Disc Mower Conditioner Clean-Up?????

End of the year, cleaning hay out of the baler, easy peezy.

Looking at some used disc mower conditioners, roller and impeller versions and WOW - what a mess under the hood!

How do you clean-up your moco after using it? Never liked using a pressure washer out of fear of mashing water into otherwise unpenetrable places, like a bearing seal. Hose it off, do nothing? I'm thinking the do nothing route might lead to some rust out issues down the road.

How do you deal with the crud build-up under the hood of your mower conditioner?
