Easy Install

Reginald July 23, 2025

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

TIFISHER August 3, 2025

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.

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

Arieh July 17, 2026

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.
