Collection: Excavator Skeleton Buckets

Skeleton Buckets for Excavators

A skeleton bucket separates larger material from loose soil as the excavator works. Earth falls between the ribs, while rocks, roots and debris remain inside. It can save a second handling step during landscaping, utility work or site cleanup, although wet clay will screen less freely than dry ground.

Similar attachments may be described as screening or sorting buckets. A search for skeleton bucket excavator does not identify the required model by itself; width, weight, rib spacing and coupler geometry still matter.

Key Features

Bully Dog Equipment lists skeleton models made with T1 structural steel and AR400 components in high-wear areas. Versions for lighter machines have reversible bolt-on cutting edges. Larger digging models use replaceable pin-on teeth [Reference 1].

The main construction details include:

• Open ribs for releasing finer soil.
• Reinforced wear areas for abrasive ground.
• Cutting edges or teeth suited to the model.
• Widths for compact and full-size carriers.
• Multiple wedge and pin-on mounting options.

This design differs from a closed-floor rock bucket. Contractors who primarily need excavation or finishing can compare other Excavator Buckets, including Digging Buckets, Trenching Buckets and Clean-up Buckets.

"Choose rib spacing according to the material you want to retain. Flat stones, tangled roots and damp soil behave differently even when their dimensions look similar." — Bully Dog Equipment expert guidance

Applications

Choosing a skeleton bucket for excavator work is practical when larger pieces must be removed while usable soil stays on the site. The attachment can dig lightly and screen during the same cycle.

Common applications include:

• Separating rocks from landscaping soil.
• Removing roots from disturbed ground.
• Sorting mixed material during cleanup.
• Screening backfill near drainage trenches.
• Sifting rocky soil during land clearing.

A skeleton design is not a precision screen, so bucket spacing does not guarantee an exact final fraction. Compacted ground may first need Rippers, while Log Grapples are better suited to handling large timber and awkward roots.

Available Sizes

The smallest listed excavator skeleton bucket is a 36-inch model for 2–4 tonne machines. Other product cards cover 5–6, 6–10, 10–13, 11–16, 20–25 and 30–40 tonne classes. Published widths include 36, 42, 48, 54 and 66 inches.

Rib spacing varies rather than following one standard. Models for 2–6 tonnes use 3.5-inch spacing. The 54-inch buckets for 6–13 tonnes use 4 inches, while the 48-inch digging model for 11–16 tonnes returns to 3.5 inches. The 20–25 tonne version uses 4 inches, and the Extreme Duty model has a 4.5 × 6-inch pattern [Reference 2].

Weight ranges from 275 lb for the smallest attachment to 4,200 lb for the Extreme Duty version. The carrier must be able to handle the bucket itself as well as the retained material.

Compatibility

Tonnage is only the first compatibility check. The catalogue includes WBM and CWS wedge systems, Bobcat X-Change and configurations for several Caterpillar, John Deere, Hitachi, Kubota, Sany, Yanmar and Komatsu machines.

Before ordering, confirm the pin diameter, pin-centre distance, inside mounting width, coupler style and attachment weight. Bully Dog Equipment also mentions custom lugging for unlisted machines, subject to pricing and availability.

"Two carriers in the same weight class may use different mounting geometry. Confirmed measurements, not the tonne label alone, determine whether a bucket will connect correctly."

Owners reviewing the store's Mini Excavators should therefore verify the precise interface rather than assume that every compact machine shares one standard.

Why Choose Bully Dog Equipment

A buyer comparing an excavator skeleton bucket for sale can review published widths, weights, steel grades, rib spacing and available mounting systems. The range covers compact landscaping equipment as well as heavy-duty pipeline and excavation work.

Bully Dog Equipment operates from Vancouver and advertises Canada-wide shipping. Stock should be confirmed for the selected size and coupler. Its published warranty covers parts rather than labour, requires manufacturer pre-approval and provides three months of coverage for excavator attachments [Reference 3].

FAQ

What is a skeleton bucket used for?

It separates rocks, roots and debris from finer soil during digging, sorting or site cleanup.

What materials can it separate?

It can work with loose earth, gravel, stone, roots and mixed debris. Moisture and compaction affect screening.

Which excavator sizes are supported?

The current product cards cover machines from 2–4 tonnes through 30–40 tonnes. Coupler fit and lifting capacity must also be checked.

What spacing is available?

Published options include 3.5 inches, 4 inches and a 4.5 × 6-inch Extreme Duty pattern.

Is it suitable for landscaping?

Yes. It can remove stones and roots from loose soil or help prepare drainage areas when the spacing suits the material.
