About this family
The Rigid Grading and Ditching Bucket is made for mini-excavators. It is used for ditch maintenance, grading and slope work. It’s available in sizes from 600 mm to 1800 mm, with capacities from 43 dm3 to 511 dm3. It is built from S355JR2 and Hardox® steel, with an HB500 cutting edge. The top section is rigid, and wear bars reduce wear on the bucket bottom. A bolt-on cutting edge is available, and the options include suction relief holes for sticky soil and drainage holes.
Seven sizes cover machines from 0.6 to 10 t, GBP-10 through GBP-95, in widths from 600 to 1800 mm. Capacity runs from 43 to 511 litres (SAE) and weight from 29 to 260 kg.
The body is S355JR2 and Hardox® steel with an HB500 cutting edge, a reinforcement bevel, a round inner profile, a top bent section, drainage holes and protected weld seams at the bottom. Options are a recessed adapter bracket, a reversible HB400 cutting edge, a rear HB500 cutting edge, HB500 cutting edges on the front sides and wear bars. On request it gets suction relief holes, so sticky soil drops out instead of holding to the bottom.
The quick coupler bracket follows the size, from S30, MS01 and M02 on GBP-10 up to S45, S50, MS08, M10, HS08, CW10 and OQ45 on GBP-95.
