Very powerful . Impressive for cost

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!

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.

So far, so good. I bought this at the end of the season assuming that the prices will be higher in the spring. I tested it mowing half of my yard before stowing for the winter (always run the gas dry between seasons). It worked fine (only used side discharge). Longevity remains to be seen, used my last mower 21 years. Assembly instructions poor (the blue lever goes on top with right cable attachment for Run, black lever underneath with left cable attachment for Drive). Adjust the drive lever cable so that it engages with the lever closest to the grip to make it easier to engage/disengage. Saw comments about being too fast and too slow -- seems fine to me. Just release the Drive lever when turning. Even so, depending on the grass, it doesn't grab particularly strong into the lawn so if you hold the mower steady the wheels can slip without releasing the Drive lever. I'm used to front wheel drive which is easier to control but this seems okay. Saw comment about the pull cord being too long: maybe it is, but no trouble starting. First time after filling oil/gas started on third pull. Then with engine still warm starts with one half-hearted pull (as expected). When finished there was a lot of fine detritus at the rear bag location -- I blow it clean top/underside with leaf blower after each use. Posting now because I wouldn't purchase a mower which had no reviews.

I love this product. I love the design. I love how compact this mower is and I love the color. This is a great investment for me, especially since I have a small front lawn and a big backyard. Most of my concern comes from my front yard and it handle it with E thank you.

This is a terrific low-end, but highly efficient mower. Easy to assemble and operate. It does an excellent job on carpet grass.
