Komatsu Europe announces the launch of the D61EX/PX-24 dozer, an all-around performer and standout choice for any grading or earthmoving application. Along with improved comfort and a new automatic idling engine shut down
system, it features the widely recognized advantages of its predecessor and a new EU Stage IV engine with class-leading power and unrivaled fuel efficiency.

“The operator has a unique view on the blade thanks to the steeply sloped engine hood, a trademark of Komatsu dozers,” says William Groven, Product Manager at Komatsu Europe. “Combined with the optimized new engine and hydrostatic transmission control systems, productivity is boosted in all applications.”

The D61EX/PX-24 crawler dozer has a powerful and efficient 6.8 liter, 125 kW (168 hp), SAA4D107E-3, EU Stage IV emissions-certified engine with a “heavy-duty” aftertreatment system, a Komatsu Diesel Particulate Filter (KDPF) and a Selective Catalytic Reduction (SCR) system. The KVGT creates excellent engine response and helps to maintain a high level of passive regeneration, with no fuel wasted on cleaning the exhaust filter.

Komatsu’s target of high quality and lower costs for customers is met also by the increase of wear life for machine components. On the D61EX/PX-24, the final drive is now further protected from dirt and damage by a new triple labyrinth seal, for superior durability.

The new high-comfort cab has an air suspension high back seat, adjustable and heated. Possibilities for fleet management are expanded thanks to an upgraded high-resolution TFTLCD machine monitor, with ECO/POWER mode selection and operator identification. For the operator’s convenience, a shovel holder was added to the back of the machine.

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