undercoating a mower deck?

I have read several ads for mower decks for sale indicating they have been undercoated? Anybody do this? What are your thoughts?

Re: undercoating a mower deck?

I use epoxy paint or equivalent. If dried concrete can't stick to it, that is good enough for me.

Code:

Re: undercoating a mower deck?

So far I have just cleaned mine real good every fall when I take it off. It's still red underneath? No rust to speak of. The deck has reached the point were it looks really dull and dirty in spots and has a few small surface rust spots (very small), so I was thinking of some paint work when it comes off this fall.

Epoxy paint, that makes good sense to me.

Re: undercoating a mower deck?

I think the decks rot out when they are allowed to sit outside and the moisture builds up underneath. Decks that are used alot seem to last the longest. When I work on a deck, I usually clean it up as best as I can then use apliance epoxy spray cans. The decks that I have in storage I keep up off the ground and spray with wd40.

My tractor, and its accessories, have never spent the night out doors. My garage is not heated (at least not unless I am working out there in cold weather), but it is insulated and dry. And my deck is in good condition, just ready for some cosmetics.

I used spay can appliance epoxy on my recent wheel and wheel weight repaint - I'm very happy with it so far.

WD40 makes for a miserable rust preventative. Almost anything else is better. LPS3 is pretty good.

I would need a warehouse to keep every thing indoors. I was just saying that the decks I've seen that had real rot issues spent a long time outdoors and most where on tractors that had sunk into the ground. On a working tractor I don't think it is an issue. So the answer to you orgingal question is that I don't think undercoating your deck is worth while. I'm also aware of wd40s limitations, but I get an endless supply of it for free, so I make the best use I can of it. The other problem with undercoating the spindles is that you may hold in heat and lead to premature bearing failure. Ed

Re: undercoating a mower deck?

yes plus if you leave the grass buildup under there too long, it will rust underneath those blobs that grow over time. also i would assume the more wet grass you cut, the more you have to keep an eye on things under the deck.

That is probably true, I do blast mine with the leaf blower on top and underneath to remove clippings and dust before I bring it into the barn. They used to make an adapter for your garden hose to attach to your deck but it seems like the worse thing you could do to it before putting it away, Ed

Re: undercoating a mower deck?

If you have been cutting wet grass spraying with a garden hose has to be better than not doing it,other wise blowing it with compressed air is my choice and sealing exposed metal with any paint has to be better than none JMO

Re: undercoating a mower deck?

To me the key is pulling the deck off several times per year and cleaned out underneath. As long as you don't leave grass packed under there that retains moisture - rust shouldn't be an issue.

A lot of the newer push mowers I looked at had that. A simple hose female hose fitting on top of the deck, you were supposed to hook the hose up and run the mower for a minute or two to clean it. Not sure it is intended for each mowing. I think it's a good concept, just not sure how well the execution would be.

The grass under there does a lot more than retain moisture.. It begins a chemical process that produces Nitrogen and other 'deck-unfriendly' chemicals which eat things up faster as well or more than just the moisture. Lots of good ideas shared here for your consideration.. The best thing is mowing when the lawn is dryest as it won't promote the decay or mulching process as much and deck clean-outs when you do help a ton.. I rebuilt a few decks lately and applied rust converter to them in my attempts to retain what metal the decks have left.. Jury's still out on that method though.. Time will tell.. (*I might try the appliance paint if I ever get a newer deck!) Good luck and hope you find something that works!


Experience is something we get.... right after we needed it!!

Re: undercoating a mower deck?

I've used pourable 2 part roof sealer. Turns to rubber when cured. I did my Ford LGT deck about 10 years ago and it's still holding up well. Grass doesn't stick to it very well, and even when it does, the amount is so small that it's not worth scraping off and possibly ruining the rubber coating.
