  • Good basic mower.
Style: 21in Gas 125CC
I moved to a house with a small yard and wanted a lightweight gas powered mower with NO frills. No bag, no self propell. This fit the bill and price was acceptable. And it started on the first pull! All is good!

  • The BEST lawnmower ever
Style: 22in 150CC Self-Propelled
I needed a good quality mower and this one did not disappoint. It was easy to complete the minimal assembly when I unboxed it. It cuts my yard like a professional did the work. It's not noisy at all and built solid. The self propel option is amazing; it's literally doing the work for you. Highly recommend!! ... show more

  • DON’T BUY THIS IT’S NONREFUNDABLE AND BREAKS
Style: 22in 150CC Self-Propelled
Trying to save you from wasting money on a crappy NOT RETURNABLE mower. We have had the mower for 12 days and it’s already shutting off in while mowing. Tried calling customer service. No one will call us back. The item is non-returnable so we don’t get our $400 back for buying it.. Also, the setting for the accelerator speed is so slow. It’s excruciating to mow the lawn with it. Don’t buy this mower. It breaks and they don’t guarantee it whatsoever. You’ll be flushing money down the drain.. hope this saves someone else from being screwed over. ... show more

  • Impressive mower! Lightweight and powerful!
Style: 21in Gas 125CC
The media could not be loaded. I grew tired of waiting for my husband to mow our lawn. We have an old-fashioned mower and it is quite heavy to maneuver. I quietly ordered this one while on a hunt for a backup for myself and let me tell you it was the best decision I ever made ! Turns ( Pulls?) on like a breeze, so lightweight, easy to understand and move around. I finished my lawn fairly quickly. Upon trying it out my hubby now wants to use it constantly. Very easy to set up out of the box, took me less than 10 minutes to get it going. I will update if need be, but for now, I love my purchase. Hoping it will motivate dear hubby to mow more often now . ... show more

  • Self propelled works well
Style: 22in 150CC Self-Propelled
So far, so good. I have had this mower for about 4 months now and its working good. My property is uneven and bumpy and the self propeller works well.

  • Hard to turn.
Style: 22in 150CC Self-Propelled
This mower cut the grass effectively. It does not like to be turned or guided. The powered rear wheels easily spin free on slightly wet grass. It will climb stones or bricks into flower beds or other places where the blade may hit durable objects. The grass bag will easily overfill, and when full, the self-propelled mower becomes a push mower. I would avoid this mower unless you are strong and want a workout. ... show more
