Choosing mini excavators for the job

Compare tail swing, machine width, blade configuration, transport weight and auxiliary hydraulics against the actual work. Trailer and tow-vehicle limits can be as important as digging performance.

Machine types and configurations

Micro excavators
Compact conventional-tail
Reduced-tail-swing
Zero-tail-swing
Cab and canopy configurations

Specifications that matter

Specification	Why it matters
Operating and transport weight	Check the travel configuration against trailer space, access restrictions and route requirements.
Overall width	Check the travel configuration against trailer space, access restrictions and route requirements.
Digging depth	Shows whether the configured machine fits the required work envelope.
Tail overhang	Check clearance behind the machine throughout its swing, especially near walls and traffic.
Auxiliary flow	Determines powered-attachment capability and circuit requirements.
Blade dimensions	Must suit the material, work envelope, machine geometry and configuration.
Coupler type	Match the exact attachment interface, locking system and hydraulic connections.
