21" Lawn Mower Blade

Mower arrived quickly, easy to assembly. Works great.

Delievry went well and on time

This item was deliver later than my two other orders. It is exactly as discribed, high quality.

Now my mower cut like new One

These are great mowers and blades. The Greenworks 80volt lawn tools and battery system works very well. Plenty of power and batteries hold up very well. I have had the mower edger string trimmer and blowers for over 5 years now. They all have held up well and continue to work great. I use all these lawn tools to maintain 5 to 6 lawns per week during the season and so far a great experience. Quite reliable and very convenient to use.

Just took a while to figure out that Greenworks made my Lowe's Kobalt 21 mower. Can't get the blades from Lowes!!!

It fit my kobalt mower perfectly

Fit perfectly. The old one was tough to get off but the new one went on easily

Having a second blade is very convenient. Its nice to have one in the mower and then I can sharpen or have a shop sharpen the other one as time allows

I grow my grass to 3-4 inches. Other blades weren’t able to cut all the grass I mowed over. This blade does a superb job of lifting the grass to be cut thus cutting all the grass evenly.

I have had my mower for a couple of years and it's great. Now with the purchase of the new cutting blade it cuts like brand new again!

Okay it's a piece of metal. It spins and cuts the grass. Either it works or it doesn't. This one does so therefore the positive review.

I ordered my replacement blade a few weeks ago and I have been very pleased with how it cuts. Easy to change too. Thanks

I had put my old blade through the ringer and I had put off replacing it because it was such a tricky prospect with other brands. This one was easy and quick and now my mower is cutting like a dream

Easy to change and fits the Kobalt 21 80V mower which is great because Lowe's is constantly out of stock!

None is stock at Walmart Home depot or Lowes. Had to order from the company. Was back ordered from them. Took over 2 weeks to get it. New Blade worked well.

When will this be available? My 2 month old mower is already showing signs of wear on the blade. I need to new one urgently.

Any plans to restock this? It’s the blade I need but don’t seem to be able to buy/order one anywhere!

Clearly the company has a poor manufacturing supply. The 2 different 21inch blade choice makes no sense and the seasons are quite predictable; how do you tell people that you might get blades by End of June Maybe??? Would not buy the cordless 80v mower again!

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.

The mower blade was easy to install to get the job done.

Purchased this product as a spare received the product quickly and was pleased with the overall process.

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.

I have a Greenworks battery powered mower which I bought at Lowe’s. They don’t carry the mower blade I needed and I needed a specific blade that fits this mower. I found it here and am happy I was able to replace a blade which was damaged by a rock I couldn’t see before running into it. I received the replacement blade quickly.

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.

Unbolt full blade. Remove. Replace with new blade. Replace bolt. Resume use of mower.

FYI - there are TWO 21 Greenworks blades. I went to Amazon and indavertendly ordered the incorrect blade thinking there was only one. It arrived couldn't be installed. I checked the Greenworks website and discovered there were 2.

Excellent blade easy to install ordering process needs to be better.

Happy with my replacement blade. It was vey easy to install.
