  • Great lawn mower
Size: 21 Inch, Self Propelled
Great lawn mower my other lawn mower broke about 2 and 1/2 weeks ago and my grass was long and it cut right through it very easy to assemble works very well one pull start time a lot of power speed not too bad self propulsion just right

  • Absolutely the best self-propelled lawnmower for the $$$$$$
Size: 21 Inch, Self Propelled
Best self-propelled lawn mower for the $$$. Period! Assembly was easy after watching YouTube videos for help with the clutch handle and run/off handle. What I like: Solidly built, no rattling and the handle is exactly the right height for a 6' operator. Power for days with the 210cc engine. No bogging down in thick Burmuta grass. Tank has large capacity! Easily able to get through two mowing iterations with one tank of grass. Came with clear instructions and 10w40 oil for the crank case. Also a spark plug removal/install tool. Package was sound and product was well protected. Contact phone number for issues was available. The speed while not adjustable is, in my opinion, perfect. Once you get the hang of rear wheel drive, mowing is almost effortless. Just similar to walking. Side discharge if you like and rear bagging. I use neither and mulch my grass, returning the nutrients to the soil. Dislikes: Absolutely none. Happy customer, solid purchase! ... show more

  • Gets The Job Done
Size: 21 Inch, Self Propelled
In many respects this was a downgrade from my previous lawn mower but it does have some nice features. Shipping arrived on time and the item was packaged well. The instructions are not very well written so assembly can be a little difficult. Used the lawn mower with rear bagging for the first time today and it did a good job. Here are some of the pros and cons from my first experience. Pros : 201cc engine which is very powerful and easy to start The 8 position wheel height adjustment is very convenient and works well The discharge selector (rear/side) does a good job of directing the flow of the grass clippings Creates a fine mulch when bagging or mulching grass Cons : The 201cc engine is not Briggs & Stratton The angled handle is difficult to get used to and there is no adjustment to raise/lower the handle The angled handle makes using the start/self-propel levers awkward to use (takes time to get used to them) The grass catcher bag is small in comparison to other mowers that I have owned The self-propelled feature is single speed and slow (I'm 5'9" and 68 years old) There is a wash out port installed on the mower deck but no adapter to connect it to the garden hose. Checked for an adapter online and there is nothing available (even from the manufacturer) ... not sure why it's there Overall, this a good lawn mower for the money. The rear wheel drive takes a little getting used to but the lawn mower is strong, easy to use and does a good job cutting grass. Update concerning the deck wash kit. You can purchase the Deck Wash Quick Connect (available on Amazon) which will fit the wash out port on the lawn mower. Be prepared to get wet ... the water is directed straight down and sprays everywhere. My solution was to purchase the Deck Wash Cleaning Adapter (also available on Amazon), enlarged the hole for the wash out port to 5/8" and install. Works perfectly. ... show more

  • Small but Mighty
Size: 20 Inch, Hand Push
Tough little mower! My riding mower broke and I needed something to get me through to the end of the season- I put this mower to a pretty extreme test mowing my overgrown back yard in the early morning while still wet with dew. It did a great job! The little mower that could!

  • LOVE this lawnmower, but there are issues - Review revised update as of 08-16-25
Size: 21 Inch, Self Propelled
08/07/2025 - This is one of the best lawnmowers that I have used in a long time. It has a lot of power and if you are not careful, the speed of it will pull you like a run away dog...LOL Very easy to assemble and I believe it was worth every penny I spent on it. For a push more, it is very easy to maneuver. Revised update as of Saturday, 08/16/2025 - the more I used the mower, the more I started having issues with it. The belt for the self propell kept coming off. My grass wasn't high, but it is very thick grass, so it kept choking and cutting off. ... show more
