Iron Profile: Cat^® D10N Dozer

First released in 1987, the Cat^® D10N Dozer is 6% heavier and 13% more powerful than its predecessor, the Cat^® D9L. To enhance stability and traction, Caterpillar^® introduced a 13‑inch longer extended track frame, allowing the machine to better harness its increased power for higher production in both dozing and ripping applications.

Most of the lengthened track frame is positioned toward the rear of the machine, which helps reduce front‑end rise while increasing the force applied to the ripper shank and improving dozer penetration speed. The longer track footprint also lowers rolling resistance, reduces compaction, and minimizes track slip by preventing the machine from sinking as deeply. Despite the dozers weight advantage, its ground contact area with standard track shoes allows it to exert 2.8% less ground pressure than the Cat^® D9L.

Total operating weight on the Cat^® D10N increased from 114,825 lbs. on the Cat^® D9L to 122,072 lbs. Flywheel horsepower from the Cat^® 3412 diesel engine was also increased, rising from 460 HP to 520 HP. The combination of higher power and greater mass allows the Cat^® D10N to move larger loads more efficiently, resulting in an easy 10–15% production advantage over the Cat^® D9L. In addition, main hydraulic pressure was increased by 12.5%, further enhancing overall machine performance.

The dozers “floating” bogie action, created by the suspended undercarriage, absorbs up to 50% of impact loads on undercarriage components. Tubular track roller frames provide superior resistance to twisting and bending compared with conventional box‑section frames. Proper alignment is maintained by a pinned equalizer bar and pivot shaft supported by sealed, lubricated bearings.

The Cat^® D10N Semi‑Universal (SU) blade is 7.5% larger than that of the Cat^® D9L, increasing capacity to 22.56 cubic yards, while the Universal (U) blade grew by 8.5% to 27.34 cubic yards. The cutting-edge angle was also sharpened, allowing faster and easier penetration and delivering a 13% improvement in traction effectiveness.

CCM’s production of the legendary Cat^® D10N in 1:48 scale will honor a machine that marked a major milestone in Caterpillar^® dozer history. Three highly detailed collector variants are planned—the U‑Blade, the SU‑Blade, and the C‑Blade—each engineered to faithfully represent its real‑world counterpart. We look forward to sharing additional details as development continues. Collectors who wish to request these models for their collection may do so by clicking here.
