Top Features

Power and Performance

  • Powered by Komatsu 3D88E-7 Tier 4 Final compliant engine features high pressure electronic fuel injection and a Diesel Particulate Filter (DPF).  No Diesel Exhaust Fluid or selective catalytic reduction system is required.  All daily maintenance items are access from the right side of the machine.
  • High engine and hydraulic efficiencies work together to provide up to a 5% fuel savings compared to the former PC30MR-3.
  • Extensive use of steel castings adds durability and strength for a long service life.
  • Auto idle and auto idle shut down systems help reduce nonproductive idle time and help reduce fuel consumption.

Minimum Swing Radius

  • The PC30MR-5 short tail swing design with swing boom is designed to fit into confined spaces.
  • The swing boom allows the machine to excavate and trench alongside walls or buildings.
  • A rounded outside corner cab/cab design allows the upper structure to revolve within the same radius as the counterweight without worry of contacting jobsite obstructions.

Operator Comfort

  • Standard ROPS and OPG Level 1 compliant canopy has no structures in front of the operator for excellent work area viewing.
  • An Optional ROPS and OPG Level 1 compliant enclosed and climate controlled ROPS cab provides a comfortable four season operator environment.
  • A midrise adjustable seat with pilot joysticks, wrist rests and 3” seat belt are standard.
  • Full color 3.5” LCD monitor provides machine information and makes selecting machine setting easy

Simple and Convenient Maintenance

  • A tilt up cab platform and large service compartment doors provide help simplify daily inspection periodic maintenance. The tilting platform provides unimpeded access to the engine and hydraulic components.
  • Komtrax level 5 telematics system provides GPS location, fuel, hours and vehicle performance information wirelessly to or a smart phone.
  • Komatsu advanced diagnostic system does not require a laptop or additional software to use.
  • Komatsu Equipment Management Monitoring System (EMMS) displays abnormality and maintenance information on the monitor screen to help prevent a minor problem from becoming a major one.
  • Maintenance intervals are monitored and easily displayed in the monitor


  • A shorter arm and boom gives the PC30MR-5 greater arm digging forces and better lift over the front than the PC35MR-5 making it an excellent general excavation and trenching machine.
  • Standard auxiliary hydraulic system with one way and two way flow extends versatility by simplifying installation of a wide range of hydraulic attachments and hammers.
  • A standard ISO/Backhoe pattern change valve simplifies changing control patterns to suit different operator preferences.
  • A standard blade for light dozing and backfilling also improves digging and lifting stability.
  • Two rubber and one steel track design provide a wide range of undercarriage options for work on asphalt/concrete surfaces, construction sites or rough ground.
  • Major components are built to high Komatsu quality standards and designed to work together for maximum hydraulic and performance efficiency.
