Let battle commence!

If that's off a John Deere it will have been thicker than 1mm originally, at least 2mm or more.
If it is a proper USA JD the deck steel on them is quite thick, maybe 3mm.

A 200l steel oil drum makes a good doner for patches because it already has a curve.

I cut the first patch out of the top of the deck under the blade where its not worn much, used a vernier and its 1mm. I think the deck is much thicker in 'places' but those bits haven't rusted through!
It's actually made of lots of bits welded together I think?

Done two more, this one's crowned both ways and was a bar_steward!
I'm using 1.5mm on a 1mm deck, I dread to think how much fun this is on cars?
My Landy needs the bulkhead fixing so this is practice.

Land Rover bulkheads are easy. Had a lot of practice at that.

I have two Honda Izy push movers. The steel decks break in half due to rust after 8 - 10 years. Engines and the rest of it are always fine. I just buy a new deck. Too many other things to do.
