A skeleton bucket is a GP bucket with gaps in it. That sounds simple, and the concept is — but getting those gaps right for your specific job changes everything. Too wide and you lose small rocks. Too narrow and the bucket plugs up with soil every second pass.
The basic function: you scoop mixed material, tilt the bucket to let soil and fines fall through the tines, and you're left with rocks, roots, chunks of concrete, or whatever else won't fit through the gaps. One motion, two sorted piles. That's it.
Where it earns its place is in work where separation matters. Rock-picking on newly broken agricultural land. Cleaning up a demolition site where you want to pull rebar and block chunks out of the fill before you truck it. Scraping packed horse manure and separating the fine compost from the coarser bedding. Clearing a brushy field where you want the topsoil to stay put but the stumps and rocks to go.
The key thing to understand is that a skeleton bucket doesn't dig the way a GP bucket does. The tines break soil and let it fall through rather than containing it. You scoop, you tilt and shake — sometimes literally agitating the bucket by cycling the loader arms — and the fines drain out. It's a sifting motion more than a loading motion.
Spacing is the first thing you should spec out, and it drives everything else. Common options run from 2" to 4", with 3" being the middle ground most operators start with.
| Tine Spacing | What Falls Through | Best Use |
|---|---|---|
| 2" | Fine soil, sand, small fines | Asphalt millings, compost, fine aggregate separation |
| 3" | Soil, gravel under 3" | General rock picking, ag field clearing, landscaping |
| 4" | Everything under 4" including gravel | Demolition debris, large rock separation, construction cleanup |
The forum consensus, and it's consistent across r/Skidsteer and TractorByNet discussions: if you're unsure, go 3". It's the most versatile spacing for mixed agricultural and landscaping work. Two-inch is genuinely useful for fine separation work (asphalt millings, processed gravel sorting) but plugs easily in wet clay conditions. Four-inch moves faster but leaves small rocks behind — fine for demolition, not ideal if you're trying to clean a horse paddock.
This is a subtler choice but matters in practice. Round bar tines shed material more easily — less chance of soil caking on and bridging across tines, especially in wet conditions. Flat bar tines are more structurally rigid and resist bending when you're hitting rock. Many heavier-duty models use flat bar for that reason.
For agricultural rock picking on soft-to-medium soils: round or square bar is fine. For demolition and construction work where you're hitting rebar, concrete, and hard aggregate regularly: go flat bar or square bar in a heavier gauge.
Skeleton buckets run 60" to 84" wide for most skid steers. The sweet spot for a mid-size machine (Bobcat S570, Case SR270, New Holland L230) is 72". That matches the machine's footprint without reaching past the tracks or wheels, which matters when you're working close to concrete pads or garden edges where you don't want to knock things over on the pass.
Match weight to your machine's lift capacity. A 72" skeleton bucket in heavy-duty spec weighs around 450–600 lbs depending on manufacturer. Add 2,000 lbs of material and you're looking at real numbers — don't ignore your machine's rated operating capacity. Virnig V50 models are built for higher-flow machines and run heavier; V40 models are lighter and suit mid-size machines better.
Where this attachment earns its keep in Canada:
A few options worth knowing for Canadian buyers:
A used skeleton bucket is a low-risk purchase if you know what to check. These things are mechanically simple — no hydraulics, no moving parts. But wear shows up in specific places:
It won't dig cleanly into compacted clay or hardpack. The tines punch in but don't carry material the way a GP bucket does. You're better off loosening the area with a GP bucket first, then coming in with the skeleton bucket to sort. It's also a bad choice for loose fine-grained soils like sand — everything runs out and you end up with an empty bucket after each pass.
And it won't backfill. If you need to move material from A to B without losing any of it, use your GP bucket. The skeleton bucket's value is entirely in the separation step.
New skeleton buckets run $1,200–$2,000 CAD for import/budget units in 72"–78" widths (TMG and similar). Mid-tier Canadian-made or better-quality US brands (HLA, Virnig V40) run $2,500–$3,500. Heavy-duty premium models (Virnig V50, Caterpillar OEM) start around $3,500 and go up from there. Used units in decent condition — good tines, straight, matching quick attach — typically sell $800–$1,800 on Kijiji depending on size and condition.
