Ratings & Reviews for Kobalt 20-in Deck Multipurpose Mower Blade for Walk-behind mowers

na

wrong one

Does not fit

I ordered this online. When I tried to install, the holes don't line up. They are about a quarter inch off. I went to the store and returned it. Went to the rack where there were two Kolbalt choices. Neither one would fit.

Just replaced my blade

Before I went to my Loews store, I read the many negative reviews of what Kobalt is offering as a replacement for the original blade on the 20 inch deck mower. I brought my old damaged blade with me and matched it against the blade in the store. Purchased the new blade, put it on the mower, and started the mower up. It's working fine. Maybe there are other Kobalt blades out there that don't work, but the one I got does.

Wrong part

It was the wrong part..

Just what I was looking for

It was easy to find in the store and there were multiple on hand so I didn’t have to worry about anything. Easy to install and works well.

Fits Gen4 40V Self-Propelling mower

Decided to replace the blade for my Kobalt Gen4 40V Self-Propelling mower. Lowe's search yielded this one. Checked all parameters and description - should fit, but negative reviews caught my attention and that's the reason I'm writing this review. I bought two blades, one has older version of packaging, another one has new version. Both old and new versions of packaging clearly states item number (4357211) and model (40V Max) - check that whatever you have picked up in Lowes has your model on i...

Trust Lowes

it was exactly as I ordered

Doesn't fit.

Bought this blade in lowes for my 40V Max 20 in mower because it says that on the description. Flipped my mower over to remove the old blade and noticed the fitting is not the same. Not only that, but kobalt no longer sells the original blades. I will have to try my luck with a greenworks blade. Unfortunately I lost my reciept so i cant even return the thing.

Kobalt Mower Blade

Didn't fit my 4yr old mower and can't find a replacement that fits.

Boycott Lowes. This company stinks.

Came to Lowes for help finding blade for Kobalt mower bought only 2 yrs ago, a man from mower dept ordered a blade for me and it came to my house with an added 5.99 shipping, so when I went to return blade that did not fit, shipping cost was not returned to me. Also a blade does no longer exist for this mower. I was literally left now with a useless mower. Lowe's did not try to rectify this issue at all. Time for me to move on from this useless company after spending thousands of dollars thru th...

Good Blades

The blades fit like they should however they are very thin and bend very easy. All together they are good for the mower and sharp.

Looks good, have not used it yet. Quick shipment.

Does Not Fit-KM-20418-06 40V max Mower

This blade does not fit, wrong shape and spacing of holes, also wider than the guides on the bottom of the motor. Lowes sight redirects to this blade when searching for the 0812963 Blade listed in the manual. Typical Lowe's, no support, just go buy a new mower. I will do that, but it won't be from Lowes. Only gets 1 star because the don't have Zero.

Not compatible

Not compatible with my Kobalt lawn mower as stated in the description.

Does Not Fit on 40v Max, KM-204 1B-06

The previous reviews about the replacement blade not fitting are now painfully obvious, see photos. It DOES NOT!!! Because of those reviews, I called Kobalt on the afternoon of 8 July 2024 and spoke with a CS member. I was assured it would. The gentleman even took time to research it. He seemed professional, so I gave him a good review for his customer service. It is not his fault that Kobalt has the WRONG information in their database. I hope they can fix this problem as the mower has been do...
