Overview

​Are you after a small excavator but demand big features? Take a look at the Komatsu MR-3 range.

The MR-3 units are smaller thatthe their larger counterparts; however they are stacked with huge features such as:
- Komatsu's Closed-center Load Sensing hydraulics for powerful performance,
- Large operator stations with leading ergonomics for ease of operation and comfort,
-Class leading accessibility for maintenance and servicing through tilting cabin platforms.

Additional to the above features, we can offer flexibility with your configuration via selection of cabin or canopy; and a track selection of rubber, steel or roadliner undercarriage.

As the MR-3 units are equipped with KOMTRAX satelite monitoring as standard; asset management, control and security is a breeze as you can easily track and obtain the latest information with minimal fuss.

Due to their integrated design, they are robust, durable and offer low cost ownership.
