Fork attachment coupler type
Select which type of coupler your machine has:
- For the majority of owners your machine will be UQA or Universal Quick Attach
Bobcat invented this hook up style decades ago and it has become the standard globally for compact machinery, skid steers and track loaders, compact tractors, telehandlers and other, for connecting the machine to various attachments, buckets, etc, including pallet forks. Bobcat calls it "Bobtach", everyone else calls it Universal or UQA. Compact loaders made by companies such as Caterpillar, Case, John Deere and many others use this type
- But there are others as well: skid steers that are older (pre-1995) or the littlest ones - the mini skid steers or mini tracked loaders
These will use either their own unique coupler, a smaller scale version, or no quick attach at all, but pin-on connection. See below for more info
If you are unsure of the 5 options above, use the information that follows on this page to determine what kind of coupler style your machine uses, then select the correct one to see what we have to offer that wil fit you machine on the pages to follow.

Universal
Also called UQA or Universal Quick attach, or Bobtach
Bobcat, Caterpillar, Case, John Deere, New Holland, Kubota, JCB, ASV, Terex, Takeuchi, Komatsu, and others
This is the attachment style that nearly all makes of skid steers, compact track loaders and even many compact tractors and zoom-booms or telehandlers and such are using currently. Has been popular since the mid-1990's for almost all makes, globally. So if you have a full size machine (4, 5 or 6 foot or greater in bucket/machine width) and made since 1996, it almost certainly has this connection style. Makes such as Bobcat, Caterpillar, Case, John Deere, New Holland, Kubota, JCB, ASV, Terex, Takeuchi, Komatsu, Thomas, ScatTrak, and others, have been using UQA quick attach compatible couplers for decades.
If unsure check with your manufacturer, dealer, manual or google it. See dimensions below. You will see 2 levers that push 2 pins down through the bottom of the attachment, and the top of the attaching plate catches on an angled top rail of your attachments, see pictures below.
These forks come in a wide variety of weight capacities (we stock 900 through 5500 lb ones, but even heavier can be ordered, to about 10,000 lbs) and fork tine lengths (common are 42" and 48", but longer can be special ordered, 60", 72" etc)

Bobcat MT / S70
These are specifically meant to fit Bobcat-made mini track loaders and their smallest tire skid steers
Bobcat models: 463, S70, MT50, MT52, MT55, MT85, MT100, exclusively
This attachment style is only made to work on the above list of Bobcat brand mini skid steers (wheeled, rubber-tire-equipped) and mini track loaders (MT). We are not aware of any other makes or models that share the use of this attachment type.
It should be noted as well that Bobcat is now producing their MT line (specifically MT100) with the option of using the CID or Mini-Universal attachment hook up type (see next, below), so be aware that you should verify which yours has before you buy.
Looks-wise and dimensionally these are very similar to Bobcat's bobtach (or UQA), full size, as noted above, only narrower. The 2 levers and and coupler plate looks the same, the pin spacing is the same (the pins that push down through the lower holes), they are the same distance apart (about 34" on centre); really the only difference is the overall width of the MT coupler is narrower by about 10" (36" across the whole plate versus the full size one at 45" across), and for this reason there are some ocassions where there is limited cross-compatibility between the full size UQA and the MT couplers and attachments, though using one for the other type would never be recommended.
These forks come in a few options when it comes to weight capacities (we stock 900 lb, 1200 lb and 2000 lb rated capacity units) and fork tine lengths (recommended for this pallet fork type are 36", 42", and 48").

Mini-Universal
Also called Common Interface Connection or CID. There seems to be no universally accepted name for this type yet, so it seems they are referred to by a number of names to this point unfortunately.
Toro-Dingo, Ditch Witch, Vermeer, Boxer, Ramrod, Thomas (mini's), Kanga, and Chinese brands (there are many)
This attachment style is produced only for use on mini track loaders (and some rubber tired units as well), that are not Bobcat made, everyone else in the mini business uses this style.
(Here's the complication to that rule though: Bobcat is now also offering this style on some of their MT-mini-track loader units as an option, so be observant to that possibility if you own a Bobcat MT100 for instance. The 2 types are quite obviously different however.)

North American / European and Japanese/Korean makes such as the following use this coupler style almost exclusively: Toro-Dingo (USA), Ditch Witch (US), Vermeer, Boxer, Ramrod (Canada), Thomas (mini's, Canada), Kanga, and a crop of daily growing manufacturers and brands of equipment coming out of China (cannot cover the list here, but safe to say if you have a mini unit from China, it is of this style), etc. Rule of thumb - if its mini and not Bobcat, its almost for sure this. Check with your manufacturer (dealer, manual) to be sure, and see the dimensions and examples here. The Bobcat MT style is quite visibly different from this CID type.
These forks come in a few options when it comes to weight capacities (we stock 900 lb, 1200 lb and 2000 lb rated capacity units) and fork tine lengths (recommended for this pallet fork type are 36", 42", and 48").

Non-Standard / Proprietary
Anything that is a quick connect style but not one of the 3 above is what falls in this category, considered Non-standard or Proprietary. They are still "quick connect" but just not compatible with any one else's machines.
Anything that is a quick connect style but not one of the 3 above is what falls in this category, considered Non-standard or Proprietary. They are still "quick connect" but just not compatible with any one else's machines.
Currently, some ASV/Terex models, and previously many John Deere, New Holland, Case and Thomas models, perhaps others as well; and ALO/Euro/Quicke we have in this category.
This attachment category applies to a random group of coupler styles that is or was produced for one of 2 main reasons: either it was a matter of patent and timing, or an intentional engineering decision.
These are still considered "quick connect" insofar as they do not require the user to pull out coupling pins (or bang them out with a hammer) to connect and disconnect an attachment, but rather levers are used to quickly do this, like the other common types of quick connect couplers described above. However the design and dimensions are unique to that particular make and possibly even a particular model or models of that manufacturer, and likely only for a limited number of years. And as well these are completely incompatible with any one else's machines. Hence Non-standard, and Proprietary.
The first one - timing/patent: The machines that use a non-standard coupler are older, produced at a time before the Universal / UQA became pervasive across the industry globally (and that was mainly because Bobcat had the patent on it, on their "Bobtach" until about 1996, which prevented other manufacturers from adopting the style and producing machines that utilized it, so those had to resort to making similar variations on the idea but not the same exact design or dimensions, hence incompatible with it); manufacturers who produced skid steers in the late 80s through mid-90's with a quick attach coupler of their own design included names like John Deere, New Holland, Case and Thomas, and perhaps others as well.

The other main reason some models even since 1996 (in fact produced currently) have a unique connection style is due to their own engineering considerations; you'd have to ask them directly for their reasons for doing so - but the most outstanding example of this would be ASV (and for a time branded as Terex in the early 2010's, now called ASV again), and only on their smallest models, notably units with 30 in their model name (such as RC30, PT30, RT30, and also a couple others - the RT25, RT40, and may be others); so while this unique ASV coupler looks very close to the Bobcat MT/S70 visually, when trying to interconnect between makes you'll readily see the dimensions are different. Curiously, even Bobcat made a few models that were unique and not like anything they made or anyone else did either - for the 443 and 453, a single lever quick attach coupler.
A 3rd type we will add to this category only because for our purposes here it fits well, is not particularly popular with skid steers but is very frequently used in larger loaders and bigger tractors, that design is called by a few names, ALO, Euro or Quicke. We mention this because it does exist out there and we can order attachments including forks with this type if one wants, just message us.

Pin-On / Non-Quick-Attach
Quite simply, if your machine does not have levers to lock your bucket or other attachments to it it then it is Pin-On, or Non-Quick Attach.
Quite simply, if your machine does not have levers to lock your bucket or other attachments to it it then it is Pin-On, or Non-Quick Attach.
Currently, no skid steers or tracked loaders that we are aware of are being produced with no lever-operated quick attach mechanism, but pinned on. The most recent popular model that was like this was the Case 1825B which ceased production in 2002.
This attachment category applies mainly to older machines, likely built before 1990. If your bucket or other attachments connect to your machine's tilt and lift cylinders directly with pins (or with an intermediary plate similar to a coupler, but with manual pins), and these pins must be pulled in and out manually (or hammered out and in) and not with levers (which are much quicker) then you have a Pin-On style connection. Few modern machines are made this way, but this was common in 70's and 80's, and in some rare case into the early 2000's.
In most cases we can still order buckets and forks that will work with your model, as it is now, with pins (special order), at a surprisingly comparable price. Alternatively, if you are still wanting to keep your machine and not upgrade it to a more recent one but would like the convenience of a modern machine's being equipped with a typical quick attach with levers, there are quick-attach conversion couplers available for most of these older machines, which can be ordered and we can get i for you. Inquire, click here.

Not related to the topic of connection types particularly, but if you are looking for used forks or power-operated ones click the links below. Both are available in nearly any connection type (ie of ones shown above). In the case of used, it obviously depends on what happens to come in. When it comes to specially-purposed hydraulically powered adjustable forks, those can be ordered (new) with nearly any type of quick attach (or even pin-on) connection to match your machine.
