  • Ease of use and getting ready
Size: 21-Inch
Received my new mower yesterday B8721S2 - took it out for a spin this morning - short assembly, notice this model is a No Prime, No Fuel Cutoff Valve, No Stop Switch other than the handle, and no other throttle control other than holding down the stop/start bar as usual. Once got the handle up and in place, filled with oil and filled with gas - held down the start/stop bar, pulled the recoil starter handle and we were off to the races, on about a 3/4 pull. The speed of the self propell part is a little fast on solid surfaces, but in the grass provides more than enough pull to get it thru the thickets of grasses - all in all works pretty good. ... show more

  • DON'T BUY NOTHING BUT FRUSTRATION
Size: 21-Inch
Please refrain from buying this machine, the reason being I bought this machine so I could use it on Father's Day weekend, and as soon as I took it out of the box, I noticed a problem. The machine has a wheel lifting setup where all wheels are controlled by a single lever. However, I found out that this lever is poorly made. There's no other way to lower and raise the machine so im stuck with it on the lowest setting, so I can't use it. I went on the PowerSmart website to get a replacement piece which I was able to order for an additional $12 after the $10 part price. I am now still waiting on the piece, its now/11 and I just got a FedEx notice that a label for shipping has been created, but nothing delivered yet. This is ridiculous, and of course, the lawnmower isn't returnable, so unless you want to be frustrated with this item and the cheap parts, steer clear, bad purchase. ... show more

  • Great cutting machine

This lawnmower did very well in cutting my jungle down to size. Was very Leary of its ability to cut. Very pleased of this mower.

  • Quality is lacking
Size: 21-Inch
Do not buy - came with a cockeyed right wheel out of the box but I thought if it works who cares. It was easy to assemble and it started right up after adding oil and gas. This mower is fast so the user needs to be strong. Less than 15 minutes in mowing the rubber matting that lies beneath the discharge bagger was eaten by the blade and spit back at me for no reason. Nothing was hit. It was flat grass. I did notice when I pulled the rubber mat out of the box it was bent from shipping so I guess that's what caused it to get stuck under the rotor. So if you still purchase recommend you put a heavy book on this rubber piece to flatten for a day or two. I hope to reach the sellers to get a new one sent to me - and a wheel. I called them but they were closed for the day and Amazon gave me the Oops somethings wrong on their end error message. ... show more

  • No Side Discharge
Size: 21-Inch
No side discharge. Was not aware of that when I bought it. You could not tell from the picture. It's a nice machine so far.

  • Started on one pull right out of the box!
Size: 21-Inch
I just needed a rather inexpensive mower to get to areas my riding mower can't, and this fits the bill after extensive research. Very easy to set up - about 5 minutes. Manuel's are worthless. Fill with gas & provided oil and go. Started on one pull - unbelievable! I have had Toro's and Honda's and one pull would be rare. Loud, quick and plenty of power. Plan on taking care of it with oil changes and draining gas in winter. If it breaks down, I will update. ... show more

  • Poorly made
Size: 21-Inch
Right out of the box added gas and oil. Started on 1st pull. Tuned off and oil leaked out under mower deck where blade goes into engine Leaks oil when not running. Non-transporting back to China but Amazon made it right. Cheaply made. Wheel tread is plastic and probably have slick wheels after one season. ... show more

  • Easy t
Size: 21-Inch
The lawnmower was easy to assemble. It is easy to start and well built. We like that it is self propelled! No problem mowing the lawn now. We give it 5 Stars! The only problem was the Amazon driver delivered it to the wrong address. The owner where it was delivered, could have kept it, but was honest and brought it to us. ... show more
