I bought this mower a few months ago. Assembly was a breeze! 15 minutes max. It includes all of the attachments for side discharge, bagging, and mulching. I added oil and gas and off it went. The walking pace is slow enough for a good cut and fastest enough to get the job done. Our yard is pretty tough and this mower cuts it no problem. So easy to operate. No choke, no throttle, no primer build. Just pull the cord and go. Yes I would buy this mower again.

I have used about 2 times since purchasing, so far it was been great! Starts up on first pull every time. There is only one flaw to the lawnmower, not really a big deal, but the self propel lever is on the under side of handle while the top one is to keep it started so it’s kinda weird but something I def can overlook and deal with at this price point and how well it works. Also just a heads up, I knew it would be this way with it being rear wheel self-propelled, is that when you u-turn it after going straight to do the next parallel line it does giddy up really quick when using the self propelled bcuz you are lifting up the front wheels so make sure to not have the self propelled lever down. Other than that great machine cuts great and I like that it has 2 levers 1 for keeping it started and 1 for self propelled in case self propel stops working you can still use it like a normal push lawnmower something I was unable to do on my last Toro lawnmower that was way more expensive.

I regret buying this lawn mower. It arrived three days ago and I still have not figured out how to use it. First, do not buy this lawn mower if you have never owned a lawn mower before. Second, do not buy this lawn mower if you have never put a lawn mower together before. In no part of the listing nor in any part of the instructions does it tell you what tools you need. Before buying this I did not own the needed tools. You will need a 10mm socket wrench and a 13mm socket wrench and a crescent wrench to assemble this. a second 13mm socket wrench with a second handle will help as well as a 12mm socket wrench with that same second handle. I did it with just the 13mm and the 10mm and the crescent wrench. Make sure your crescent wrench can open up to 13mm. I attempted to borrow a set of American sockets from a friend but they didn't fit so I had to spend $25 to buy a set of metric socket wrenches on Amazon as Walmart had none and Home Depot and Lowes had only expensive sets (both over $50). So that took me two days of going back and forth trying to figure out what tools I needed. It would have been so helpful if they only had listed those items with the advertisement so that you are prepared. I had no idea what size sockets I would need so I ordered a 3mm to 13mm set and found out by trial and error. I could have just purchased the two size sockets individually had I known ahead of time the size I needed and done that for $10 but their lack of consideration cost me the extra $15. I recommend doing this on a patio table or some such as that will make it easier to install the wheels. But you can do it on a garage floor or driveway. Unfortunately the instructions are in very tiny writing. I am a senior citizen and I had to combine 2.75 dptr reading glasses with a 3X magnifying glass to read everything. the diagrams are also quite tiny so it is difficult to see. There is no clear picture of what screws you have to use on what part. I learned by trial and error. Total assembly time once I had the tools was two hours. I have never put together anything mechanical. If you have experience putting lawn mowers together and have a more extensive set of tools you will probably do this in less time. Now for the reason why I have not yet used this lawn mower. The instructs are incomplete and and are ONLY designed for people with experience using and maintaining lawn mowers. If that is not you then you probably should not get this lawn mower. In absolutely no place in the instruction manual, box, on the listing, in the one video that accompanied the listing or anywhere on YouTube could I figure out where the gas or the oil goes. Now this might seem obvious to anyone with experience using lawn mowers. But despite being 65 years old, I have never until now attempted to use a lawn mower that had a motor in it. My old one was completely manual and it just couldn't do the job. None of my immediate neighbors speaks English and my friend who loaned me the American wrench set does not have a lawn and knows nothing about lawn mowers. It would be nice if at least it was labeled on the lawn mower itself but it is not. So I am taking a risk. If I put the oil and the gas both in the wrong place I think I will probably ruin the engine or perhaps start a fire. Now if you have lots of lawn mower experience this might be a good deal for you. But I could not tell you since I have not yet figured out to how to get it going as there is no oil and gas in it yet. I absolutely cannot recommend this lawn mower for the above reasons.

It was the cheapest gas lawnmower I could find seeing as my battery powered one just couldn't cut it literally. I don't prefer gas but it works well. Finding a cheap blade to replace it is a different story though. I can get one from the company but it costs almost double when I can find it through a third party for cheaper. Took a bit to put together and that wasn't fun but not hard. Have to undue bolts at the wheels to adjust the blade height that's a pain and lost ya a star but other then that it's good.

I’ve used this all summer and it’s been great! Great price and a great product. Took 10 mins to set to and get gas and oil and was ready to mow!

I bought this mower to replace a new Powesmart mower which was absolute JUNK (proudly made in the USA & the worst customer service ever!). Fingers crossed this mower holds up, so far so good. It starts up on the first pull and does a great job of cutting the grass. Yeah, it’s kind of a pain with respect to adjusting the wheel height but I don’t care about that. I need a mower that won’t break after the first time I use it. I like the color too!
