Before you order: check the interface

The weight class of the Komatsu PC30 MRx 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 PC30 MRx at its weight are built with these brackets. Each code opens the models that list it.

Brackets we build attachments with in this weight range. Not a confirmed fit.

  1. Measure the diameter of both bucket pins.
  2. Measure the distance between the pin centres.
  3. Measure the inside width between the stick ears.
  4. If the machine runs a quick coupler, note its make and type.

What the PC30 MRx figures mean for its attachments

  • The main pump delivers up to 73.1 l/min at 259.9 bar. That is the pump output of the whole machine, not the flow an attachment gets.
  • It digs down to 2,840 mm. That is the deepest trench it can open.
  • Bucket breakout force is 27.5 kN and arm crowd force 17.3 kN. That is the force a bucket or ripper works with at the tooth.
  • Engine power is 21 kW.
