Table Saws and Dado blades

I am very new to woodworking. I want to buy a table saw that I can use to make dado cuts. However, I have heard that some saws cannot have dado blades installed in them. Is this true? And if so, how do I know which saws will take a dado blade set?
I'm hoping to buy the saw used to save a bit of money, so I figure I should know about the dado blade capability going into the purchase.
Thanks!

Some have shorter arbors on them. They can still be used but you might have to make multiple pass depending on the size of dado you want to make.

my thoughts would be that most job site saws (table top, light, no legs) may be underpowered and lack the stability to be running a full stack 3/4" dado set. if you can swing at least a contractor style saw, i would go that route....

You'll just have to check with each manufacturer to see which ones might.

@Rebelwork is right. Check with the manufacturer, or find the manual online. It is the only way to know for sure.

It is true that some jobsite saws cannot use a dado stack, period. Other jobsite saws are limited in how wide the dado stack can be. Yet other jobsite saws require a special accessory to use a dado stack wider than certain width. Bosch REAXX and 4100 saws (good jobsite saws) require special accessories for dado stacks wider than 1/2 inch.

Some table saws restrict you to dado stacks only; no wobble dados.

Most (all?) table saws with cast iron tables can take a dado stack up to 13/16 inch wide. Unless you are very tight on space or plan to move the saw from site to site, I would recommend buying a table saw with a cast iron top - a contractor, hybrid, or cabinet saw. They are common on the used market. Any of them should be able to handle a typical dado stack, but check the manual to be sure.

You don't see used SawStop saws very often. All SawStop saws can use dado stacks (not wobble) up to 13/16 inch. You must buy a special dado brake cartridge. The dado stack must be 8 inches and use chippers with wings, which is the most common type. (Some dado stack chippers have solid bodies instead of wings.)

I own an older Bosch job site 10" saw that will accept 13/16" wide dado sets. It is not in current production, but a used one would still be a good deal if priced reasonably:

Here's their latest and cheapest version and it will also, but it's limited to 1/2" wide:
https://www.homedepot.com/p/Bosch-15...1031/202716940


That was one of the questions asked below the product description which did not have the answer....


This is the newest version that is comparable to mine and it also accepts them, BUT does not state a width limitation:
https://www.lowes.com/pd/Bosch-10-in...E&gclsrc=aw.ds

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

my Bosch 4100RT manual says

Quote: For wider cuts (up to 13/16” maximum), chipper blades and
spacers can be placed only between the outside blades
(cutters).
EndQuote

sound like I can go up to 13/16" ??

BUT - my saw is actually a 4100 and looking at it just now it sees that any stack wider than 1/2" will not fit dirctly (as stated in a prior post)

UPDATE:
Got the correct manual and read it. It appears that a thinner outer blade retaining washer is used for thicker dado stacks, instead of the standard (thicker) blade retaining washer.
