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.

DBF is for
- Excavators that change attachments on a quick coupler
- 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

Typical jobs
The DBF Excavator Quick Coupler Digging Bucket is used for:
- Large-scale excavation projects requiring frequent attachment changes (foundations, basements, trenches)
- Construction and demolition work
- Jobsites where one excavator changes often between several attachments
- Mining and quarrying (Rock version)
- Jobs where an attachment change must not keep the excavator standing for long
Tell us the machine and the job and we confirm the bucket size.
Which coupler is on your machine?
Pick the system on your machine and we put it in your enquiry. We check the bracket before we send the quote.
How to measure your coupler
Not sure which system it is? Three measurements tell us which bracket you need.
- Measure the diameter of both pins.
- Measure the distance between the pin centres.
- Measure the width between the inside faces of the ears.
If the coupler has a make or type printed on it, send that too.
