Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I am considering a Lawn Boy 10797 (Insight Platinum series, cast aluminum deck, 5 yr warranty) and the 10697 (Insight Gold series, steel deck, 3 yr warranty).  Feature for feature, the mowers are the same and both use the Honda GCV160 engine

Does anyone know if, other than the deck material and the length of the warranty, there are any physical or mechanical differences between the two series of mowers.  Lawn Boys web site talks about the "low maintenance transmission" on the Platinum series but does not mention the transmission on the Gold series.  Is this just marketing, or is there actually some difference.

Replies appreaciated.

Thanks.
