How to choose the right excavator size.

Operating weight is only the starting point. Match the machine to access, digging depth, hydraulic attachments, transport limits and local emissions rules.

Weight class	Typical work	Key checks
1–2 tonnes	Small landscaping, narrow access, light trenching	Machine width, transport weight, canopy/cab, variable undercarriage
2–4 tonnes	Residential construction, utilities, landscaping	Zero-tail swing, digging depth, auxiliary hydraulics, quick coupler
4–6 tonnes	Municipal work, road maintenance, rental, heavier trenching	Digging force, stability, cab comfort, service access
6–14 tonnes	Roads, foundations, utilities and general construction	Emissions certification, hydraulic flow, transport dimensions, telematics
15–30 tonnes	Earthmoving, infrastructure and quarry support	Production rate, fuel use, undercarriage life, fleet support and resale

Questions to ask before buying

What is the narrowest access width and maximum transport height?
What digging depth and reach does the job require?
Will you run a breaker, auger, grapple or tilt attachment?
Which emissions standard applies in the destination country?
Where will filters, seals, hoses and undercarriage parts be sourced?
What is included in warranty and who performs local repairs?
