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
213

Not sure which system it is? Three measurements tell us which bracket you need.

  1. Measure the diameter of both pins.
  2. Measure the distance between the pin centres.
  3. Measure the width between the inside faces of the ears.

If the coupler has a make or type printed on it, send that too.

What the KX027-4 figures mean for its attachments

  • Its auxiliary circuit is rated at 47.3 l/min and 225 bar. A breaker, auger, tilt rotator or other hydraulic tool states the oil flow it needs, so choose one whose range includes this figure.
  • It digs down to 2,740 mm. That is the deepest trench it can open.
  • Kubota offers arms from 1,050 to 1,300 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
  • Bucket breakout force is 22.1 kN and arm crowd force 12.9 kN. That is the force a bucket or ripper works with at the tooth.
  • Kubota gives a lifting capacity of 1,440 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
  • For transport it measures 4,370 x 1,400 x 2,420 mm (length, width, height).
  • Engine power is 17.7 kW.

Before you order: check the interface

The weight class of the Kubota KX027-4 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 Kubota KX027-4 at its weight are built with these brackets. Each code opens the models that list it.

  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.
