S-System quick coupler system
These are the S-System sizes our model tables print. Open a size to see the attachment models that list it. The bracket for your machine is confirmed with your quote.
8 sizes.
We make a quick coupler for this system.
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.

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.
