It looks very nice indeed, Chris. Please don't mow with it without a full set of engine mounting bolts, there is way too much risk of cracking the deck under the engine. Note in regard to your SB45, the ones like yours with the two-rail deck are prone to cracking the front rail at the inboard engine mounting bolt, so keep an eye on it and treat it reasonably gently. Sometimes it seems that most of the running changes made in the SB45 during its long production life were for the worse.
