Power and versatility

February 2017 — Komatsu Europe announces the introduction of the D51EX/PX-24 dozer to the European market. This latest model completes the range of Komatsu EU Stage IV compliant hydrostatic dozers. With its new 4-cylinder engine, ECO and POWER modes and automatic idling shut-down system, the D51EX/PX-24 can drastically increase customer’s profitability. Thanks to its steeply downwards sloped engine hood, the operator can experience an outstanding all-round visibility, which makes the Komatsu D51EX/PX-24 a preferred dozer for any application.

The new D51EX/PX-24 offers class-leading productivity and can achieve an increased fuel efficiency of up to 15% compared to the previous model


“Komatsu puts the operator’s needs as the highest priority and continuously works to optimize engine and hydrostatic transmission technology” says William Groven, Product Manager at Komatsu Europe. “The new D51EX/PX-24 offers class-leading productivity and can achieve an increased fuel efficiency of up to 15% compared to the previous model” 

Available in either long track-on-ground (EX) or low ground pressure (PX) configuration, the D51EX/PX-24 crawler dozer offers flotation and weight distribution options, tailored to customers’ applications. The new Komatsu dozer features a powerful and efficient 4.5 litres, 98 kW (131 HP), SAA4D107E-3 EU Stage IV emissions-certified engine, with a “Heavy-duty” aftertreatment system. A Selective Catalytic Reduction (SCR) system is now added to the Komatsu Diesel Oxidation Catalyst (KDOC), which requires only passive regeneration - with no fuel wasted to clean the exhaust filter.

The D51EX/PX-24 proposes superior Komatsu durability and lower operating costs to customers. Wear life of Komatsu’s high quality components was further increased, and a new triple labyrinth seal now protects the final drive from dirt and damage.

The new high-comfort cab has an adjustable and heated, air suspension high back seat. Possibilities for fleet management are expanded thanks to an upgraded high-resolution TFT-LCD machine monitor, with ECO/POWER mode selection and operator identification.Job site safety is a key Komatsu value and a factory integrated rear view camera is included as standard. For the operator’s convenience, a shovel holder was added to the back of the machine.

The latest KOMTRAX™ telematics, and the Komatsu Care® maintenance program, offer top fleet management and support, protect the machine against misuse and guarantee maximum efficiency and uptime.
