String Trimmers

I have a 128CD weed wacker. Just bought it brand new, but the fellow at the store could not tell me which accessories fit, or where to buy them.

Can you tell me if Brushcutter attachment BCA 850/24 will fit this model?

If there is nothing with Husqvarna brand on it, can you tell me which 3rd party company makes a good brush cutter that will attach?

Thank you, Bjarki
