I bought this as a replacement blade for my new Greenworks lawnmower. Have not used it yet but I am sure it will work as well as the existing blade. I am very pleased with the lawnmower and how it cust the grass!
I purchased new blade because old one seemed to not cut as well. Every one should have a new blade on hand in case. Perfect fit and uses less battery with new blade.
I like to have two blades and rotate them frequently. The blade not being used gets sharpened when I have time. A sharp blade not only cuts better, but uses less battery power.
The online video was easy to follow, and the replacement took only a few minutes. Very simple. New blade cuts well, and I am well satisfied with the product. Make sure that you buy the blade here. This blade came with the arrow shaped notches and fit my mower. perfectly.
After whacking a hidden stump with the mower, I realized that the impact bent the blade. The mower shut off instantly on impact. The blade was seriously bent. The good thing is that the mower was fine. Way better to replace a blade than damage the shaft or motor on the mower. Whew! I'm assuming it is designed to do that. After some brief confusion about which blade to order due to some bogus comments on-line, I ordered the blade. It arrived in good condition. It took a few days longer than I thought it should, but we are spoiled now-a-days with super fast fulfillment times.
Anyway, changing the blade was amazingly easy, and I'm back to mowing, but with a little better awareness of obstacles.
