About · Komatsu D65PXOverview
The Komatsu D65PX is a medium-to-large crawler bulldozer with an operating weight of 21,974 kg and an engine output of 217 hp. It is equipped with a blade capacity of 3.7 m3, positioning it as a capable production dozer suited to demanding earthmoving applications. The PX designation indicates a wide-gauge, low ground-pressure undercarriage configuration, making it appropriate for operation on softer or more sensitive ground conditions.
Typical applicationsWhere this machine is used
Machines in this class are typically deployed on civil engineering projects including road construction, site preparation, and large-scale grading operations. The wide-track undercarriage configuration extends the machine's suitability to wet or unstable ground, such as reclamation sites, landfill operations, and agricultural earthworks. Bulk material pushing and spreading on infrastructure projects represents the core productive use case for dozers of this weight and blade capacity.
Used-market inspectionWhat to check before buying
When inspecting a used D65PX, priority should be given to the condition of the undercarriage, as track components, rollers, and sprockets represent a significant portion of ongoing ownership costs in this machine class. The final drives and hydraulic system should be checked for leaks and smooth operation across the full range of blade and ripper functions. Engine hours should be verified against service records, and buyers should confirm that scheduled maintenance intervals have been observed and documented. A physical inspection by a qualified technician is recommended before purchase, and machines should ideally be assessed under working load conditions where possible.
Current marketPrice position
In the European market, the D65PX carries an average asking price of EUR 114,750, with a typical price range spanning EUR 84,600 to EUR 144,900 depending on age, condition, and specification. The machine competes directly with the Caterpillar D6 and the Liebherr PR 734, both of which occupy a comparable weight and power class. Buyers comparing options across these three models will find that pricing, parts network availability, and regional dealer support are key differentiating factors worth evaluating alongside the machine itself.
