I'm sure it can be done. You need to measure your blades themselves to cross reference them.
However, a power rake really doesn't do anything good for anyone. I have tried them out before and they either do nothing or they destroy the lawn. Perhaps other people have had greater success than me with a power rake. If you are thinking about dethatching your lawn with them, I'm sure you could do it, but it may just do more harm than good. Buy or rent a thatcher that you can tow behind your tractor.
