The attachments buyers in your market ask for first, sized for the KX019-4 LPG.

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.

Send me the spec sheet for my machine

What the KX019-4 LPG figures mean for its attachments

Its auxiliary circuit is rated at 27.7 l/min and 216 bar. A breaker, auger, tilt rotator or other hydraulic tool states the oil flow it needs, so choose one whose range includes this figure.
Kubota lists a 470 mm wide bucket for this machine. Compare that with the bucket widths in the table above.
Kubota lists a bucket capacity of 0.04 m³.
Bucket breakout force is 15.9 kN and arm crowd force 7.8 kN. That is the force a bucket or ripper works with at the tooth.
Kubota gives a lifting capacity of 610 kg. Check a heavy grab or hammer, plus its load, against the full load chart.
Engine power is 14.5 kW.

KX019-4 LPG	1.775 t	27.7 l/min
Kubota U18-5	1.76 t (-0.015 t)	27.7 l/min
Kubota U17-5	1.705 t (-0.07 t)	27.7 l/min
Caterpillar 301.5	1.77 t (-0.005 t)	33 l/min (+5.3)

Figures as each maker publishes them. A difference is shown only where both machines have a published value.

Questions about the KX019-4 LPG

What bucket width fits the KX019-4 LPG?: Kubota lists a 470 mm wide bucket for it. Compare that with the sizes above.
Can the KX019-4 LPG run a hydraulic attachment?: Yes, if the tool's rated range covers the auxiliary circuit: 27.7 l/min at 216 bar.

Before you order: check the interface

The weight class of the Kubota KX019-4 LPG 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 KX019-4 LPG 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.
