Toro offers an enhancement kit for my 42” fabricated deck which I considered. I’m confident that it will improve collection of clippings. My concern, and the reason that I didn’t purchase the kit, was it will create areas where clippings will collect and lay on the baffles (like small shelves). I think this will substantially increase the difficulty in cleaning the deck and potentially corrosion. I flush my deck with the water hose cleaning adapter every time I use it. I’ve also occasionally treated the deck with Gunk mower deck spray. So far it’s working pretty well.
