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 than 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 satellite 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.
