the D61PXi-25 and the D175AX-10, we focused on integrating higher output, more efficient powertrains and advanced control systems that help move more material per pass while supporting operators in the cab.”

Integrated Digital Solutions and Lifecycle Support

Both models are designed to integrate with Komatsu’s broader digital and lifecycle support solutions. The D61PXi-25 incorporates IMC 3.0 technology, and both dozers are supported by Smart Construction solutions, Komatsu Care programs, Komatsu Genuine Parts and other service offerings designed to optimize uptime and long-term value. The D175AX-10 is currently targeted for introduction in North America in 2026. The D61PXi-25 is planned for a later launch timeframe. Timing and availability are subject to change and will be fully announced at a later date.
