Design & Performance Features

• Compact Track Excavator Design: Rubber-track undercarriage and compact footprint for maneuverability in tight spaces and low-impact ground travel.

• Strong Performance for Size: Sufficient horsepower and breakout forces to handle digging, trenching, back-filling, and material handling tasks typical of 4-ton class excavators.

• Hydraulic Versatility: Auxiliary hydraulic flow allows use of attachments (e.g., thumbs, augers, breakers), increasing machine utility.

• Durable Engine & Hydraulics: Kubota D-series diesel with proven reliability; hydraulic circuit supports consistent performance under load.

• Good Digging & Dump Reach: Excavation depth and dumping height enable efficient digging and loading of trucks or trailers.

• Operator Convenience: Compact width + rubber tracks make transport and job-site access easier compared to larger excavators.

• Balanced Power-to-Weight: Operating weight and power deliver adequate stability and breakout force without excessive ground pressure for a mid-size mini-excavator.
