Ximoon 2105200317A Lawn Mower Blade 21" Compatible for Murray Push Mower MNA152901 MNA152901 MNA152701 MNA152702, Replace 2105200317 84005221 Mulching Blades Replacement for Tough Mower - 2 Pack

This was very easy to install and it's great quality.

I bent the blade on my mower and am so happy to have found a good replacement blade and as a two-pack it is all the more valuable!!

With this new blade it cuts the grass like never before.

I needed to replace my blade on my 10 year old Poulan push mower...it is 21 inch blade. Two of these blades were in the package. Hint: Keep the extra in the sleeve, pour in a bit of oil and put it away for future. This blade bolted right on...it is made with a universal hole in the center, and there are 2 angled slots that fit the drive pins exactly, at least on my mower. I bolted it up withn 30 seconds. I used a bit of Never-sieze on the bolt to make future changes easier. The old blade was 10 years old. The new one looks great, I don't think I will wait another 10 years to change out this one . This is a well made blade that fits easily.
