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

Drawing of a bracket with the pin diameter (1), the pin centre distance (2) and the ear width (3) marked

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.

S50: DBF - flat-top digging bucket for quick coupler

Questions about S50

What machine weight is S50 for?

Our S50 coupler is listed for machines of 5–12 t in our coupler catalogue.

Do you make the S50 coupler or only the brackets?

Both. We make the S50 quick coupler and the attachments with S50 brackets.

Is the S50 coupler automatic or manual?

Our S50 coupler comes as: automatic, manual, tilt-swivel.

Which attachments do you make with S50 brackets?

31 families with 32 models, starting with DBF - flat-top digging bucket for quick coupler, RDBF - flat-top skeleton DBF bucket on rods, GDH - heavy duty hydraulic grading & ditching bucket. The full list is at the top of this page.

How do I check which coupler my machine has?

Use the coupler check on this page: pick the coupler you see, or follow the measuring steps. A photo of the coupler also works.

How do I get a price for S50 attachments?

Use the price button at the top of this page or the price link on any model row. Name your machine and we reply with a price for S50 attachments.

S is the Swedish quick coupler standard. The size number sets the pin diameter and the pin spacing, so the size decides the bracket, not the make of the machine.

The quick coupler we make for this system: QC-S - S-System Scandinavian quick-coupler.

Every quick coupler is tested before dispatch.

Variant: Mechanical and hydraulic
Safety lock: Rear mechanical safety lock on both versions; pilot operated check valve on the hydraulic version only
