I just got my 75742 and looking to get some gator blades on them to pair w/ the recycling kit once i pick that up and trying to find which model will work with this mower. technically i think the stock blades are 21.6" so i'm pretty sure I'd just be fine w/ the 21" G3's but thought i'd see what everyone thought.

so far the stock blades and side discharge works very well but was recommended to go this route for a more superior leaf mulching

cool thanks for the help here! i just now saw too that my mower also goes under the model SS4225. and their product finder lists the G6 21-9/16". Mulching Blade, Gator® G6™, 21-9/16" | Oregon Products

little more expensive but probably better to go w/ that since it matches the size better? (little heftier too)
