I had forgotten about the yearly shipment of mower blades and they came at a perfect time. Thanks Sears for remembering over a year and sending new easy to install blades.

42" Deck, 21.something blade
Just to be clear I purchased 2 of this 21" blade for my 42" deck quick release tractor. The only difficult part was getting the plastic cover off. Must squeeze the two releases in to release and pull them apart to put back on. I had to use a screwdriver. Remainder of repair was easy. Once the cover was off there is a metal release then used a screwdriver to pry release bar up. I am a 63 year-old DIY woman! I have a jack to lift up front of tractor to make it easier to get under it.

Easy to install
The diagram shows only one blade and shows a cap assembly over and under the blade. Ordered assembly, only one cap in it. Ordered one blade but mower has two. Had to order two of each. The cap assembly is 34.50 each for the plastic. Blades are only 8.81?? Really?

Easy to install
Installing the blade takes seconds. Most of the time it takes to install the blade is spent jacking up your mower or removing the mowing deck to get access.
