how do you treat old rusty decks ?

bought a used exmark wb and john deere lawn tractor , both from year 2000 , over winter at real good prices but they arent in top shape with both of them having their decks left full of caked on grass without being cleaned a long time which led to deep rust penetration so im wondering folks methods to stop the rust and protect the decks ? decks arent near rusting through but easily over a 1/16th has rusted off

Wire brush the rusty spots and use a rust converter. Then some touch up paint.

im thinking you thought im talking about top of deck by you saying touch up paint , but im talking about bottom of deck which are nearly totally rust coated

by habit ide steel brush then either brush on used truck oil or brush on oil based rustoleum primer , but my methods are just self thought so im wondering if maybe there could be better ways to insure stoppage of rust

i used a rust converter spray on product on my truck before and it didnt help too much so im just putting out feelers to hear others experiences

If you really want to stop the rust, you need a rust converter like this http://www.ospho.com/

Then you can prime & paint.

thanx . ya ive been thinking prime n paint because these are both well designed old mowers that still have many years in them if theyre maintained . even if they end up needing new engines im all for not wasting , and these can both be used for home owner stuff plus back ups on our route for a long time . so i want to stop the rust

Brush some used motor oil or spray some rust penetrant on the bottom and mow, but not near windows, theres no way to get anykind of paint to stay on the bottom of the deck.

ive always wondered about painting bottom of deck but never have so theres the answer . figured there was some reason manufactures didnt do it . so guess i'll put a brush on angle grinder and brush heck outta them then brush on the used motor oil like usual

wonder if i add in some kerosene or gas to oil if it'll penetrate better into deck ?

Yea I thought you meant the topside. Nothing keeps paint on the underside. With our sandy soils the powder coat is gone in a 100 hours. I do lots of patching in a decks life. The grit wears right through them.

never dawned on me sand would grind away at and right through deck

makes me wonder what would happen if i threw a bucket of sand on concrete then ran mower with blades running over it and shute closed off if the sand would blast away the heavy build up of wet grass clippings we get here in michigan during spring ?
here in rich loamy to clay soil with no sand and heavy wet grass conditions many times weve got to stop during the day and prop up mower to scrape packed on tight clippings off deck or it'll start bogging down . i guess the sand would dull the blades though ? even if so if the sand blast technique would work ide use it when blades need to be sharpend as that way would save me 15 minutes of scraping deck or pulling out pressure washer and making a mess with wet clippings

Remove the spindles, sand blast, prime with a good etching primer and then paint. Or better yet you could take the deck off and sand blast it and have it powder coated. No matter what you do it will eventually wear the paint or powder coating off the bottom of the deck.
