Rated 5 out of 5 by from Works as expected I had the original blade for almost 2 years. I hit a few rocks and sidewalks so it was definitely time to change it. The new one gets the job done as expected.

Rated 5 out of 5 by from Replacement Blade Saves the Day Works great! First time I installed it there was a bit of a vibration when going at an angle in my yard. I took it off, cleaned off the all the contact points for the blade and it’s accessories, and it works like a charm. Admittedly, I had waited 6 years without replacing or sharpening my blade. And in that time I had managed to hit the blade on bricks several times. So my bar was pretty low, but the new blade made mowing even my overgrown lawn a simple task. So much easier to cut through, and the lawn was much greener now that the grass is being cut rather that whacked.

Rated 4 out of 5 by from Blade needs clearer instructions Blade arrived quickly. Easy to replace. I just wish it was marked better so that I knew which side faces the ground and which faces up.

Is this a Mulching Blade? Not found on sales pages. Also, same metal grade as gas blades?

Asked by: Seattle Paul
Hello Seattle Paul, While not a designated mulching blade, it is designed to be ample for the three discharge forms that our units offer (grass catcher, side discharge, mulching). This blade is made of steel.
