  • Lot of mower for the money
Color: Black
Started right up and ran perfectly great mower

  • PowerSmart 21” Push Lawn Mower
Color: Black
The Good: this was relatively put to get and took 5 minutes to set up. I use it set up for mulching so I didn’t need the chute. A quick prime and it cranked on the second pull and the first pull after that. The mow quality was what I expected and didn’t hesitate in my thicker grass. The bad: the rubber flap on the back of the machine lasted about 5 minutes before being caught in the blade and ripped to pieces. It was too long and only designed for the mower moving forward. It was no big deal as I mowed for an hour and a half without anything being kicked out the back of the mower. Conclusion: I am satisfied with this mower and hope it lasts for several seasons. I still hate mowing grass. ... show more

  • Nice mower for the price
Color: Black
Nice mower. Size is nice. I have a decently sized yard in town, so I need something smaller than a riding mower but with enough power to get the whole yard done in one session. I’ve been using a fully battery powered one the last two years, and I’m so glad to have made the switch back to this gas mower. Performed perfectly right out of the box after filling the oil and gas. Knocked off one star because the manual states the mower needs a little over 15oz of oil for first use and at changed, but the bottle supplied with the mower is only 13.5oz. Make sure you have a funnel also, as none came with the mower. Overall, great value, runs smoothly, very easy to set up and get mowing. ... show more

  • As advertised.😊
Color: Black
Received lawnmower today. Very very easy to assemble. All necessary parts and included oil was packaged nicely. Wheel height adjustment is easy to use. Started up on first pull with no difficulty, at all. Able to cut grass quickly and did a good job. Too early to tell how mower will hold up overtime, but is exactly as advertised right now. Does seem quieter than my old mower. ... show more

  • Great after 2 months
Color: Black
I love this push mower. It’s a beast. Has taken on some roots and sticks like a champ. I like push mowers because of the exercise element but this one feels almost like it’s on air. Very easy to handle. You can not attach a bag to it fyi…and the flap came off day 2 but they always do. I have a big yard and lots of ins and outs. Thrilled that it starts on 1st or 2nd pull. Cuz I’m a giiirrrlll. lol. ... show more
