PC88MR-10 Small Hydraulic Excavator
The PC88MR-10 is a link between minis and mid-size excavators. The PC88MR-10 has a swing boom, tight tail swing, three track options and backfill blade like a mini but is built to have the reliability and durability of larger excavators.
Komatsu Diesel Oxidation Catalyst (KDOC)
The new Komatsu Diesel Oxidation Catalyst (KDOC) has an integrated design that does not interfere with daily operation. This smart and simplified system removes soot using 100% "passive regeneration" without the need for a Diesel Particulate Filter. The KDOC is a simple design and does not have a scheduled service interval like a DPF and is designed for long life with no scheduled maintenance required. For owners, this means lower owning and operating costs due to less complexity and seamless operation.
Newly designed Variable Flow Turbocharger
A newly designed variable flow turbocharger features simple and reliable technology that varies the intake airflow. This provides optimum air flow under all speed and load conditions producing cleaner exhaust gas without sacrificing power and performance.
Efficient Hydraulic System
The PC88MR-10 uses a Closed-center Load Sensing System (CLSS) that improves fuel efficiency and provides quick response to the operator's demands.
The PC88MR-10 also introduces new technology to enhance the engine and hydraulic pump control. This total control system matches the engine and hydraulics at the most efficient point under different load conditions. There have also been improvements in the main valve and hydraulic circuit to reduce hydraulic loss, resulting in higher efficiency and lower fuel consumption.
Reduced Up To 4% Fuel consumption*

High Rigidity Work Equipment
Booms and arms are constructed with thick plates of high tensile strength steel. In addition, these structures are designed with large cross-sectional areas and large one piece castings in the boom foot and the boom tip. The result is work equipment that exhibits long term durability and high resistance to bending and torsional stress.
The swing boom allows the PC88MR-10 to work where a standard boom excavator could not.
Rear View Monitoring System
The operator can view the rear of the machine with a color monitor screen.
Every PC88MR-10 comes standard with a 2332mm 7'7" blade. A wide angle blade is also available as an option.
Pattern Change Valve Standard
A pattern change valve is conveniently located below the cab, making switching from excavator controls to backhoe controls quick and easy.
