A bucket is not a bucket. Width, type, edge, and teeth all change what the tool costs to run and how well it handles your specific soil and application. Here's how to sort it out.

Buckets are the attachment most operators already own and the one most commonly misused. A general purpose (GP) bucket pulled through BC rock will wear through its cutting edge in a fraction of the time a proper rock bucket would. A heavy-steel rock bucket doing residential grading in Ontario clay is money wasted on material you don't need. And a 78-inch bucket on a small-frame machine isn't just inefficient — it's actively unstable in some loading scenarios.
Let's go through what actually matters in bucket selection.
Standard construction for dirt, gravel, sand, light soil work, and mixed material. Not designed for consistent rock or blasted material. The right tool for most Canadian landscaping, grading, and general contractor work.
Heavier steel, reinforced cutting edge, often fitted with replaceable teeth. Built for aggregate, rip-rap, blasted rock, and hard-digging conditions. Costs more upfront, but the wear savings in rocky applications are real.
Larger capacity, lighter construction. Designed for low-density material — mulch, snow, wood chips, sawdust. Bigger opening means more volume per cycle, but overload it with heavy aggregate and you'll stress the mounting plate and boom.
This is where a lot of first-time buyers make the wrong call. They size the bucket to the job ("I need to move a lot of gravel, so bigger is better") without checking whether the machine can safely handle the weight at full capacity. A 78-inch wide bucket on a small-frame machine (like a Bobcat S510 or Kubota SSV65) will be overweight at half-load in dense material. The machine tips forward, the lift system works harder than designed, and response time gets sluggish.
Width also affects visibility. On a large bucket on a small machine, the operator's sightlines compress and it becomes harder to place material accurately or see obstacles at the front of the cutting edge.
| Machine Frame Size | Typical ROC Range | Recommended Bucket Width |
|---|---|---|
| Small frame (Bobcat S510, Kubota SSV65 class) | 1,300–1,800 lbs ROC | 60"–66" maximum for dense material |
| Mid frame (Bobcat S650, Case SV280 class) | 2,200–2,800 lbs ROC | 68"–72" standard, 74" in light material |
| Large frame (Bobcat S850, CAT 299 class) | 3,000–4,300 lbs ROC | 72"–84" depending on application |
These are general guidelines, not gospel. Always check your machine's rated operating capacity (usually 50% of the tipping load) against the combined weight of bucket plus expected load. Manufacturers publish this in the spec sheet — if you don't have it, the dealer can pull it for your exact model and year.
Bucket capacity (cubic feet or cubic yards) doesn't scale linearly with width. A wider bucket at the same depth carries more volume. But two buckets of the same width can have very different capacities depending on depth, floor shape, and sidewall height. The common mistake: buying based on width alone and assuming capacity from that.
For comparison: a 72-inch GP bucket might be rated at 0.5–0.6 cubic yards. A 72-inch light material bucket of the same width might be rated at 0.7–0.9 cubic yards because it's deeper. If you're moving mulch or wood chips, the capacity difference is significant over a day of cycles. If you're moving dense gravel, the extra depth becomes dead weight you're lifting with every cycle.
The cutting edge is a wear part. It contacts the ground on every scrape and takes the abrasive load of whatever you're pushing through. Two options:
Bolt-on cutting edges bolt to the bottom of the bucket and can be replaced when worn without welding or heat work. This is the right choice for contractor use — replacement takes an hour, not a fabricator. Most quality buckets come with bolt-on edges standard, or offer them as an upgrade. Replacements cost $80–250 CAD depending on length and material.
Welded cutting edges are integral to the bucket. They're slightly stronger in heavy impact applications (ripping blasted rock, for example) but when they wear down, the bucket needs to go to a shop for rebuilding. Fine for a bucket you'll own long-term with access to a welder, less practical for a rental fleet or contractors who'd rather not deal with downtime.
Side cutters are replaceable steel plates bolted to the outer corners of the bucket. They protect the side corners from abrasion when working close to curbs, walls, or other vertical surfaces that would otherwise cut into the bucket's side panels.
For general grading and loading, skip them — they add cost and occasionally catch on things. For operators doing confined work alongside concrete, stone, or existing structures regularly (utility trenching next to buildings, curb work), they pay for themselves in bucket longevity. Retrofit side cutters are available for most standard buckets.
Teeth are useful for penetrating hardpan, compact aggregate, or clay that a smooth cutting edge would skim over. They concentrate force at the tip and help the bucket dig in.
When you want teeth: Breaking up compacted subgrade, digging into clay or hardpan, rocky digging where you need penetration before scooping, any aggressive digging application.
When you don't want teeth: Finish grading, working on pavement, moving aggregate you want to scrape cleanly, any application where leaving a smooth floor matters. Teeth leave ridges and marks in everything they touch.
Bolt-on replaceable teeth (like Hensley, Tiger, or Esco-style) are the standard for GP and rock buckets. The tooth body is welded or pressed into the bucket base, and the actual tooth (the wear piece) pulls out with a pin and is replaced in minutes. Keep a few spare teeth on the truck — you'll snap one eventually in rocky ground and the job doesn't have to stop.
The question comes up constantly: can I get away with a GP bucket for my gravel driveway installation jobs? The answer is yes — for a while. The real question is how much you're spending replacing or rebuilding that cutting edge versus what a proper rock bucket would cost over the same period.
A GP bucket used in aggregate and angular gravel will wear its cutting edge 2–4x faster than in soft soil. If you're replacing a bolt-on edge twice a season at $150 a replacement vs once a season with a rock bucket and a Hardox edge, the rock bucket's $400–600 premium over the GP pays back within a season or two of regular aggregate work. For occasional gravel use, the GP is fine. For contractors who do gravel driveways, aggregate spreading, or quarry material handling as a regular part of the business, the rock bucket is the right tool.
Prairie black soil is rich and relatively soft when dry. A standard GP bucket is the correct tool here — smooth cutting edge, moderate steel, no teeth needed for most applications. The challenge is early spring when the ground is thawing unevenly — the top 4 inches might be soft while the layer below is still frozen solid. A GP bucket will deflect on that frost line rather than cutting through it.
BC's mix of glacial till and bedrock is where the rock bucket earns its cost difference fastest. Operators using GP buckets in BC rock are buying cutting edges constantly and still wearing sidewalls that weren't designed for that abuse. Specify a rock bucket with a minimum 80-grade Brinell hardness cutting edge. Teeth are mandatory for most BC material work.
This is the other extreme. Northern Ontario and much of Northern Canada has muskeg — deep organic peat that's essentially a saturated sponge. A regular heavy-steel bucket sinks into muskeg on every pass because of its own weight and the material's low bearing strength. Light material or high-flotation bucket designs exist for peat work, and some operators use a wider bucket to spread the force across more surface area. The attachment weight matters as much as anything else in muskeg conditions.
New buckets are available through local equipment dealers (Bobcat, John Deere, Kubota, Case, New Holland) and through Canadian-based steel suppliers and attachment manufacturers. TMG Industrial ships from BC to most provinces and is popular for mid-range GP buckets at competitive pricing. Paladin Attachments and Werk-Brau are available through dealers across Canada and are reliable choices for commercial-grade edges and heavier plate construction.
For anyone doing significant rock or aggregate work, it's worth calling HLA Attachments (Ontario-based manufacturer) or a regional Bobcat/Deere dealer to spec a proper Hardox-edge rock bucket. The difference between a mild steel cutting edge and a Hardox 400/500 edge in abrasive material isn't subtle — Hardox holds a usable edge 4–5x longer in granite aggregate. The premium is real but so is the replacement interval difference.
Used buckets are the easiest attachment category to buy secondhand — they're simple steel, and wear is visible. What to check: cutting edge thickness (a bolt-on edge with less than 30% of original thickness remaining usually isn't worth buying as-is — factor replacement cost into the price), look at the back of the mounting plate at the weld lines for hairline cracks, and confirm the plate coupler matches your machine before driving anywhere. Mismatched Bob-Tach vs SSQA plates are common on used listings and not always disclosed. Kijiji and MachineryTrader Canada both have regular bucket inventory across provinces.
Price benchmarks for used GP buckets in decent condition: 66–72 inch mid-frame buckets run $400–900 CAD depending on edge condition and location. Rock buckets with a good Hardox edge in the same size range fetch $700–1,400. New mid-grade GP buckets (TMG, Titan) run $900–1,500 new; OEM Bobcat and Deere GP buckets are $1,500–2,500+ at dealer pricing.
