Bucket width is the #1 sizing question for new buyers — and getting it wrong means either leaving material on the edges or being too wide for your job site. Here's how to match width to your machine, job, and site.
Most first-time buyers just order the same size bucket their dealer had in stock. Sometimes that's right. Often it isn't. The wrong bucket width leaves material piling up on the sides of your machine, or worse — gets you stuck at a gate that's 8 inches narrower than your bucket.
Bucket sizing has a real formula behind it. Here's how to apply it.
Bucket width should be 110–120% of your machine's track width (measured outside tread to outside tread). This gives you enough overlap to clean up alongside the machine on each pass without being so wide that material piles up beyond your tracks.
Best for compact machines and tight residential sites.
The universal size. Most available, fastest delivery.
Best for open sites, production grading, large material moves.
| Machine Model | Track/Tire Width (outside) | Ideal Bucket Width | Notes |
|---|---|---|---|
| Bobcat S450, S510 | ~62–66" | 66–72" | 66" for tight sites; 72" if you want max coverage |
| Bobcat S530, S550 | ~67–68" | 72" | 72" is the natural match; 84" possible on open sites |
| Bobcat S570, S590 | ~68–72" | 72–84" | 84" suits open commercial work; 72" for residential |
| JD 318G | ~64" | 66–72" | Similar to Bobcat S450 class |
| JD 326G, 328G | ~68" | 72–78" | 72" is the standard; 84" for production grading |
| JD 332G | ~72" | 78–84" | 84" is the right size for this machine class |
| Case SR210, SR240 | ~67–69" | 72" | 72" standard; confirm site access before going 84" |
| Case SR270, SV340 | ~72–76" | 80–84" | 84" appropriate for these heavier machines |
| Kubota SSV75, SVL75 | ~65–72" | 72–78" | 72" is conservative and widely available |
A 66" bucket on a machine with a 68–72" track width is narrower than the machine itself. Every pass leaves a ridge of material on the outside edges of your tracks. You're doing extra passes where the machine already has to maneuver. On grading work especially, this is frustrating — you spend more time cleaning up edges than you should.
The 66" is genuinely the right choice for compact machines (where track width is 60–66") and for tight residential sites where gate clearance matters (residential gates are typically 48–60" wide — any bucket size will need to angle for these). But on a mid-frame machine, the 66" leaves performance on the table.
The 72" bucket is the most stocked size at Canadian dealers by a significant margin. This means:
For a mid-frame machine doing mixed residential and light commercial work, the 72" is usually the right answer. It doesn't underperform on the machine, it clears most access points, and it's the easiest to source and maintain.
The 84" bucket pays off when your work is predominantly open-site production: large grading jobs, commercial site prep, material moving on rural properties. Each pass covers more ground. Fewer passes means faster job completion. At 450–700 lbs (depending on brand and steel gauge), the 84" is also the heaviest option — verify against your machine's rated operating capacity before ordering.
The gate problem: Most residential properties have gates in the 48–60" range. An 84" bucket does not fit through a 60" gate. If you're doing residential work, this is a practical constraint that often eliminates the 84" regardless of machine size. Measure the narrowest access on your typical jobs before ordering.
This is the second most common bucket question. The choice comes down to what you're cutting into:
| Flat Cutting Edge | Teeth / Tooth Bar | |
|---|---|---|
| Best for | Grading, spreading, surface work, soft to medium soil | Hard ground, clay, rocky soil, breaking frost |
| Surface finish | Clean, smooth — good for finish grading | Rough, ripped — not for final grade |
| Material penetration | Moderate — slides under soil | High — teeth bite and break |
| Typical use | Topsoil, gravel, mulch, sand, backfill | Breaking hardpan, digging in clay, frozen ground |
| Reversible? | Yes — most cutting edges are reversible (flip for fresh edge) | Teeth are bolt-on; tooth bar mounts over cutting edge |
Recommendation: Buy the bucket with a flat cutting edge first. A bolt-on tooth bar can be added for $150–$350 CAD when hard ground work demands it. The cutting edge handles the majority of landscaping and construction tasks — and gives you a clean surface finish that teeth never will.
Attachment weight directly affects your machine's rated operating capacity (ROC) and tipping load. Exceeding ROC is unsafe and can damage your machine. Approximate bucket weights:
On a compact SSL with 1,000 lb ROC, a 500 lb bucket leaves you 500 lbs of rated payload. Check your machine specs. Heavy-duty buckets (thicker steel, full-bar reinforcing) are heavier but last longer — the right choice for production work, potentially overkill for light residential use.
All three sizes (66", 72", 84") are available from the following brands through Canadian dealers:
| Job Type / Situation | Recommended Size | Why |
|---|---|---|
| Compact machine (Bobcat S450, JD 318G) | 66" | Matches track width; oversized bucket is counterproductive |
| Mid-frame machine, residential work | 72" | Gate-friendly, widely available, correct coverage for machine |
| Mid-frame machine, open commercial sites | 72–84" | 84" if no gate constraints; more material per cycle |
| Gravel driveways and residential properties | 72" | Gate access; sufficient coverage; most versatile |
| Large-frame machine (Bobcat S770, Case SV340) | 84" | Machine ROC supports heavier bucket; track width demands it |
| Production grading, farm or commercial | 84" | Maximum material per cycle; faster site completion |
| Tight urban or residential lots | 66–72" | Maneuverability over capacity |
| Unsure — want maximum flexibility | 72" | Best availability, most versatile, easiest to resell |
If you're on a mid-frame skid steer and aren't sure, order the 72". It's the most available size in Canada, fits the widest range of machines, and handles the majority of jobs without the access constraints of the 84". Add a tooth bar if your ground is hard. Buy the 84" when your work is primarily open-site and production speed matters more than gate clearance.
