Thanks Paul,

I had a look at 3 Evolution series mowers yesterday, including one brand new one and 2 of them were bolted to the inside (including the new one) and one bolted to the outside.

I also found some old pics I had previously taken of my mower, and it was definitely bolted to the inside, so I am perplexed as to why some are and some are not and if it makes any difference.
