I have some small spots on the deck that are starting to rust. The location is the topside of the deck near a few welds and behind the center anti-scalp rollers. I'm not talking about rust from hitting the deck's sides against things (thats normal wear) but rather the finish bubbling and chipping off exposing rust. I store the mower inside and always in my enclosed trailer. I flush the damp grass clippings out from underneath the mower at the end of each weak and wipe the mower down as well. Is this to be a concern? I have seen a few that have rusted out in under five years and have gaping holes in the top of the deck, due to total neglect. I want my stuff to last. For now I will just prime spots and use touch up paint.
