The weight class of the Komatsu PW170ES-6 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.
At this weight the choice is mostly about the material. A general purpose bucket suits soil and gravel, a reinforced bucket with thicker wear parts suits mixed ground and broken rock, and the quick coupler on the machine sets the bracket every attachment needs.
Quick coupler brackets at this weight
In our model tables, the attachments listed for the Komatsu PW170ES-6 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.
- 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 PW170ES-6 figures mean for its attachments
- The main pump delivers up to 299 l/min at 318.7 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 5,720 mm. That is the deepest trench it can open.
- Its maximum reach is 8,886 mm.
- It dumps at up to 6,695 mm, so a truck or skip side has to sit below that height.
- Komatsu offers arms from 1,850 to 2,900 mm. A longer arm reaches further, a shorter one handles a heavier bucket.
- Komatsu lists buckets from 450 to 1,400 mm wide for this machine.Our sizes in that range: DB - heavy duty digging bucket (DB-190); SDB - heavy duty skeleton DB bucket (SDB-230); DBF - flat-top digging bucket for quick coupler (DBF-190); RDBF - flat-top skeleton DBF bucket on rods (RDBF-190); DSX - Nordic heavy duty digging bucket (DS-HD-190); CB - heavy duty hydraulic clamp bucket (CBR-190)
