Ok I found the air filters, thanks. The 'secondary' was completely black. They are both on my list for Monday to go and get. There are three fluid filters I need correct - fuel, oil, and trans. The filter on the bottom (mount on the front of the rear axle is the tranny, right? I can tell it was a John Deere filter, but it is dented in bad, and very rusty. No telling how long it has been since they replace it. Please take a look at Post - 'OK, got my first problem (455)' Thanks
