About · Komatsu D51Overview
The Komatsu D51 is a mid-size crawler bulldozer with an operating weight of 14,260 kg and an engine output of 131 hp. It is equipped with a blade capacity of 3.36 m³, positioning it firmly in the medium dozer segment suited to demanding earthmoving and grading work. The machine competes on a specification level with other purpose-built dozers in its weight class.
Typical applicationsWhere this machine is used
Medium-class bulldozers such as the D51 are well suited to site preparation, road construction, land clearing, and bulk earthmoving tasks where controlled blade loads and machine maneuverability are priorities. Their operating weight and blade volume make them capable of sustained production work on construction sites, quarries, and civil infrastructure projects. They are also commonly deployed in pipeline corridor preparation and forestry access road construction.
Used-market inspectionWhat to check before buying
Inspection of a used crawler bulldozer in this class should focus on undercarriage wear, including track shoes, rollers, idlers, and sprockets, as these components represent a significant share of long-term operating cost. The blade cutting edge and push arms should be examined for straightness and wear. Engine compartment checks should cover coolant condition, oil levels, and any visible leak points around the final drives. Service history documentation, particularly evidence of scheduled filter and fluid changes, adds meaningful confidence to any purchase decision. Hydraulic cylinder seals and blade tilt and pitch functions should be tested under load where possible before committing to acquisition.
Current marketPrice position
In the European used-equipment market the Komatsu D51 carries an average asking price of EUR 73,667, with a typical price range running from EUR 70,000 to EUR 77,500. This positions the model within a defined band relative to comparable machines from John Deere, represented by the 700K, and Liebherr, represented by the PR716. Buyers evaluating the D51 should benchmark condition, configuration, and attachments against those competitor models when assessing value within this price corridor.
