The new D61PXi-25 and D175AX-10 promise higher productivity, improved fuel efficiency and new technology features
Komatsu delivered ConExpo attendees a sneak peek of two of its next-generation crawler dozers.
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-centric design and integrated technology.
From precision grading to large-scale earthmoving and haul road maintenance, contractors are navigating tighter margins, skilled labour 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.
“Both models have an all-new cab and operator controls, as well as increased production capability and more steering power for excellent manoeuvrability, which is very important on a dozer,” said Bruce Boebel, Komatsu North America’s Director, Products and Service – Construction.
D61PXi-25
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 per cent greater productivity and up to 10 per cent greater fuel efficiency, along with an 18 per cent increase in blade capacity and up to 20 per cent more steering power.
“The new D61PXi-25 is the first dozer in our lineup to get the enhanced features of IMC 3.0, which adds new dozer specific features to benefit customers,” Boebel said.
Alongside IMC 3.0, the dozer is equipped with a new 25-cm intelligent control touchscreen and updated user interface. To help simplify machine operation, Komatsu has developed a common user experience for both dozers and excavators equipped with IMC 3.0.

“Historically, they have been slightly different. We have made that common going forward to make it easier for operators moving between machines and to simplify training and onboarding for future operators,” said Jason Anetsberger, Komatsu North America’s Senior Director of Customer Solutions.
Another benefit of IMC operation is its ability to maintain functionality if the signal is temporarily lost.
“If you’re working under a bridge or alongside a building, it stays in automatics mode and continues grading even when we have a temporary loss of GPS or GNSS signals,” Anetsberger said.
The D61PXi-25 also features the first of its kind factory integrated auto steering, which is designed to support consistent operation and reduce operator effort.
With an advanced electronically controlled high-pressure supply and EGR-less engine design, the D61PXi-25 is engineered to help increase material moved per litre while supporting precise grading performance.
The new cab is designed to help operators maintain focus and comfort through long shifts, with enhanced visibility and customizable control settings.
D175AX-10
The D175AX-10 represents the first of Komatsu’s next-generation -10 large production dozers.
As the successor to the D155AX-8, the new dozer introduces a new main frame, powertrain, cab and blade system — all designed to help deliver high production and control total cost of ownership in demanding applications.
“The D175 also gets an eight-roller track frame for improved ride and comfort for the operator,” Boebel said.
Compared to the D155AX-8, the 450 hp D175AX-10 provides up to 26 per cent more horsepower and a 25 per cent increase in cubic yards of material moved per hour.
As well, the -10 machine delivers 15 per cent better fuel efficiency (measured in cubic yards moved per litre of fuel consumed) and a 35 per cent 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.
New cab
The next-generation cab delivers comfort and efficiency with exceptional ride comfort, KomVision 360-degree visibility system and user-friendly touchscreen monitor.
The new steering system enables pivot, power and spin turns without sacrificing blade load, enhancing manoeuvrability in side-cutting and scraper-push applications.
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 ownership cost by being more fuel-efficient and extending service intervals to reduce 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, Komatsu’s 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.”
The D175AX-10 is expected to be introduced in North America in 2026. The launch date for the D61PXi-25 is unknown.
