I went to buy a new air filter for my Dixon the other day. I went to BOTH local Dixon dealers, who are also B&S dealers... Well, NEITHER of them have ever seen an airfilter like the one on my mower...including the dealer i bought it from! So what i am wondering... did they change their design of the 20 HP engines about June, so that it wouldnt be in the partsbook? It is a 20 HP Extended Live series twin cyl. It REALLY p***** me off to buy a new mower that I cant even get an air filter for. I was worried about parts availability when Husq. bought Dixon... well, it aint Dixon parts i need, it is B&S!
