Fuel-Efficient Hydraulic Excavator


With the same tight tail swing radius as its predecessor and up to 4% less fuel consumption compared to the previous model, PC138USLC-11 hydraulic excavator is ideal for utility and highway applications working in confined spaces. 


This new EPA Tier 4 Final certified model uses an SAA4D95LE-7 engine with a Komatsu Diesel Oxidation Catalyst (KDOC) and a Selective Catalyst Reduction (SCR) system with Diesel Exhaust Fluid (DEF) injection. The engine requires no diesel particulate filter or regeneration.


The PC138USLC-11’s contoured cab profile and sliding door allow the cab to swing within the same radius as the counterweight. A larger counterweight mass remains standard, giving the PC138USLC-11 equal or better lift capacity than conventional models in the same size class.


Tier 4 final Certified Engine Technology:

  • Powerful, efficient, SAA4D95LE-7, 4.4 L, 97.2 Net HP engine.
  • Komatsu Diesel Oxidation Catalyst (KDOC) after treatment system provides 100% passive regeneration.
  • Exhaust Gas Recirculation (EGR) to reduce NOx emissions.
  • Selective Catalyst Reduction (SCR) system, with Diesel Exhaust Fluid (DEF) injection used to meet EPA Tier 4 Final NOx requirements.
  • SCR catalyst has no scheduled maintenance and a life expectancy similar to that of the engine.



New Performance Features:

  • A large, 7630 lb. (3460kg) counterweight mass provides excellent lift capacity.
  • Komatsu hydraulic technology matches engine speed and hydraulic pump output for optimal performance.
  • Up to four percent lower fuel consumption than the previous Dash 10 machine.                      
  • New LCD monitor tracks maintenance and issues alerts about upcoming service and machine needs.
  • KOMTRAX and new monitor panel provide vital machine data for easy monitoring and quick operator action.
  • New Operator ID system provides KOMTRAX data to track operators, applications, and machine operation for up to 100 individual ID codes.
  • Six working modes (P, E, L, B, Att-P, Att-E) with energy-saving guidance incorporated into the monitor panel.
  • New temperature controlled viscous fan clutch reduces parasitic load on the engine and helps reduce sound levels.


Comfortable Cab Design - Standard Features Include

  • Upgraded high-resolution, LCD color monitor panel incorporates the standard rear view camera display with gauges.  “Ecology-Guidance” provides fuel-saving information to the operator.
  • ROPS certified cab design conforms to ISO 12117-2 and meets the ISO 10262 level one Operator Protective Guard (OPG) standard.
  • New, standard, high capacity, high back, heated, air-ride seat.
  • Auxiliary jack to connect mp3 players or other digital devices.
  • Two 12 volt power ports in the cab.
  • Standard secondary engine shutdown switch.
  • New, enhanced attachment control stores up to 10 attachments in the monitor panel, with adjustable flow control. Two-way attachments also run in Economy mode.
  • Pattern change valve.


Conveniently Located Maintenance Locations:

  • Same side, ground-level access to engine oil and filters for ease of maintenance as the previous model.
  • Ground level, fuel and engine oil filter service.
  • 60 amp alternator.
  • Ground level, easy access to air filter and swing-out coolers.
  • Service platform in front of DEF tank.
