Attachment Fit Checker: Will This Attachment Fit My Machine?

Pick your skid steer, compact track loader, mini skid steer, tractor, forklift, telehandler or excavator and see which attachments in our catalog fit it — checked against the manufacturers' specifications for coupler, hydraulic flow, capacity, carriage class, fork pockets and pins.

How the Fit Checker works

  1. Pick your machineSkid steer, CTL, mini skid steer, compact tractor, forklift, telehandler or excavator. 511 models are pre-loaded with specs from the manufacturers' spec sheets — or enter your own.
  2. Check the specsWe pre-fill capacity, hydraulic flow, coupler and fork data for listed models. Check them against your data plate and correct anything that differs.
  3. See what fitsEvery attachment in our catalog with published fit data is checked against your machine and grouped by category, with current prices.
  4. We confirm the rest“Let's confirm” means one detail is missing or close to a limit. Send it to us — the fit check is free and done before you order.

What we check

Machine type and couplerUniversal skid steer quick attach, mini skid steer couplers (Toro Dingo-style vs Bobcat MT), telehandler quick-attach systems, tractor 3-point hitch category and loader coupler.
Hydraulic flow and pressureThe attachment's required GPM range (and PSI where the manufacturer lists it) vs your machine's standard or high-flow auxiliary circuit.
Lift capacityAttachment weight and rated load vs your skid steer's rated operating capacity or your forklift's capacity at its load center.
Forklift carriage classITA (ISO 2328) carriage class I–IV for hook-on forks and carriage-mounted attachments, plus carriage width.
Fork pocketsFork-pocket and fork-sleeve size of slip-on attachments (hoppers, booms, platforms) vs your fork width, thickness and length.
Excavator size and pinsOperating-weight class of excavator buckets, thumbs and couplers; for pin-on attachments, pin diameter, ear width and pin centers.

Pick-up dimensions for the standard bucket linkage, quoted from Rhinox product pages (attachment manufacturer) and Takeuchi's excavator attachment mount chart; operating weights from the machine manufacturers' spec sheets. Dimensions can change between model versions and with a quick coupler — measure pin diameter (A), the inside width between the bucket ears (B) and the distance between pin centers (C) on your machine, or send us your serial number and we confirm it.

Forklift carriage classes (ITA / ISO 2328)

Carriage classTruck capacity (ISO 2328)Same in lb (converted)Carriage height
Class Iup to 999 kgup to 2,202 lb331 mm (13")
Class II1,000–2,500 kg2,205–5,512 lb407 mm (16")
Class III2,501–4,999 kg5,514–11,021 lb508 mm (20")
Class IV5,000–8,000 kg11,023–17,637 lb635 mm (25")

Capacity ranges and carriage heights from ISO 2328:2011, Table 2 (standard preview); the inch heights match US fork maker MSI Forks (13", 16", 20", 25"). Pound ranges published by fork and carriage makers differ slightly — your truck's data plate and the carriage height decide. Hook-on forks and carriage-mounted attachments must match your carriage class.

Attachment compatibility FAQ

Are all skid steer attachments universal?

Most skid steer attachments sold in North America use the universal skid steer quick attach plate. The ISO 24410 standard “provides for the interchangeability of attachments on skid steer loaders” (ISO 24410:2020), but it also notes that skid steers “can use other styles of quick couplers” that are not interchangeable, and that small skid steers can need a different width. The plate is only the first check: the attachment also has to match your auxiliary hydraulic flow and your machine's rated operating capacity. Pick your machine above and the Fit Checker checks all three.

What GPM is high flow on a skid steer?

It varies by make and model. CASE puts standard flow at 17 to 24 gpm and high flow at 30 to 38 gpm (CASE). Across the 99 skid steers and compact track loaders in our Fit Checker database (manufacturer spec sheets for Bobcat, Case, Caterpillar, John Deere, Kubota, New Holland, Takeuchi), standard auxiliary flow ranges from 8.9–25 gpm and high flow from 26–45 gpm on the 81 models that offer it. Check your machine's spec sheet or data plate.

What skid steer attachments need high flow hydraulics?

Attachments with a hydraulic motor need the flow range their manufacturer lists. For example, Star Industries lists 16–26 gpm for its 72" skid steer brush cutter and 20–30 gpm for its skid steer trencher, while Loflin Fabrication offers its skid steer brush cutters with motors matched to flow ranges from 12–17 gpm up to 35–43 gpm. CASE notes that a standard-flow machine cannot adequately run attachments built for high flow. Plain buckets and pallet forks need no auxiliary hydraulics at all. The Fit Checker compares each attachment's GPM range with your machine.

Are mini skid steer attachments universal?

Not all of them. Most mini skid steer attachments use the Mini Universal plate, which attachment retailer Skid Steer Solutions lists for Ditch Witch, Vermeer, Toro Dingo and Boxer machines. Bobcat offers its MT100 with either the Bob-Tach or the common industry interface (Bobcat), and small Bobcat cab models use a Bobcat MT plate. Choose the quick-tach style in the Fit Checker and we match the plate.

Can you use skid steer attachments on a tractor?

Yes, if the tractor's front loader has a skid steer quick attach coupler or you fit an adapter such as the Loflin tractor to skid steer quick attach adapter. The attachment's weight and load then have to suit the tractor loader's lift capacity. In the Fit Checker choose “Compact tractor” and the loader coupler you have.

What forklift carriage class do I need?

The class follows your forklift's rated capacity. Under ISO 2328, Class II covers trucks of 1,000–2,500 kg (about 2,200–5,500 lb) with a 407 mm (16") carriage, and Class III covers 2,501–4,999 kg (about 5,500–11,000 lb) with a 508 mm (20") carriage — see the table above. Check your truck's data plate or measure the carriage height. Hook-on forks and carriage-mounted attachments must match the class.

How do I measure excavator bucket pins?

Excavator buckets are not universal. As attachment maker Rhinox explains, you need three dimensions: pin diameter, pin centers and the dipper gap (the width between the bucket ears). Measure them on your current bucket or stick, or send us your excavator's model and serial number. The table above shows examples from manufacturers' charts.

Are telehandler attachments interchangeable between brands?

Usually not. The 39 telehandlers in our database use about ten different quick-attach systems — for example the JLG/SkyTrak/Lull common coupler, Genie Quick-Attach, Cat IT, JCB toolcarrier and Gehl Dynattach. JLG's SkyTrak manual also requires that an attachment is approved for the model and matches its capacity chart (JLG). Choose your telehandler in the Fit Checker and we'll confirm the coupler with you.

Not sure? Ask us

Call (307) 441-5529, chat with us, or send a message with your machine's make, model and serial number — we'll check the attachment against the manufacturer's specs before you order.
