If you already have a pin-on bucket… the most-common advice is to go to a SSQA adapator and buy SSQA implements from now on.
This has some downsides not often noticed: The SSQA modification is heavy and reduces lift-capacity of the loader. It is not an inexpensive modification…
It also requires changing the method of attachment of your existing bucket.
If you already have other implements it means you must also either discard them…or modify them to the SSQA system also…in every case adding weight (reducing capacity).
Obviously, any purchases of addt’l implements must be SSQA style.
There is another method. You can obtain pin-on adaptors which will mate with other pin-on implements…AND …can also use a SSQA adaptor …(should you need to use both types of equipment.)
I acquired mine form
danannah@gmail.com Cost was about $400 and virtually no deduction in lifting capacity.
He’s in Canada and made mine and shipped them very quickly. (and my M4700 was an odd size.)
