The PC78US-10 hydraulic excavator from Komatsu America Corp. has a Tier 4 Final engine that doesn’t require a diesel particulate filter (DPF) or Diesel Exhaust Fluid (DEF).

The PC78US-10 allows operators to work with ease in confined spaces, thanks to the tight tail-swing radius, offset boom and contoured cab design inherited from its predecessor. What is new to the machine is an up to three percent increase in productivity and an up to five percent drop in fuel usage with no loss of performance.

“This is the ideal machine for anyone working on urban, utility contracting or home building worksites,” said Rob Orlowski, Komatsu America product manager. “Between the extra horsepower and the generous use of boom-area castings, operators should feel confident clearing rocks, tree stumps and similar kinds of debris.”

In addition to requiring no DPF or DEF, the SAA4D95LE-6 3.26-litre, 55-hp engine has a variable flow turbocharger for precise operation and long life. It also has a Komatsu Diesel Oxidation Catalyst aftertreatment designed specifically for the engine to provide 100 percent passive regeneration and an exhaust gas recirculation system added to reduce NOx emissions.

Operator-friendly enhancements include a new side-by-side radiator and oil cooler to simplify cleaning and the placement of all major maintenance items in areas ground-level accessible from either the engine hood, right-side hood or side-service doors.
