I’ve been really happy with this mower so far

I’ve been really happy with this mower so far. It started up without much effort, and the 144cc engine has plenty of power for my yard. The 17-inch deck is a good size for getting into tighter spaces while still making quick work of mowing. I also like the 3-in-1 feature since I can choose to bag, mulch, or side discharge depending on what the lawn needs.

The mower feels easy to push and maneuver, even around trees and flower beds. Assembly was straightforward, and it has performed reliably every time I’ve used it. If I had one small complaint, it’s that the grass bag fills up fairly quickly on taller grass, but that’s expected with a 17-inch mower.

Overall, it’s a solid value for the price and a great choice for anyone looking for a dependable gas push mower for a small to medium-sized yard.

The design is excellent

The design, weight, & looks are excellent. However, it felt flimsy like most equipment of today. The grass catcher bag frame doesn't seat properly onto the slots holder. Either the frame is not leveled or crooked, or the the slots holder wasn't aligned when welded onto the mower rear body. Therefore, the discharge door doesn't seat precisely. The engine starts right away and I'm hoping it'll last for more than a decade as my previous lawn mower did. Overall, I'm very happy with this purchase! As a first time PowerSmart customer online, I wish the shipping communication was more clear to assure customers are not being scammed. Thank you!

Good Mower

Very easy to assemble. Not super duper heavy but not very light. Very easy to use and the bag holds more than I thought it would. Perfect for collecting the grass for our compost. Overall a good mower for the price.

How the mower just glides across the yard.

Absolutely thrilled with my new gas powered Power Smart Easy Glide lawn mower. Being a single woman with my own home makes for difficult tasks sometimes. Especially when it comes to the yard. I enjoy my garden and hate mowing but the new mower makes the task super doable. Have used it twice and it’s been a breeze to get the mowing done with the almost self propelled feature I fond it quite easy. The blades cut through the tall weeds with ease. Thank you for the engineering that makes gardening my primary task in the yard against . Can you believe from the photo that the grass was 18” tall?

Love it!

I am very happy with my purchase of this lawnmower. It has been working great and it was easy to put together. I’d easily recommend it to anyone else. It cut the grass nicely and these was no jam issues. It doesn’t come with gas so you have to go and buy one that’s the only downfall

The most efficient and economical!!!

I am very satisfied with this lawnmower. It works perfectly, starts without any issues, and cuts the grass evenly. It is very easy to use especially for us, as we are beginners at home maintenance and we haven't encountered any difficulties while using it. The grass catcher is quite practical and helps keep everything clean. Furthermore, it is very affordably priced for the quality it offers. We have used it several times, and it has always performed excellently. I definitely recommend it to anyone looking for a reliable, efficient, and economical option!!!!

POWER SMART 144 cc 21 inch 3-IN-1 Push Lawn Mower

My new mower arrived very quickly, was packaged safely and without damage, and with all instructions/parts present. My son and I were able to remove it and assemble it quickly and easily. It started right up, pushes easily, and works as it claims and should. Overall I am very pleased with my purchase. Thank you.

My Lawnmower

The lawn mower was shipped on time it! Its practically put together for you, you only have to of course put on the handle. It is kinda pricey and a bit hard to push but the mower cuts great! It’s a bit loud which is expected for a gas mower.

This mower makes our yard work so much easier!

The media could not be loaded.









Our old push mower finally quit working in the fall, so we really needed to find a new one this spring before summer hit. We’ve been extremely happy with this 21 inch PowerSmart push mower so far. It was super quick and easy to put together because it took less than 10 minutes total to set up and we were ready to start mowing! It starts up easily usually on the 1st pull and has been running great for the past month with no issues. My husband especially loves using it around all our trees and along the ditch banks in our front yard to cut back on having to use our weedwacker for all of those areas like we used to. It’s lightweight and easy to maneuver, so it handles those tighter spots and uneven areas much better than a big, bulky mower would. It’s not heavy or awkward, which makes a big difference on a hot day when you're already struggling to get all the yard work done.The height adjustment is simple to change, and I like having the option to bag or mulch depending on what we need. Plus if you want to remove the bagger altogether it's a breeze to just quickly unhook it and leave it off completely which we do for the steeper ditch area. It’s also been very low maintenance so far, which is always a huge plus. You can tell by the solid construction of this mower that it's well built and has a durable metal body. You also don't ever have to worry about the tires going flat since those are low maintenence solid hard plastic tires that don't require any air. For the price, this mower is a great value. The 144cc engine has plenty of power to get the job done without being too much. Overall, it’s just a solid, easy to use mower that gets the job done without any hassle and I'm happy we ended up going with this model of mower.

Do NOT purchase this mower

The mower runs hard. The motor runs rough and the foam cushion on the handle already ripped. All of this after the first use.

I would pass on this mower and spend the extra $100 to get something better. Cause now I have to buy a different mower.

Hello,
We’re very sorry to hear about your experience with the mower—this is definitely not the performance we expect, especially after the first use.

The issues you described, including the rough engine operation and the damaged handle foam, are not typical and may indicate a defect. We’d really like the opportunity to make this right for you.

Could you please contact our support team with your order details and, if possible, share a short video or photos of the issues? This will help us quickly assess the situation and provide the best solution, whether that’s replacement parts, repair support, or another resolution.

Easy assembly!!!

Great durable push mower for women who have lazy spouses in their lives who don’t want to put anything together or for anyone who finds it hard to assemble things. Definitely easy to assemble. It didn’t take me very much time at all. It basically came assembled except for a couple items you have to attach. The directions were easy to understand. I was so excited at how easy it was to raise and lower the blade on this mower. One lever to lower and raise. Oil is included, as is a wrench for the spark plug. I got the mower with the bagger, but I have not used it at this point. I will give it a try at a later date.The mower is easy to handle and moves smoothly. I had no issue starting this mower. After I put the gas in, I primed up the mower by pushing the red button, pulled the cord a couple of times and it started. It did take a couple of pulls, but that was expected since it was brand new. It folds up easily for space saving. So far I’m happy with my purchase!
