Re: cleaning hood filter
Are you referring to the circular foam "isolator" shown on the parts illustration? I think it is more of an air seal rather than a filter. It allows the engine flywheel fan to pull in air from the vents on the sides of the hood. It is glued to the hood. I would recommend gently brushing off the big chunks with a soft brush and then you could wet it and squeeze it like a foam sponge to remove most of the dirt. Keep soaking with water and squeezing out until it is clean. That's the same way you have to clean the foam filters in some of the new vacuum cleaners.
It would probably be easier to clean if you removed the hood first.
A new foam ring from Deere is $44 but I see you can get 3rd party replacements from Ebay and Amazon for around $28. They have a peel-off sticker and just stick to the hood.
