Skidsteers have arms that are a bit more stout than loader arms on a tractor. They are the primary & more or less only interface for a SS, but are a poorly placed afterthought on a tractor.
I'm sure you could put a SSQA breaker on a loader with a SSQA mount. Whether you'd have enough hydraulics to run it would be questionable, but less so than whether or not it would be a good idea for the longterm viability of your tractor.
