Komatsu's D61PXi-25: IMC 3.0 Comes to the Mid-Size Dozer Class

Komatsu used ConExpo-Con/AGG 2026 to preview two next-generation dozers at once, and while the D175AX-10 grabbed most of the headlines for its 26% horsepower jump, the other machine on that stage deserves its own look. The D61PXi-25 is coming to replace the D61PXi-24 in Komatsu's mid-size intelligent dozer line, and it's bringing Komatsu's newest machine control generation down into a size class that a lot more grading contractors can actually afford to own.

What Komatsu Has Confirmed So Far

Komatsu is being more conservative with the D61PXi-25's numbers than it was with the D175AX-10, since the D61 is targeted for a later North American launch window. What the company has confirmed: an EGR-less, electronically controlled high-pressure engine, an 18% increase in blade capacity over the outgoing D61PXi-24, up to 20% more steering power, a claimed 10% improvement in productivity and a 10% improvement in fuel efficiency, plus a redesigned cab with what Komatsu describes as enhanced visibility, ergonomic joysticks, and centralized controls. The headline technology addition is IMC 3.0 — Komatsu's intelligent Machine Control platform — running on a new 10-inch touchscreen in the cab.

The D61PXi-24 Baseline: What's Actually Being Replaced

The outgoing D61PXi-24 runs 168 net horsepower at 2,200 rpm, carries an operating weight of 43,167 lbs., and moves a 4.98 cubic yard blade. It already runs Komatsu's intelligent Machine Control 2.0 with GPS-guided semi-autonomous blade control, so this isn't a dozer going from dumb steel to smart steel — it's Komatsu's proven mid-size platform getting its second generation of intelligent control plus a meaningful jump in raw pushing capacity. Komatsu hasn't published an exact new blade capacity figure yet, but if the announced 18% increase holds through final production specs, that works out to roughly 5.9 cubic yards — our own calculation from the percentage Komatsu has released, not a confirmed factory number, so treat it as a reasonable estimate rather than a spec-sheet fact until Komatsu publishes the final figure.

Why IMC 3.0 Actually Matters on a Mid-Size Dozer

Intelligent Machine Control has been a large-dozer story for most of its life — flagship machines getting the first generation of any new grade-control platform while mid-size dozers wait a product cycle or two. Putting IMC 3.0 and a 10-inch touchscreen straight into the D61 class changes who can actually buy semi-autonomous grading capability. A 43,000-pound-class dozer is squarely in reach for a mid-size site development or grading subcontractor in a way that Komatsu's large-frame dozers, covered in our CAT D6 vs. Komatsu D65PX-18 mid-size dozer comparison, simply aren't for a smaller shop. If your crew has been quoting GPS grade-control jobs but subbing out the actual grading work because you don't own a machine that can run it, the D61PXi-25 is the kind of mid-size intelligent dozer that closes that gap.

The 20% steering power increase pairs with that story in a way that's easy to overlook. More steering power at the same operating weight means tighter, more responsive turns while carrying a full blade load — exactly the maneuverability a grading contractor needs on confined pad sites, detention pond shaping, or any job where you're threading the dozer between property lines instead of running long, open passes.

The EGR-less engine design is worth a beat of its own attention. Exhaust gas recirculation systems have been a maintenance headache on off-highway diesels for the better part of two decades — EGR coolers clog, EGR valves stick, and the whole system adds failure points that show up as unplanned downtime years into ownership. Komatsu has been moving its dozer lineup toward EGR-less architectures across recent generations specifically to cut that failure mode out of the maintenance schedule, and the D61PXi-25 carrying that architecture forward matters more to your total cost of ownership over a ten-year hold than almost any single spec on the sheet.

The redesigned cab — enhanced visibility, ergonomic joysticks, and centralized controls, per Komatsu's own description — also isn't just an operator-comfort footnote on a machine like this. A dozer operator running IMC grade control all day is watching a screen, working joysticks, and still needs sightlines to the blade edges and the immediate work area. Every improvement to that visibility envelope reduces the odds of clipping a stake, a curb, or worse, a person on a site — a real safety consideration on the increasingly tight infill and redevelopment sites where mid-size dozers spend most of their working hours.

Who This Class of Dozer Actually Fits

The D61 class sits squarely in site development and grading contractor territory — pad prep, building site rough grading, and detention/retention pond shaping. It also fits land-clearing and reclamation contractors who need real pushing power without the transport weight and permitting hassle of a large-frame dozer, and utility and right-of-way contractors grading pipeline or transmission corridors where a mid-size machine covers more ground per day than a compact dozer without the mobilization cost of Komatsu's larger frames. If your fleet already includes a mid-size Komatsu excavator like the ones in our CAT 320 vs. Komatsu PC210LC-11 comparison, adding a D61-class dozer on the same dealer network keeps parts and service under one roof.

There's also a workforce angle worth naming directly. Skilled dozer operators, especially ones who can run grade control confidently, are hard to find and harder to keep. A machine with a more comfortable cab, more predictable steering response, and an intelligent control system that catches operator error before it becomes a rework problem is a real retention tool — operators want to run the newer, better-equipped machine, and a contractor who can offer that has an edge in a tight labor market that no spec sheet captures directly but every fleet manager feels.

Renting a Grade-Control Dozer Doesn't Pencil Out

GPS grade-control dozers carry some of the steepest rental day rates in earthmoving specifically because the technology is expensive and the demand for it is high. If your crew is renting an IMC-equipped dozer even three or four times a year, you're already spending enough on rental fees to be building equity in a D61PXi-25 instead — and every rental dollar spent on someone else's machine builds nothing toward your own fleet.

BFC structures dozer financing differently than a traditional lender. We're not just processing a loan and disappearing for the next five-plus years while you wait to qualify for your next piece of equipment — we're a growth partner. That means we can help finance your next machine, whether it's a second dozer or the excavator that pairs with it on the next job, while the D61PXi-25 you bought today is still being paid down. A financed asset that's actively earning is worth more to your business than a rental receipt, every single time.

Financing the D61PXi-25

We finance Komatsu dozers new or used, with deposit terms scaled to your credit profile rather than a flat percentage — that can mean $0 down for well-qualified, excellent-credit buyers and 20-40% for newer or credit-building businesses. Because a dozer this size represents a meaningful capital purchase for most contractors, we also build in protection through GPS telematics tracking from day one — IMC 3.0's connected platform makes that easier than ever, and both your insurer and your loan terms benefit from having real location and utilization data on a financed machine.

Timing your purchase around this launch also matters practically. Komatsu confirmed the D175AX-10 is targeted for North American introduction in 2026, with the D61PXi-25 on "a later launch timeframe." That gap is useful information for anyone currently shopping a D61PXi-24 on the used market — pricing on outgoing-generation units typically softens once a replacement's launch date firms up, which can work in your favor if you're financing a used D61PXi-24 now while waiting to see the -25's confirmed specs and availability before committing to the newer platform.

Bottom Line

The D61PXi-25 is Komatsu pushing its newest machine control generation down into the size class where the most contractors actually operate. The blade capacity and steering power gains are real, the IMC 3.0 platform is a genuine step up from IMC 2.0, and the timing — slated behind the D175AX-10 for a later North American launch — gives you a window to plan the purchase instead of scrambling once it's on dealer lots.
