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 PC20R-5 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 PC20R-5 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 PC20R-5 figures mean for its attachments
- The main pump delivers up to 36 l/min at 210 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- Komatsu lists this quick coupler for it: Lehnhoff quick-couplers. The bracket on every attachment has to match the coupler.
- It digs down to 2,370 mm. That is the deepest trench it can open.
- Its maximum reach is 4,030 mm.
- It dumps at up to 2,760 mm, so a truck or skip side has to sit below that height.
- Komatsu offers arms from 965 to 1,215 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Komatsu lists buckets from 250 to 450 mm wide for this machine.Our sizes in that range: BDP mini - clay digging bucket for mini-excavator (BDP-30); 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 0.02 to 0.03 m³.
- Komatsu gives a lifting capacity of 610 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
- Engine power is 11.8 kW.
