Mowing can be a family affair!
This lawnmower was very easy to put together, it cuts the grass just perfect and has great power. This is a gas mower and does not require battery charging. The noise is medium but not too loud to irritate neighbors. The size is perfect for my kids to also mow.

Good little mower
This mower only took a few minutes to put together. Iâve only used it twice so far but it starts right up and does a great job of mowing!

Value, value, value
These mowers are a great price. This one at 144cc ($199) and another at 125cc ($239). No clue why the bigger engine is cheaper.Iâve bought both models. I mow a three acre graveyard with about 800 memorial stones. Fir the open arras I use a comercial Scag 48in zero-turn.For very tight places and along the bottom of the stones an Echo weed wacker.These push mowers are used in space20â or wider and cut a margin in front of each long line of stones. Thus, an effirt to keep the big and heavy Scag from hitting and knocking over the gravestones. A system that works.The weak link is the push mowers. In and out between the graves produces torque strain on the wheels, the steel body, and the bolted connection of the engine to the body. Things begin to rattle quick. Mr. Homeguy may use these an hour or so per week and no gravestones to work around. I use tgese six hours a day for two days a week in cutting season. I am lucky to get a yearâs service bc efire wheels/ engine mounts/etc. fall apart.Iâve tried $500 & $600 Hondas and John Deere. They donât kast any longer.So I use these, the cheapest I can find and use them up. Along the way they cut just as well as ones twice or three times more costly..

instructions don’t say where to put gas and oil and it’s not labeled on the mower
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.

Killer lawn mower!
This is an awesome lawn mower! I’m very picky about lawn cutting material. This brand is top of the line. If I bought it at Lowe’s, it would have been $75 more! This brand is not even sold at home Depot.Yet another wonderful buy from amazon!

Working great.

Not put together at all.
I probably did not read good enough. Beware this lawnmower is not put together. no part is attached. You have to put it all together. Iâve looked up the same lawnmower on different sites, and some of them had at least the arms on them.
