Second 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.

Replacement blade for Kobalt 21" mower.
on June 7, 2022
Posted by: SLZMS
Verified Purchase:Yes
I have not installed it yet, but it looks like the right blade for my Kobalt 21" 80V mower. The stores have not had it stock so I bought this one online when I found out that the Greenworks blade is the same as the Kobalt blade.

Fits my Kobalt
on May 21, 2021
Posted by: EEng
This blade is identical to the original one on my Kobalt 80V self-propelled mower (KMP 6080-06). I had trouble finding a replacement so ordered this one, and it fits and functions perfectly.
I would recommend this to a friend!

Fits perfectly.

Fits perfect. Hate the plastic bolt though. This issue with the plastic bolt is that the edges round so had to use vice grips to take it off and put it back on. Would like a metal bolt replacement but cant find one.
I would recommend this to a friend!

Backup plan.

from Lawrence, KS
Gender:Male
Verified Purchase:Yes
[This review was collected as part of a promotion.] I bought a second blade from the company so I could have a backup if needed when having the blade sharpened, and rotating blades if needed. It has worked as I planned!
Pros: Convenient, Cost-Saver, Easy to Use, Durable, Effective, Powerful
I would recommend this to a friend!

The original blade is still sharp, but now using this back-up gives a feeling of security.
