This is an authentic replacement part manufactured for use with Craftsman walk-behind lawnmowers. The blade is angled to allow the clippings to rotate through the cutting deck to produce fine clippings for side discharge and mulching. Lawnmower blades wear out over time and can cause the grass blades to tear making frayed endings that can diminish the look of the lawn. A new mower blade will allow for a cleaner cut keeping the lawn looking good. This blade is sold as an individual replacement part.

Cuts like new
There were some nicks all along the edge of the old one, this helped even more than expected to cut more effectively.

I am replacing the blade on my mower how do I know I install correct its easy to install upside down
Jim
for model number 23agamp793
asked on 2022-08-21
Hello Jim, thank you for your question. If on the right side, move the blade in a counterclockwise direction, and if on the left side, move it in a clockwise direction.) When doing this, this sharp edge of the blade should be the edge that leads. If it does, then you have the correct lawn mower blade position. If not, you need to flip it over. If you need help placing an order, customer service is open 7 days a week. Please feel free to give us a call. We look forward to hearing from you.

Drilled out broken screw, and used an easy out to remove it. Removed the blade adapter by tapping on it. I then install the new one by lining up the key inside of it with the key slot on the engine shaft. And I tapped it on. I then attached the blade to the adapter with blade support. And the blade bolt and tightened it into the shaft. Works great now.

I removed the blade bolt then the blade support, then the blade. I sprayed some WD-40 on the shaft and let it soak for a while. I was then able to pull the adapter off with my hands. I cleaned the shaft, then lined up the key in the adapter with the slot on the shaft and tapped it on. I installed the new blade and put the blade support on and put the blade bolt in and tightened it.
