Just what was needed
Well the lawnmower is already 5 years old, so the blade was less than good. Sharpening didn't help much as the OE blade had many nicks and warps. Then I found you guys, and voila, problem solved! Installed in a breeze, works like a charm. Thanks

OEM-part better than what else is on the market
Perfect fit compared to the "universal replacement" non-OEM "stuff" on the general hardware market. Wasted my time looking all over. Should have gone directly to e-replacement. They never let me down.

Use a glove or rag to hold sharp blade, loosen mounting bolt and then remove bolt, the blade insulator, and the spacer (square washers) to remove old blade. Reassemble in reverse order with new blade (Note: Ensure the side of the blade that is supposed to be facing the grass is facing out on the shaft).

After tipping the mower onto its side which was easy as it is an electric mower so no gas issues.
I removed the old blade using my socket set and a block of wood to keep the blade from spinning
balanced the new blade
making certain to have the "grass side" facing outward I installed \
I lined up spacers and with my socket set tightened it in place
Ran mower to be certain is was tight and proceeded to mow lawns
