`i` did replace the top deck panels some time back as it was 2nd hand and i`d say they rust out mainly as with the side supports from lazy tractor drivers that don`t clean all the dirt out after use.
One thing i try to refrain from is falling into the habit of standing on the deck or using it as a bridge platform to get to the other side.
My guess some operators have lost their feet over the years due to rusty decks and rotor blades.
 
I'm working on a Cu Mai style blade for a Veggie Chopper, it's coming along nicely

High carbon steel for the core, then 1mm copper (split from 3/4" pipe) and then 2.6mm cladding for the outside of the blade,

It all started off at 200mm x 50mm x 11mm fully Mig welded around the edges, to seal the copper in,

I took it to just past non Magnetic for the first 3 or 4 light hammerings then a tiny bit hotter to draw it about a bit, got it out to 260mm in length and thinned to about 6.5mm

Now just grinding and grinding and grinding,

All sanded to 600 grit and a quick etch in Ferric Chloride and a light sand with 600 grit and then into a very strong Coffee for a final treatment like etching

This is before going into the Coffee solution, the Ferric Chloride tends to make the copper bleed into/onto the steel

the main thing with slasher tops ,don't hose them off use a garden blower ,when hosing them you leave water in a lot of places that should never have water on them hince they start to rust

yes it was a difficult decision to put 1/2 a jar of Coffee into a bottle just to soak the blade in over night, but hey it will be wide awake in the morning 🤣
