- Weight Class
- 10–30 t
Attachments for large excavators from 10 to 30 t, built for daily production work. Many families are available with Hardox® wear parts.
GD Rigid grading & ditching bucket, 12–40 t
The rigid body has no tilt joint, so there are no hoses or cylinders to connect. It is used to grade surfaces and clean ditches.
GDH Heavy duty hydraulic grading & ditching bucket
The hydraulic tilt grading bucket shapes slopes and levels uneven ground.
Digging & sorting buckets
Digging and sorting buckets for excavators in several capacities, for digging and material handling.
Standard Earthmoving / heavy duty
DB Heavy duty digging bucket
A digging bucket for most materials, with a rock version for harder ground.
SDB Heavy duty skeleton DB bucket
The SDB separates material as you dig: soil falls through the ribs while stone, rubble and roots stay in the bucket.
RDBF Flat-top skeleton DBF bucket on rods
Interlocking steel rods replace the solid bottom, C45 as standard and Hardox® as an option. Soil sifts out from the rocks while you dig trenches, drains and pipe bedding.
DSX Nordic heavy duty digging bucket
Nordic profile heavy duty digging bucket for excavators from 14 to 40 t, made of Hardox® 450 for rocky ground.
Ditching, grading, sloping buckets
Buckets for ditch cleaning, grading and sloping.
SB Dutch profile grading & ditching bucket
The Dutch profile has a wider opening, so sticky soil falls out. Use it for grading and ditch work in sticky soil.
DCB Grading & ditching bucket with round profile
The round profile lets material flow out with little drag. Use it to grade surfaces and to dig and clean ditches.
PS Scandinavian universal / grading bucket
A Scandinavian grading profile, used for grading and levelling.
PSH Hydraulic swivelling grading bucket
A cylinder swivels the PS bucket, so you set the angle of the cutting edge from the cab. It grades slopes and verges while the machine stays where it is.
Special use buckets
Special use buckets: hydraulic clamp buckets for gripping, profile buckets for trenches, and buckets with custom angles for specific jobs.
CB Heavy duty hydraulic clamp bucket
A hydraulic clamp arm closes onto the load, and a double pilot check valve holds it shut if a hose fails. The excavator digs, then picks up rubble, stumps, pipes and awkward stone.
Non-bucket attachments
Attachments other than buckets: grading beams for finishing, single rippers and multi-rippers for hard ground, and asphalt cutters for removing pavement.
TH Hydraulic thumb for excavator
The thumb grips against the bucket and folds back against the stick when you do not need it. The excavator picks up and holds rocks, logs, pipes and debris.
AC Excavator asphalt cutters
A 450 mm steel disc, symmetrical (ACs) or asymmetrical (ACa). It makes clean cuts in asphalt for road repairs, utility trenches and pavement and kerb work.
MR Heavy duty excavator multi-ripper
The MR multi-ripper enters the ground on several legs at once and breaks up and loosens compacted material.
RIP Heavy duty ripper
A single shank made of high-strength steel, with a protector over the shank. It breaks up hard soil, rock and frozen ground, so the material can then be loaded with an ordinary digging bucket.
DuoRIP - double ripper for root extraction
Two shanks go deep into the ground at once. It rips out root systems, large roots and stumps when land is cleared for a site.
GRB Excavator grading beam
A grading beam for excavators up to 30 t. It levels large areas for driveways, roads and building sites.
Compact excavator attachments
Nordic mini-ex buckets set No. 4
Nordic designs, most often coupled with S-System brackets.
PS mini - Scandinavian universal grading bucket for mini-excavator
The PS mini grading bucket has the Scandinavian profile. It is made for mini-excavators, for fine grading and finishing work.
PSH mini - hydraulic swivelling grading bucket for mini-excavators
A cylinder swivels the PS mini bucket, so you set the angle of the cutting edge from the cab. It finishes slopes and verges in tight places while the machine stays where it is.
Special use mini-ex buckets
Buckets with non-standard applications.
GKB mini - deep cable digging bucket for mini-excavator
The GKB Deep Cable Bucket lets a mini-excavator dig deep trenches for cables. It works in hard ground.
RGB Skeleton rod grading & sorting bucket
A rod floor lets fines fall through while stones, rubble and roots stay in the bucket. Material is sorted, graded and reused on site without a separate screen.
Other mini-ex attachments
Other attachments for mini-excavators.
LRS Short land rakes for mini-excavators
A shorter, narrower land rake for small machines working in tight plots and along boundaries. It pulls out roots and stones and lets the soil fall through.
RIP mini - ripper shank for mini-excavator
Mini-excavator rippers break up hard ground before trenching and foundation work.
MR mini - multi-ripper for mini-excavator
Multi-rippers for mini-excavators break up hard soil and debris when you prepare a site.
AC mini - asphalt cutter for mini-excavator
Asphalt cutter for mini-excavators. The 450 mm steel disc cuts asphalt for roadworks, repairs and utility trenches.

Machine makes and model names belong to their owners. Sieruta is not affiliated with them. We use the names only to show which machines we offer attachments for, by operating weight.
How to choose
Between 10 and 30 tonnes the machine is on site to move volume and the cycle repeats all day. An attachment that is only just strong enough costs money in wear parts and downtime. This page lists every Sieruta family with at least one model row rated for a carrier in that band: heavy-duty digging buckets, flat-top buckets drawn for a quick coupler, rigid and hydraulic grading and ditching buckets, the Dutch and Nordic profiles, the Scandinavian universal bucket, skeleton and rod buckets, the swivelling grading bucket, clamp buckets, rippers and multi-rippers, asphalt cutters, the grading beam, rakes and the hydraulic thumb. Each family page states its own steel grades, and the bracket is built to the coupler system on your machine. Send the carrier data with the model code and we confirm the fit and the wear package before production starts. For digging, the DB is the bucket for soil, trenches, foundations and bulk material, built as Economy, Standard or Heavy Duty in the sizes of its model table. When the ground is rock, choose its sibling, the DBS rock bucket. It is engineered to order: we design it for one machine and the rock it digs, and the teeth, adapters, side cutters and wear protection are chosen for that rock. Tell us the rock and the machine, and our engineers design the bucket around them.
- 1
Size the bucket to the cycle, not to the machine plate
On production work the right capacity is the one the carrier fills and lifts every cycle without slowing down. Heavier material means a smaller bucket at the same tonnage, so tell us what you dig and we size it from that rather than from the machine class.
- 2
Choose the wear package before the width
Cutting edges, side protectors, wear bars and the tooth system decide how the bucket ages in abrasive ground. A bucket that runs in sand and gravel needs a different package from one in clay, and retrofitting protection later costs more than ordering it.
- 3
Pick the profile by the finish the job needs
A digging bucket moves volume, a rigid grading bucket cleans a trench and levels, a hydraulic one shapes slopes from one position, a riddle bucket separates stone from soil. Naming the finish first usually settles the profile in one step.
- 4
Confirm the coupler system and its rating
At this size the coupler carries real load. Give us the system on the machine, for example CW30, CW40, S60, S70 or a pin-on fit with its dimensions, and we build the bracket to it so the tool changes over without an adapter in the load path.
- 5
Plan the whole set
A 20-tonne machine on a site usually needs a digging bucket, a wide grading bucket and one tool such as a ripper or a thumb. Ordering them together lets us build one bracket standard across the set and keeps changeover to a few minutes.
Questions we are asked
- Which carriers count as large here?
Machines from 10 to 30 tonnes. A family appears on this page when at least one model row of its table is rated for a carrier inside that band.
- What is the difference between the Dutch and the Nordic profile?
They are two shapes the market asks for. The Dutch profile is a wide ditching and grading bucket. The Nordic heavy-duty profile is drawn for hard digging. Both are listed here with their own model tables.
- Do I need a special build for this class?
Usually not. The families on this page are built in series and cover the carriers in this class. Send the machine model and we name the size that fits.
- Which tooth systems can I have?
The systems each family supports are stated in its model table, together with the number of teeth per width. Tell us what your other buckets run and we keep the fleet on one system.
- How do I know a bucket suits my coupler?
The family states the bracket systems it is built for. Give us the coupler on the machine and the model code, and we confirm the pairing in writing before anything is cut.
