  • Easy to operate
It takes the sweat out of mowing.

Just what I was looking for

  • Don’t buy this!
I bought this machine and used it once. The next day it wouldn’t start. When tried researching what could be wrong with it I discovered this is a common problem with this brand - it stops working after a few uses. Save your money.

  • Falling apart already - STAY AWAY
**UPDATE** The grass catching bag is already ripping away from the seam and the self propell went out during second use of the lawnmower. This lawnmower was easy to assemble, and started up on first pull. It cuts very good. If there is a drawback to it, the self propell is pretty fast paced! But all in all a good mower. ... show more

  • Sorry I purchased it. Shockingly bad.
No way to adjust walking speed, you’ll have to run to keep up with it. Carburetor floods every few minutes requiring a ten minute wait. . A piece fell off the bottom on the first use. It guzzles gas. This mower is terrible and it’s hard to believe it was manufactured by a major company. Shockingly bad. ... show more

  • Lawn mower speed
On my initial usage the speed was set faster than walking speed and there is no way to modify the speed. On the the second usage the self propelled function would not work.

  • Cheap
I hate this mower and Amazon won’t let me return it. Mad at good reviews for it.
