Further to recent post on mowers, it seems that I am doomed - the John Deere mower has a steel deck which of course can rot.

I hear aluminium, plastic etc being mentioned.

Point is, has any reputable manufacturer come up with a mower deck that will not rot, and can mulch properly?

For completelness, the John Deere JS63 when I looked at it was a steel deck - and given that my present honda aluminum deck rotted after less than 15 years I am bewildered and confused about what to do.

any help appreciated
