Customer Questions & Answers

Hi! Are mower blades compatible usually? I have a Craftsman push lawn mower with a 20" blade and I'd like to put a mulching blade on it.

Asked by: Anonymous
Not usually Rob. The decks are designed differently to allow for mulching. And most mulching blades are bulkier are likely to contact the lower non mulching decks.

20 in. Replacement Blade For Mowers is rated 4.6 out of 5 by 16.
Rated 4 out of 5 by from There is not much to say. It's a replacement... There is not much to say. It's a replacement lawn mower blade for an inexpensive and simple (yet very practical) push (non-self-propelled) lawn mower. I did learn though that there are plenty of 20-inch blades out there for sale and nothing is interchangeable. All 20-inch blades are not alike.

Rated 3 out of 5 by from No military disc. online The product was fine. The purchase was okay. When I picked up the product, I asked to get the military discount and they wouldn't honor it.

Rated 5 out of 5 by from A Sharp Bargain I flipped the mower on it's side, wedged a 2 X 4 between the old blade and the undercarriage and disconnected the spark plug. I used a large adjustable wrench and spun the old blade bolt out (it was really tight). I paid attention to the way the blade and spacers were facing and everything was back together in about 1 minute. The new blade looks great and cuts the grass without damaging it.
