The DBF is a digging bucket with a flat top, for excavators that work with a quick coupler. The flat top is made for a quick coupler, so the bucket changes over quickly between digging jobs. Seven sizes, DBF-120 to DBF-500, cover machines from 10 to 50 t.

  • Foundations, trenches, construction and demolition work
  • A size picked from the model table, built as Economy, Standard or Heavy Duty

Choose DB instead if

  • The bucket fits directly on the machine or on an SW or CW bracket

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
