    • Overgrown Grass? No Problem! 🌱✅
Size: 21 Inch

Honestly, this mower did way better than I expected. My grass was pretty overgrown and I thought it might struggle, but it handled it like nothing. It cut through thick grass super easily and didn’t get bogged down at all. The lawn came out looking really clean and even, and it’s really easy to use. It’s also super easy to maneuver, especially with the self-propelled feature, it makes pushing it around way less work and a lot faster. Overall, I’m really happy with it. It did an amazing job and made the whole process quick and simple. Definitely recommend if your yard gets a little out of control like mine 😅 ... show more

    • Absolutely yes
Size: 20 Inch
I am in love with this mower!! I have tried all kinds of push mowers over the years and the last few have been extremely temperamental when it comes to the pull start. NOT THIS ONE--it starts right away every time!! This has been wonderful. It's lightweight and does a great job with multiple height settings available. I didn't want any bells and whistles--just a basic mower that I could work with easily--this is the one!!!! ... show more

    • Seems really well built
Size: 20 Inch
Arrived on time and as described. I looked at a model with a Briggs and Stratton engine, but apparently the one I ordered doesn't have a Briggs? Probably why it's a little cheaper on Amazon. Anyway, it still seems really well built and cut through slightly wet & overgrown grass with ease and it started on the fourth pull. I'm happy with it so far...... Update....... I've had it for a couple months now and it's definitely a good mower. ... show more

    • Would not recommend this model
Size: 20inch-144cc-3 position
I should have paid more attention. This mower has three-wheel levels that have to be changed by removing the wheels and reinstalling them. It also has no mulching cover, and the side discharge chute throws out directly not down. Not happy with it but will not return.

    • Great mower
Size: 20 Inch
Used this a few times already, starts right up and works perfect, great price and value

    • Great little basic mower
Size: 20 Inch
Works better than expected. Easy to start, and plenty of power. Cut through a fairly overgrown lawn wet with dew with relative ease. Never skipped a beat. Can't speak on durability yet since I've only used it once thus far, which is why I haven't given it 5 stars

    • Cuts nice and low
Size: 20 Inch
My husband is happy with the quality of this lawn mower. It cuts close on edges and was easy to trim the grass on the side of our house. He was able to cut the grass low enough that we may only need to mow one more time before winter.

    • Easy pull start
Size: 20inch-144cc-3 position
Was fairly easy to assemble. Came with oil. Primed 3 times then pulled cord to start. Has 3 height adjustment.
