It's a 2005 Kohler Command CV730 26 HP with about 30 hours and I'm doing the first oil change.... The manual says to use #12-050-01-S. The filter that came on it is a yellow Cub Cadet #25-050-25 (which the 1000 Series manual says is only for the 1042) and the under-hood sticker says to use a #12-050-08 which I've never seen anywhere! Did it come with the wrong filter on it or what have other folks used? Does it really matter? The dealer I bought it from tried to sell me a Cub Cadet brand filter labelled only for the Kohler Courage... Thanks for any advice.
