Welded to EN ISO 3834-2. Agree it as a standing term of supply and the EN 10204 3.1 certificate ships with every attachment. You also get the CE declaration of conformity for every attachment. See the certificates.
Message us on WhatsAppPhotos and voice notes are welcome.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.
Before you order: check the interface
The weight class of the Komatsu PC20MR-2 sizes the attachment. It does not tell you the pin diameter, the pin spacing or the stick width, and those decide whether an attachment fits. Measure them on the machine, or send us the measurements of the bucket it runs today.
On a mini excavator the weight of the attachment counts for more than on a larger machine, because every kilogram of bucket is taken from lift capacity and stability. A narrow trenching bucket and a wide grading bucket are the usual pair, and many machines run a small quick coupler to change between them.
Quick coupler brackets at this weight
In our model tables, the attachments listed for the Komatsu PC20MR-2 at its weight are built with these brackets. Each code opens the models that list it.
- Measure the diameter of both bucket pins.
- Measure the distance between the pin centres.
- Measure the inside width between the stick ears.
- If the machine runs a quick coupler, note its make and type.

What the PC20MR-2 figures mean for its attachments
- The main pump delivers up to 53.9 l/min at 245 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 2,750 mm. That is the deepest trench it can open.
- Komatsu offers arms from 1,015 to 1,365 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Komatsu lists buckets from 250 to 550 mm wide for this machine.Our sizes in that range: GP - general purpose digging bucket (GP-30, GP-40); GPL - general purpose digging bucket (GPL-30, GPL-40); BDP mini - clay digging bucket for mini-excavator (BDP-30, BDP-40); DS mini - Scandinavian deep digging bucket for mini-excavator (DS-30, DS-50); KS mini - cable bucket for mini-excavator (KS-20); KSV mini - Scandinavian profile cable V bucket for mini-excavator (KSV-20)
- Komatsu lists bucket capacities from 0.035 to 0.085 m³.
- Bucket breakout force is 18.8 kN and arm crowd force 13.6 kN. That is the force a bucket or ripper works with at the tooth.
- Komatsu gives a lifting capacity of 1,550 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- Engine power is 15.7 kW.
