OK it's new left over late model, it has a 25hp Kolher 60" deck, the Kolher doesn't have a canister filter and the fuel tanks have really small caps. I wish I had thought to get the #'s off it but I didn't. Anyways, what model would you guess it is and how much would you pay for it. Again it's brand new, just a late model. Oh how much to add the canister filter?
