The teeth and adapters are the tooth-system maker's own parts.

DB is for

  • Digging and trenching in soil on building and utility sites
  • Foundations, basements and site preparation
  • Loading and moving bulk material such as soil and rubble
  • A size picked from the model table, built as Economy, Standard or Heavy Duty

Choose DBF instead if

  • Your excavator changes attachments on a quick coupler and a flat-top bucket suits it

Choose DSX instead if

  • You dig rocky ground or abrasive material and want a Nordic profile bucket with a Hardox® body

Choose DBS instead if

  • You dig rock and want the bucket designed for your machine and that rock
  • Teeth, adapters, side cutters and wear protection should be chosen for your job
  • You need a factory acceptance test record with the bucket
