The bucket is the first attachment on most skid steers and the one that gets used the most. It's also the one people size wrong, order with the wrong cutting edge, and outload their machine with. Here's how to get it right the first time.
A bucket sounds like the simplest possible skid steer attachment. It's not. Walk through any equipment dealer lot and you'll find at least six different bucket types, three cutting edge options, and widths ranging from 60 to 96 inches. The wrong combination for your machine and your work ends up either costing you productivity or getting you into trouble when the bucket is full of wet clay and your machine can't lift it.
This guide covers the decisions that actually matter: which bucket type, which width, which cutting edge, and whether a 4-in-1 is worth the premium for your situation.
The most common bucket on skid steers in Canada. A GP bucket has a solid back and floor with a straight or lightly curved cutting edge, designed for moving loose to moderately dense material: topsoil, gravel, sand, fill dirt, mulch, and light demolition debris. It's the bucket that comes standard with most new machine purchases and what most rental yards have on their fleet. If you're only ever going to own one bucket, this is the one.
A GP bucket with beefier steel — thicker floor, reinforced side plates, heavier cutting edge mounting. Built for quarry work, blasted rock, rip-rap, and dense aggregate. The extra weight is real: a heavy-duty 72" rock bucket can weigh 200–300 lbs more than its GP equivalent. If your machine is already close to its rated operating capacity with your normal loads, that extra bucket weight eats into your usable payload. Rock buckets are the right call for operators running in hard aggregate or demolition applications regularly — not for the occasional gravel job.
Has bars or tubes instead of a solid floor. Material falls through the gaps; rocks and debris stay in the bucket. Used for separating rock from topsoil, cleaning up demolition sites, and screening fill. The screening gap size varies by manufacturer — typically 2" to 4" bar spacing. They're slow and they're specialized: a skeleton bucket screens material well but moves far less volume per cycle than a solid bucket. Worth having if you're doing site prep work with a lot of rock sorting; not worth it as your only bucket.
A higher-capacity bucket with a taller back and more pronounced curl. Designed for topsoil, mulch, wood chips, snow, and other low-density, high-volume materials. The rated heaping capacity on a light material bucket can be 30–50% higher than a GP bucket of the same width — useful when your limit is volume rather than weight. The trade-off is that the taller profile reduces forward visibility and the thinner steel isn't meant for rocky ground. Landscaping contractors moving topsoil and mulch on clean sites get a lot of value from these; contractors working on rough ground with mixed material don't.
A standard bucket with a clamshell bottom that opens hydraulically. Can function as a standard bucket, a grapple (clamshell closed against load), a dozer blade (laid flat), or a scraper/grader. The appeal is versatility — one attachment that does four jobs. We cover these more thoroughly below.
Rotates hydraulically to dump material to the left or right instead of over the front. Used in trench work where you can't swing the whole machine to dump, or in tight indoor spaces. Less common but genuinely useful in applications like pipeline trench backfill or indoor demolition where the geometry doesn't allow forward dumping. Requires a hydraulic auxiliary circuit on the machine.
The standard rule: bucket width should be 110–120% of your machine's track or tire width. This keeps the bucket clearing the undercarriage footprint and prevents you from digging a channel narrower than your machine's path. Going significantly wider reduces breakout force and puts lateral stress on the coupler; going narrower and you're filling your own tracks.
| Machine Weight Class | Typical Track/Tire Width | Recommended Bucket Width | Common Machine Examples |
|---|---|---|---|
| Small (under 6,000 lb) | 60–66" | 60–66" | Bobcat S450, Cat 239D, Kubota SSV65 |
| Medium (6,000–8,500 lb) | 66–72" | 66–72" | Bobcat S650, JD 324G, Case SV250 |
| Large (8,500–11,000 lb) | 72–78" | 72–78" | Bobcat S770, Cat 272D, JD 332G |
| XL (11,000+ lb) | 78–84" | 78–84" | Bobcat S850, Cat 299D3, JD 344G |
Common available widths from most manufacturers: 60", 66", 72", 78", 84". If you're between sizes, go to the next wider — a bucket slightly wider than optimal is better than one that's too narrow. Always verify your specific machine's undercarriage width from the spec sheet, as wheeled and tracked variants of the same model can differ.
The cutting edge is the consumable part of the bucket. It wears and it's designed to be replaced — but the type you choose determines how the bucket performs in different material.
A flat steel bar across the bucket bottom. Produces a clean, flat cut surface. Good for: finish grading, scraping hard-pack surfaces, loading clean aggregate, working on pavement. The clean edge leaves a smooth floor behind it. Wear is even across the full width. Standard choice for most general grading and loading work.
Individual replaceable teeth bolted to the cutting edge. Penetrate hard and compacted material far more effectively than a straight edge — the point load is much higher than a flat edge. Good for: breaking into hard-packed ground, frozen soil, clay, digging into compacted fill. Downsides: they don't produce a clean finish grade, they're harder on paved surfaces, and the individual teeth need to be replaced as they wear. For Canadian operators doing winter work on frozen ground, teeth on the cutting edge are often essential — a straight edge just skids off frost-hardened soil.
A middle ground between a straight edge and teeth. The serrated profile gives better bite than a flat edge without the individual tooth maintenance of removable teeth. Good for: general digging in mixed material, topsoil, gravel, and moderate clay. Common in Prairie and BC ag work where ground conditions vary. Not quite as aggressive as individual teeth in hard conditions, not quite as clean as a straight edge for finish work.
The cutting edge is made up of bolt-on sections rather than one continuous bar. Allows you to replace only the worn section rather than the full edge. Useful for contractors running buckets hard who want to minimize downtime. Some manufacturers offer interchangeable segments that let you configure straight and toothed sections across the bucket width.
Every bucket has a rated heaping capacity in cubic yards or cubic feet. This is the physical volume the bucket can carry with material heaped above the sides. The number that limits what you can actually lift is your machine's Rated Operating Capacity (ROC) — typically 35–50% of tipping load depending on machine and brand ratings standard (SAE vs. ISO).
The issue: material density. A 72" GP bucket with a 0.6 cubic yard capacity sounds modest, but fill it with wet clay or run gravel and you're looking at a heavy load:
| Material | Approximate Density (lb/yd³) | Weight in 0.6 yd³ Bucket |
|---|---|---|
| Dry topsoil | ~2,000 | ~1,200 lb |
| Moist topsoil | ~2,400 | ~1,440 lb |
| Dry sand | ~2,600 | ~1,560 lb |
| Wet sand | ~3,200 | ~1,920 lb |
| Gravel (dry) | ~2,800 | ~1,680 lb |
| Compacted clay | ~2,700 | ~1,620 lb |
| Blasted rock | ~3,400–4,000 | ~2,040–2,400 lb |
A medium-size skid steer with a 2,000 lb ROC can handle a full bucket of dry topsoil. Load that same bucket with wet sand and you're at 96% of capacity before adding the bucket weight itself. Most operators learn this by feel. The better approach is to know your machine's ROC, know your material, and do the math before you order a high-capacity light-material bucket and try to use it for gravel.
Combination buckets are the most discussed and most misunderstood bucket type. Here's a straight answer: they're excellent tools for the right operator and a mediocre choice for pure-production contractors.
A 4-in-1 costs noticeably more than a standard GP bucket of equivalent size. It requires a functioning auxiliary hydraulic circuit. It's heavier than a standard bucket, which reduces your usable payload. And in any single function mode, it's not as good as a dedicated attachment — it doesn't scoop as cleanly as a GP bucket, doesn't doze as well as a dedicated blade, and doesn't grip as well as a dedicated grapple.
What it does well: it does four jobs with one attachment, which matters a lot if your machine carries one or two attachments at a time and you're doing varied work. For farms and acreages where the skid steer is used for a dozen different tasks — loading feed, dozing a pad, cleaning up brush, scraping the yard — a combination bucket is one of the most practical single purchases you can make. For a contractor whose machine runs one job type all day, it's less compelling.
The open-clam position is also legitimately useful for carrying oversized or irregular material — bales, brush piles, logs — that a standard bucket can't hold. That alone earns its place for many farm operators.
Winter ground conditions: Most of Canada deals with frozen ground from November through March. A straight cutting edge on frozen soil accomplishes almost nothing — the bucket skids along the surface. If you're doing winter work on native soil or compacted frozen ground, teeth on your cutting edge aren't optional. Many Prairie operators keep a spare cutting edge with teeth for winter work and a straight edge for summer grading.
Spring thaw: The mud season in BC, Alberta, Manitoba, and Ontario is hard on equipment and even harder on buckets. Wet, sticky clay sticks to bucket floors and reduces cycle efficiency. Combination buckets with a clamshell action are useful here — the clam opens to release stuck material that would otherwise require manual clearing. Rounded bucket profiles shed material better than squared-off designs.
Prairie topsoil work: Saskatchewan and Manitoba topsoil is productive and valuable — and contractors doing topsoil stripping, stockpiling, and spreading work hard to preserve it. A light-material bucket or a standard GP with a clean straight edge is the right call for final-pass topsoil work. Teeth chew up the stripped layer and mix more subsoil in.
Construction site cleanup: Across Canadian urban centres, mixed-debris cleanup — concrete chunks, rebar, lumber, mud — favours heavy-duty GP buckets with weld-on or bolt-on segment cutting edges. The mixed material hits hard and wears cutting edges fast.
Buckets are made by a lot of manufacturers. Here's a realistic tier map for Canadian buyers:
OEM Premium (Bobcat, John Deere, Caterpillar): Dealer-sourced OEM buckets are engineered to exact machine specs, come with full warranty coverage through the dealer, and are the default recommendation when the machine is also brand new and under warranty. Premium pricing reflects that. If you're outside warranty and sourcing attachments independently, the OEM premium is harder to justify.
Mid-Market (HLA Attachments, Werk-Brau, Skid-Pro, IronBull): HLA is Canadian-made (Ontario) and widely distributed through agricultural and construction dealers across the country. Werk-Brau has a long reputation in heavy-duty buckets. Skid-Pro and IronBull offer good value at mid-market pricing with reasonable parts and service support in Canada. This tier is where most working contractors land.
Budget (TMG Industrial, Chinese-sourced generics): TMG Industrial ships from Canadian warehouses and offers a warranty. The steel quality and weld quality is generally below the mid-market tier, which shows up in high-cycle commercial applications. For occasional-use farm and residential equipment, the value proposition is reasonable. For fleet buyers running machines every day, expect shorter service life.
Three rules that cover most bucket buying decisions:
A 72" GP bucket with teeth on a mid-size CTL covers 80% of what most Canadian contractors need. From there, specific applications push you toward light-material, heavy-duty, combination, or skeleton variants. Know your primary job first, then spec accordingly.
