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

SpecificationWhy it matters
Operating and transport weightCheck the travel configuration against trailer space, access restrictions and route requirements.
Overall widthCheck the travel configuration against trailer space, access restrictions and route requirements.
Digging depthShows whether the configured machine fits the required work envelope.
Tail overhangCheck clearance behind the machine throughout its swing, especially near walls and traffic.
Auxiliary flowDetermines powered-attachment capability and circuit requirements.
Blade dimensionsMust suit the material, work envelope, machine geometry and configuration.
Coupler typeMatch the exact attachment interface, locking system and hydraulic connections.

Before buying used

  • Check boom swing, slew play and blade pins
  • Inspect rubber tracks, sprockets and lower rollers
  • Confirm auxiliary lines and coupler operation with the intended work tools
Ownership costs to consider

Cost drivers

  • Rubber tracks and lower rollers
  • Boom-swing and slew components
  • Pins, bushings and coupler wear
  • Compact emissions systems
Plan your transport

Transport checklist

  • Check trailer payload after attachments
  • Measure actual width and overall height
  • Secure buckets and tools separately where required
  • Verify tow vehicle, hitch and axle ratings independently
