Craftsman Advanced Mulching and Bagging Blade. For 21 inch, 22 inch, 42 inch, 46 inch, 50 inch Decks.
Craftsman has introduced the best mulching and bagging blade for your mower. I have been using this style of blade for over 20 years on both my commercial and homeowner mowers and hands-down this is the best blade you can get for all of your mowing needs.
21 inch Advanced Mulching Blade
The original inventor of this style blade named them ‘Gator Blades” because they chew and cut your grass clippings, leaves, and debris into tiny pieces. The clippings are cut up much smaller than what is left by the conventional Craftsman mulching blades you now have on your mower. In fact, I think these blades are equal to or better than the Snapper “Ninja” and the Toro “Recycler” blade systems. I currently have this style of blade on my 30″ riding mower and my 21″ trim mower. I have both mowers set up to mulch and I don’t even think about picking up leaves. The blades just make the leaves disappear.
The blades cut up the grass clippings much finer than conventional mulching blades and because of that you have fewer problems with thatch build-up in your lawn. The smaller clippings decompose more quickly and help fertilize your lawn. On bluegrass if you set your mower to 3 1/2 to 4 inches and aerate every two years you will effectively eliminate the need for fertilizer and weed control. (The clippings fertilize and the higher setting shades the ground so dandelions and other weeds can’t grow.) I can show you a 2 acre lawn near Albany, Ill were this type of blade has been used for about 10 years now. The bluegrass lawn is so thick and weed-free that you can sleep in it.
The Craftsman Advanced Mulching and Bagging Blade also throws well so it doubles as a great bagging blade. The advantage for bagging is the blades cut up the clippings a lot more than conventional bagging blades so you can get a lot more into your bagger. You will be pleasantly surprised at how well dry leaves get ground up.

You need to be aware that this blade cuts and mulches differently than a conventional mulching or bagging blade and it will leave a mess if you try to mow tall grass when it is wet. This is only a problem usually with side discharging and during your lawn’s high growth season. For example, you didn’t have time to mow your lawn last week so you need to cut 4 or more inches off. And this week the only time you can mow is early in the morning when there is a heavy dew or it’s been raining all day. When you mow some of the clippings get left on top of the lawn because of the excessive amount you are trying to cut and it being so wet. The next day when they dry it looks like Fluff or cotton balls all over your yard.
There are two things you can do to fix this or keep it from happening. First, if you have to mow when the lawn is long and wet ….. SLOW DOWN! Mow at half the speed you normally mow at. This will give the blades more time to chew up the clippings. If you are side-discharging overlap your path so you are cutting the clippings twice. Second, after the lawn has dried and you have this “fluff” all over your yard don’t feel you have to rake it all up, just go back and mow it again. The fluff will disappear.
