In principle this should be true, but in practice it isn't. The aluminum deck won't rust but it WILL corrode, it turns to white dust.
The aluminum alloy that Toro used prior to about 1990 (and still being used in the commercial mower decks) is different than the aluminum alloy that they are now using in the consumer mower decks. In the old days with the old aluminum alloy, Toro mowers would last forever if you didn't run over something and break the deck. The 1994 model Super Recycler that I currently have has been an excellent mower! It still mows superbly, the Briggs L-head engine has been excellent, and the power drive system has performed flawlessly. The problem with this mower is that the deck has very nearly corroded away completely. I patched it up with fiber reinforced Bondo and am still using it, but the mower is definitely on it's last legs. I contacted Toro to ask them if they had corrected the alloy formulation on the newer models and the answer from them was that the alloy currently being used is the same as it was in 1994.
For this reason I personally would not (and will not) spend the extra money to upgrade from the steel deck to the aluminum deck, but, I will still buy another Toro and wouldn't hesitate to get it with an L-head Briggs engine.
