    • Three words...DO NOT BUY!!!
This mower is a piece of crap!!! The transmission unit gave out within three months of using it twice a month. And again within seven months of normal usage. Power Smart is the worst warranty company in the world!!! DO NOT BUY!!!

    • Lawn Mower with no customer service backing.
Bought this mower thinking it would help keep up my lawn. On the first mowing the power cable broke after mowing half the lawm. Called to register warrenty and 5 times that department told me no one was there to help. Then tried customer service and after waiting 1 1/2 hours on lhold got a person. She took my information and said need proof of purchase. I mailed this to her. She took my e-mail address and was to let me know where to take mower after warrenty was complet. Of course no return e-mail I am about to the point of taking to repair shop and paying for repair. ... show more

    • Broken along with my heart.
Piece of crap. It came broken in the box. The lever to adjust the height of the wheels was broken and just tossed in the box. It talks about mulching, but there is no side discharge so clogs easily.

    • 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
