What's New From Komatsu in 2026: The D61PXi-25 and D175AX-10 Dozer Updates

Komatsu used ConExpo-Con/Agg 2026 to preview two dozer updates that are genuinely worth a contractor's attention, not just incremental dash-number bumps. The D61PXi-25 and the D175AX-10 each replace a specific predecessor with real, measurable gains — and since we've already covered Komatsu's excavators and its previous-generation D61PX-24 dozer in depth, this roundup focuses on what's new since then.

D61PXi-25 Replaces the D61PXi-24

Komatsu's midsize intelligent Machine Control dozer moves from the D61PXi-24 — the machine we cover in our Komatsu D61PX-24 dozer financing guide — to the D61PXi-25, and the gains are concrete: up to 10 percent greater productivity and up to 10 percent better fuel efficiency, according to Komatsu's own testing. The new IMC 3.0 system adds a 10-inch touchscreen and auto-steering to the grading package, and Komatsu redesigned the cab around it. Blade capacity increased 18 percent and steering power is up 20 percent — the kind of change that shows up directly in how much material a dozer can push in a single pass and how tightly an operator can maneuver in a confined cut, rather than just looking good on a spec sheet.

D175AX-10 Replaces the D155AX-8

Komatsu's large production dozer sees an even bigger jump: the D175AX-10 replaces the D155AX-8 with 26 percent more horsepower, landing at 450 horsepower, paired with a 25 percent increase in material moved per hour. Fuel efficiency, measured in cubic yards moved per gallon, improved 15 percent — meaning the machine isn't just more powerful, it's genuinely more efficient at converting fuel into finished grading work. The D175AX-10 also gets a new 4-speed automatic transmission, a semi-U blade design, and a turning radius that's 35 percent tighter than its predecessor, plus a new EGR-less DBA127 engine platform. Komatsu is targeting a North America introduction for this model in 2026, which makes now the right time to start planning a financing timeline if this class of dozer is on your radar.

What This Means for Earthwork Contractors

Both updates point the same direction: more material moved per hour, better fuel economy per yard, and technology that reduces the skill gap between an experienced dozer operator and a newer one. For a contractor bidding earthwork by the cubic yard, a 25 percent jump in material-per-hour on the D175AX-10 directly changes what you can competitively bid on a tight schedule. If you're comparing Komatsu's dozer lineup against the competition, our Caterpillar vs. Komatsu excavator comparison and our Komatsu excavator financing guide cover the broader Komatsu earthmoving lineup.

Own It Instead of Renting It

A production dozer like the D175AX-10 is a serious investment, which makes the rent-vs-own math even more important to get right — renting a machine this size for anything beyond a short job adds up fast without ever building equity. Our rent vs. own comparison lays out the real numbers, and if you're upgrading from an older Komatsu dozer, our guide to selling your used equipment through BFC can help you get real value out of the trade.

BFC can help you finance either of these new Komatsu dozers and fund your next machine before this one's paid off. If you're buying before year-end, our Section 179 in 2026 guide shows how much you can deduct.

Financing It the Smart Way

Whatever's next on your fleet list, BFC finances the new Komatsu D61PXi-25 and D175AX-10 dozers the same way — structured around your cash flow, not a generic rate sheet. Because we're also in the business of buying and selling equipment ourselves, we know what these machines are actually worth used, which means straighter answers on trade-in value than you'll get from a lender who's never set foot on a jobsite.
