SB is a grading and ditching bucket with a Dutch profile for excavators from 12 to 40 t. Its wider opening lets sticky soil fall out when the bucket is emptied, so it suits ditch cleaning and grading in clay.

About this family

Dutch profile ditching and grading bucket: the wider opening lets sticky soil fall out.

Six sizes, SB-160 to SB-400, come in widths from 1500 to 2500 mm, with a capacity of 583 to 2242 litres (SAE) and a weight of 357 to 1065 kg. The tip radius grows from 830 mm on the SB-160 to 1237 mm on the SB-400. The rib is standard. Options: a welded back cutting edge, horizontal wear bars and a reversible bolt-on cutting edge. Depending on the size, the listed couplers are CW20 to CW45, SW33, SW48 and SW66. Tell us the machine and we confirm the bucket size.

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.
