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.

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.

Rated 5 out of 5 by from Just like the original! It was a very good price, too! The blade costs about the same as two sharpenings.

Rated 5 out of 5 by from Very good product. I had been using my mower for last 4 years, and just like an average user, I never sharpened the blade and did anything to take care of it. This year I thought I'd take a look at it to see if I can sharpen it myself or take it in to get it sharpened, but when I saw this I just eneded up replacing the blade all together. It took a total of 2 minutes to do the job. Just unscrew the bolt, take the old one out and put the new one in and screw it back in. Its that simple. If you have a bolt that's rusted it might be a different story though :). Anywho, make sure you unplug the spark plug before you work on it. Also, I did this while I was chaning engine oil, so I took the old oil out, took the blade out and put the new one in, stand it up and put new oil in and then gas and BAM! started right up. Much quicker and simpler than trying to find a place to sharpen the blade or if you do it yourself, then having to worry about about balancing the blade etc. ....well worth the money.
