Style: 8-Positions Cutting Height
I was kind of hesitant to buy this mower because of some bad reviews, but the mower I got works great. It has a more powerful motor 144cc than my previous mower 125cc and at a lower price. It was easy to put together and it came with oil. it started right up and cut the tall grass easily. I heard complaints that it was too load, but it didn't seem any louder than my previous mower. Still, I just got it today so I can't say how well it will hold up. the only thing I saw wrong with it is that the height adjustment keeps slipping; It doesn't look like something that difficult to fix but I just used a tie wrap to hold it in place because I don't plan on changing the height once I set it; but technically that is a legitimate issue.

I got this to replace my old mower that I bought 20 years ago from the local hardware store when we moved into our house. I was pleasantly surprised by the quality of this mower and appearance. Only required some minor assembly and engine oil was included in the package. Height adjustments are easy to make and everything is clearly marked. The engine starts up with one pull and runs flawlessly so far . Seems like a quality machine all around and luxury compared to my old one in its best condition. I feel spoiled using this one . It’s so easy to use and powerful . Highly recommend !

Unpackaged the mower and everything looked good. Upon first start it seemed to vibrate more than I was use to. After the first use I inspected the blade and noticed the drive shaft from the motor was a bit off center causing the blade to vibrate the whole motor assembly. After about 2 hours of use the plastic motor cover vibrated off. The screws holding it in place were threaded into plastic and completely stripped. After trying to fix that the exhaust cover was the next to go. Then the plastic dip stick assembly started to shows signs of cracking. After another 2 hours of use the whole plastic dip stick housing cracked and began leaking oil. I was desperate to make this mower work but by now zip ties and JB weld were holding together a mower with less than 8 hours of use. The grand finale was the whole plastic dip sticking house broke off spraying oil into the air and all over my leg burning my calf. I should have returned the mower after the first use. I run a small non profit community garden and was determined to make this cheap motor work. I wanted to believe it could get the job done. I was wrong. I am now left without a mower, out the money spent on it, and nursing a burn on my leg. I could assume the only problem was that it was defective and sent with a bent drive shaft. If you have to purchase this mower make sure to inspect it before using it for the first time and return it if anything seems wrong. I would be happy to be proven wrong and that this single mower was defective from day one. Until I am proven otherwise I can not recommend buying this mower. It is poorly built and even worse clearly safe.

Five stars because it starts every time on the first pull, cuts great and is powerful. Started to give it four stars because the wheel fell off while I was mowing my lawn for the first time. Luckily I was able to find a small plastic part in the grass and by looking at the other Wheels in 30 or so minutes I had repaired it. The wheels come pre-assembled on the lawn mower. But all the rest has been great. Starts the first time, comes with oil, looks great, runs well and cuts grass great. Great value as well. Lately it's been rare to find a mower that starts and Mows so well. So yes five stars even though a bit of a wobbly start with the bad wheel.

The small plastic recoil guide wrap around and clips to its self. And repeatedly opens allowing the recoil rope to end up back at the engine. Since the safty bar must be held against the handle bar mowing stops until that annoying clip and cord are all brought back together. The good: Started easily, unless pushed too fast into 18" vegitation. Plenty of power (not a brush hog). No choke nor user controlled throttle. Blade was checked for balance and was acceptable. Ball bearing wheels, 21" cut, user pushes. Used blue thread loc assembling the handle bar. About one hour oeration, 201cc.

WOW! Figured I'd take the time to write a real review since bot reviews are so common...first off, the box that it came in is high quality. Complete with brand, logo etc. Good sign already NOT some generic blank box with Chinese on it. Assembly EZ PZ. 13mm and 10mm is all you need. 6 bolts. Mime however was missing the 2 screws for the chute. No biggie I have tones of screws. The Manual is a Chinese to English translation...so expect some, issues. This mower takes 10w30 not 15w40 like in the Manual The engine is nice it's on par with predator. It's just a generic branded 170cc Chinese motor. Basic and simple The height adjustment is brilliant! The cons: It's loud, not an issue for me but some places it MAY be. The engine brake lever is an arm work out, again not an issue for me but it is something that should be noted And the only real con is the chute is angled straight out. So rocks and sand get shot out just be cautious! Will this mower last 10+ years? Who knows but for a cheap get me by mower it's perfect!

I selected this mower because it was simple, a push mower, had a large displacement engine (201 cc), and a relatively large gas tank. It arrived in a timely manner in a cardboard box and was well packaged. All I had to do open the top, cut off one side of the box (easy to do with utility knife), and roll the mower out the open side onto the floor. Assembly was easy Assemble the handle and attach to the mower according to the instructions and images. Add engine oil (an absolute must) and gas. Then three pulls on the starter cord and the mower came to life. Today, I used the mower for the first time on my front and side yards. I checked engine oil. Then, three pulls on the starter cord and the mower was running. The grass was a little high but the mower plowed right through it. This mower has plenty of power and, with the large gas tank, I may be able to mow my entire lawn without adding more gas. So far I think I made a good choice.
