FAQ
Which excavators is this digging bucket suitable for?
This digging bucket is designed for excavators in the up to 5.5 t weight class and is suitable for excavations, bulk digging and earthmoving – high bucket capacity for fast mass excavation. Compare your machine's operating weight with the technical data to avoid overload and premature wear.
Which mounting system does the attachment have?
The attachment has a MS03 mount and is compatible with the Lehnhoff quick coupler system. This is not an original Lehnhoff product. Please compare the mount designation (e.g. MS03) with the marking on your quick coupler or the machine manual.
What class is this digging bucket?
This digging bucket is assigned to class KL3 and designed for the corresponding load class. The class determines the maximum machine size. Always follow the weight-class table in the technical data.
What is the working width of the attachment?
The working width is 700mm and is suitable for excavations, bulk digging and earthmoving – high bucket capacity for fast mass excavation. Choose the width to match the planned trench or excavation. An excessively wide bucket increases backfilling effort, while a bucket that is too narrow increases the number of digging cycles.
How many teeth does this digging bucket have, and can they be replaced?
This digging bucket is equipped with 5 teeth. The teeth are bolted and can be replaced individually without replacing the entire bucket. Replacement teeth are available directly from us.
What material is this digging bucket made from?
The main body is made from S355J2+N structural steel and the cutting edge from HB500 wear steel. 8 mm S355J2+N side cutters protect welds and side plates. Buckets are supplied primed and painted and include a 1-year warranty on weld seams.
Is this digging bucket available in other widths or mounting systems?
Yes. Variants mainly differ in working width and application. Use the filters to find versions compatible with your mount and excavator class. Need a special size or a different mount? Contact us – we also manufacture custom sizes.
What is included in the delivery?

Excavator digging buckets – Precise Excavation for Every Construction Site
digging buckets are among the most frequently used attachments in excavation, sewer, and pipeline construction. They are specifically designed for excavating trenches, foundations, and building pits, allowing for clean, controlled material pickup.
Depending on working width, volume, and bucket class (KL), the digging bucket can be optimally matched to the respective machine and application. A well-matched volume ensures efficient work while maintaining control over the excavation.
Depending on the machine and application, our digging buckets are available with MS mount (Lehnhoff-compatible), CW mount (Verachtert-compatible), pin-on attachment, or a custom special attachment upon request.
