Before you buy a used attachment off Kijiji — or before you buy your next machine — you need to understand which brands use universal SSQA and which use proprietary systems that lock you into a narrower attachment market. The difference can cost thousands of dollars over a machine's lifetime. This guide covers every major brand in the Canadian market.
SSQA stands for Standard Skid Steer Quick Attach. It's based on SAE J2513, the engineering standard for skid steer loader mounting interfaces. The geometry: a pair of top hooks that engage a cross-bar on the attachment plate, combined with a bottom latch mechanism that locks the plate in place once the hooks are seated. Simple, robust, and — critically — standardized across manufacturers who chose to adopt it.
The standard didn't emerge from a neutral committee dreaming up the ideal coupler. It was largely derived from Bobcat's proprietary Bob-Tach design, which was so dominant in the market that the industry essentially standardized around Bobcat's geometry. This is why "SSQA" and "Bob-Tach compatible" are sometimes used interchangeably — they share the same basic geometry on full-size current machines.
But the important distinction is this: manufacturers who use "universal SSQA" explicitly design and certify their machines to the open standard. They sell against it, they publish compatibility specs for it, and they support third-party attachments on their machines. That's meaningfully different from a manufacturer who uses a compatible-but-branded system and steers customers toward proprietary products at every opportunity.
| Brand | System Name | SSQA Compatible? | Proprietary Lock-in Risk | Notes |
|---|---|---|---|---|
| Bobcat | Bob-Tach | MOSTLY YES | Medium-High | Compatible in practice on current full-size machines; Bobcat doesn't certify third-party use; smaller/older models are genuinely incompatible |
| Cat (Caterpillar) | Cat BOCE / Universal | YES | Low | Current Cat machines (246D, 262D, 289D, 272D, 299D series) use SSQA-compatible interface; some older pin-on models predated universal coupler |
| Case | Power-A-Tach / Universal | YES | Low | Case machines (SR series, SV series, TV series) use universal SSQA; Power-A-Tach hydraulic attachment option is proprietary but mechanical interface is standard |
| Kubota | SSL (Super Skid Steer Loader) | YES | Low | All current SSV and SVL machines use SSQA-compatible SSL interface; third-party attachments mount without adapters |
| New Holland | SSQA (no brand name) | YES | Very Low | Every 200 Series machine (L218–C238) uses standard SSQA; the most attachment-open mainstream brand in Canada |
| John Deere | QuikTatch / Worksite Pro | MOSTLY YES | Medium | Current JD skid steers (310, 320, 330, 332) are SSQA compatible; Worksite Pro attachment line works on SSQA; some JD product listings are confusing about compatibility |
| Gehl | SSQA | YES | Very Low | Gehl (now part of Manitou Group) uses universal SSQA throughout; strong open compatibility record |
| Mustang / Manitou | SSQA | YES | Very Low | Mustang and Manitou machines use universal SSQA; less common in Canadian market but fully open attachment ecosystem |
| ASV | SSQA | YES | Low | ASV (Canadian-connected brand, built in Grand Rapids, MN) uses SSQA throughout; RT series machines are popular in soft-ground and forestry applications |
| Takeuchi | SSQA (TL series CTLs) | YES | Low | Takeuchi track loaders use SSQA; less wheeled skid steer presence in Canada but their CTLs are SSQA compatible |
| Terex (older) | SSQA (varies by year) | VERIFY | Medium | Terex skid steers are out of production; if you're buying a used Terex, verify the coupler format on that specific machine before ordering attachments |
Bob-Tach is the original from which SSQA was derived. Current full-size Bobcats (S450 and up, T450 and up) have plate geometry that overlaps with SSQA closely enough that most SSQA attachments mount without adapters — but Bobcat doesn't certify or officially support this. They market their own attachment line aggressively.
Where it breaks down: the S70 small skid steer and all MT-series mini skid steers use narrower coupler profiles that are not SSQA compatible. Older pre-2000 Bobcats may also have variations. The older 600-series machines (753, 773) need individual verification.
Current Cat skid steers and compact track loaders (246D, 262D, 272D, 289D, 299D, 320D2 series) use the universal SSQA interface. Cat's own Werk-Brau and Cat-branded attachments are SSQA format. Any third-party SSQA attachment mounts directly.
The older pin-on Cat machines (pre-coupler era, some early 236, 246 models) required pin-mounted attachments — no quick coupler. If you're looking at an old Cat, confirm the boom end has a coupler receiver, not bare pins.
Case skid steers (SR130–SR270, SV185–SV340, compact track loaders TV380–TV450) use universal SSQA as their standard mechanical interface. Every SSQA attachment mounts.
The "Power-A-Tach" name refers to Case's optional hydraulic attachment locking mechanism — a cab-operated system that locks and unlocks the coupler without the operator exiting. This is a machine-side feature only; it doesn't affect attachment compatibility. An attachment that fits a Case without Power-A-Tach also fits one with it.
Kubota's "SSL" designation is their branding for what is functionally the SSQA standard coupler on their SSV and SVL machines. SSV65, SSV75, SVL75-3, SVL97-2 — all SSQA compatible. No adapter required for any standard third-party attachment.
Kubota sells their own branded attachments through the dealer network at OEM pricing, but they can't prevent third-party attachment use and there's no functional lock-in. The attachment fit is clean and tested.
New Holland doesn't even give their coupler a brand name — they just call it SSQA. Every 200 Series machine (L218 through C238) ships with the universal standard. No attachment ecosystem marketing, no proprietary lock-in angle, no upsell path to branded attachments. Buy whatever fits and runs the right hydraulics.
This is the most straightforward attachment situation of any mainstream machine in the Canadian market. If someone lists a universal SSQA attachment on Kijiji, it mounts on an NH. That's the full story.
Current John Deere skid steers and compact track loaders (310G, 320G, 330G, 332G, CT322, CT332, 325G, 331G series) use an SSQA-compatible interface. John Deere calls their system "QuikTatch" and their attachment brand "Worksite Pro," but the underlying geometry matches SSQA.
The gotcha with John Deere: some Worksite Pro attachments list exclusively as "John Deere compatible" rather than "universal SSQA" in their product specs, which can create confusion. If you're buying a third-party SSQA attachment for a JD machine, it should fit. But check the attachment's listed compatibility — some smaller suppliers list machines by brand rather than standard.
Gehl skid steers and compact track loaders have used universal SSQA consistently. The company is now part of Manitou Group (same parent as Manitou telehandlers and Mustang machines). Gehl machines are less common in Canada than Bobcat or Kubota, but you'll see them in Ontario and Quebec markets.
Any SSQA attachment mounts on a Gehl. No caveats. The machines themselves are decent — the 4640E and 5640E track loaders are sometimes available used at good prices because Gehl doesn't have Bobcat's brand premium in Canada.
Manitou skid steers and Mustang machines (same corporate family as Gehl) use universal SSQA. If you encounter a Mustang skid steer or compact track loader at auction — they show up occasionally at Ritchie Bros. — it will accept standard SSQA attachments.
These are not common enough in Canada to build an attachment collection around, but if you buy one (usually at a discount vs the name-brand machines), you're not stuck for attachments.
This is the practical part. You've found a grapple on Kijiji in Red Deer or an auger at a Ritchie Bros. sale in Nisku. The listing says "universal skid steer." How do you actually know it fits your machine?
Ritchie Bros. unreserved auctions (Nisku, AB is the largest western Canada location; Innisfil, ON for eastern Canada) regularly sell skid steer attachments. A few realities:
"Universal" doesn't always mean SSQA. Some sellers list mini skid steer attachments as "universal" when they're actually the smaller mini-format. And some older attachments were built for machines that predate quick couplers entirely — they have pin-on receiver configurations that fit nothing with a standard SSQA.
If the price is suspiciously low for the size, ask questions before driving. A 72" GP bucket for $200 is either very worn or the wrong coupler format for your machine. Usually both.
Adapter plates solve specific mismatch problems. They're not a universal fix, and they come with genuine trade-offs worth understanding.
Adapter plates add a connection point between machine and attachment. That connection can fail. Here's where the genuine risk lives, and here's where it's overstated:
Real risks:
Overstated risks:
When buying a machine, especially a first machine or an addition to a fleet, quick attach compatibility deserves explicit weight in the decision. Not the only factor. But a real one.
Situations where it matters most:
Situations where it matters less:
New Holland, Kubota, Case, Cat, Gehl, and ASV use true universal SSQA. Buy any attachment, it fits. No asterisks.
Bobcat and John Deere use SSQA-compatible systems on current full-size machines — works in practice, both companies lean into proprietary attachment marketing. Be an informed buyer.
Mini skid steers (Bobcat MT, Toro, Dingo, Vermeer S-series) are a completely separate attachment ecosystem — do not mix up mini and full-size attachments.
Adapter plates solve specific mismatch problems. Buy quality ones. Inspect them. Know the weight penalty. Understand the certification gap before using them on regulated worksites.
When buying used attachments on Kijiji or at auction: ask what machine it came off, look at the mounting plate, and measure if you're unsure. The price of a wrong assumption is a drive back to return something that won't fit.
