Komatsu Compact Hydraulic Excavator

Staff | September 28, 2010

The PC35MR-3 compact hydraulic excavator from Komatsu America Corp. is designed to bring increased production and added operator comfort to contractors in a variety of construction, utility, landscaping and other applications.

The machine is equipped with the latest KomtraxTM technology which sends machine operating information to a secure website utilizing wireless technology. Data such as operating hours, machine location and fuel levels are relayed to the web application for analysis. The Komtrax fleet monitoring system increases machine availability, reduces the risk of machine theft and provides a wealth of other information to drive business efficiency.

Operator Comfort

For operator comfort, the unit allows easy entry and egress due to the wide entrance and well placed handholds. A fully adjustable suspension seat with retractable seatbelt lessens fatigue, and pilot proportional joystick controls with wrist rests permit continuous, comfortable operation.


The PC35MR-3 is a member of the minimum swing radius family of compact excavators which enables the operator to focus on the work in front and worry less about rear swing impacts in confined areas. The unit accomplishes this task while maintaining high lift capacity and stability. It has an operating weight of 7,909 pounds and features a maximum digging depth of 11 feet 4 inches. The standard thumb mounting bracket and auxiliary hydraulics simplify hydraulic thumb installation enhancing the machine's capability and versatility. Optional Power Angle Blade allows the operator to angle the blade 25 degrees to the right or left, increasing the excavator's productivity; making it especially useful when backfilling trenches.


Deriving power from a Komatsu engine with a net horsepower of 28.9, the direct injection engine meets EPA emissions requirements and is fuel efficient without sacrificing power or efficiency. The X-track frame deters the build-up dirt and debris saving the operator valuable time when cleaning the machine and the single, large diameter swing pin ensures long life and durability of the boom swing mechanism.

Service and Maintenance

To simplify maintenance, Komatsu equipped the excavator with numerous features. The operator compartment tilts up for providing access to the hydraulic components and the back of the engine (starter/alternator); the wide opening engine cover and side covers provide outstanding access to daily checkpoints; and the radiator and oil cooler are side by side making them easy to inspect and clean, ensuring that only the cleanest freshest air reaches each component. Extended greasing and service intervals make it easier to schedule maintenance.
