Easy Install
Easy to install, The blade is working as expected. The blade cutting edge is painted. I started using it with the expectation that the paint will wear off without sharpening. It seems to be cutting the grass without scalping with no sharpening or removal of paint from the cutting edge. I have not inspected the cutting edge after mowing several times.

Fast, easy replacement solution
Hit a tree root and bent my old blade beyond repair. Ordered this online and it was delivered fast. Not the sharpest, but easy to install and gets the job done. They include several different size/shaped washers to adapt it to your mower.

Excellent replacement for 21” troy bilt mower
Excellent universal blade. Works wonderful on our 21” troy bilt push mower. Cuts the yard nice and clean.

I haven't installed it yet because the old blade seems glued in place. Sprayed some WD40, hoping that works.

I have an older lawnmower and I was having issues finding the needed replacement blade. This was perfect!

The blade is pretty basic. I had to sharpen it first thing because it was just whacking down the grass instead of cutting it. Now it works great! Budget friendly though.
