i've been removing the fan shroud and cleaning mine out after every season but there's hardly anything in there. i always take the blower and blow down through the fan after every yard i cut. i think it keeps it cleaned out. also i don't cut in the rain. water and dust turn into mud that sticks in the fins lol. i'm gonna wait 2 seasons this next time to check it. they say check it every 100hrs but i wouldn't do it but every 250hrs to be honest. i guess if you cut in the rain alot you may wanna check it every 100hrs because it might be gunked up in there lol.
