Not worth the price!
Well! I wish that I could say that this was a great purchase but I can’t! First of all it is very loud. Secondly it is hard to control because it uses rear wheel drive. Thirdly, the materials that the mower is made of looks cheap and fragile. Finally, the self propel control reaction is too torqued which contributes to control problems. ... show more

Beast of a mower
Have had mine for nearly a year. Have no had a single issue. Mows through pretty thick St Augustine grass here in TX. I run it for a total of a 80 minutes each mow and she powers goes. Fairly fuel efficient as well. Very happy with this mower.
Reviewed in the United States on August 5, 2026 by These came in perfect condition and the seller was so attentive throughout the shipping process. Liam checked on us afterwards to ensure it had been delivered in good quality! Amazing service and product, I cannot wait to use it!! The colors are precious and so easy to use. As stated, they do not bleed through either! I’ve been using them every day since I got them and I love them!!! HIGHLY RECOMMEND. 🫶🏼

Efficiency, power and starts easily
Only thing that bothers me is that the self propel is slow. I can walk faster. Starts on first pull. Tears through everything. Cushioned handlebar. Great lawnmower. No disappointments. Just slow.

Don’t waste your money
Most horrible lawnmower I’ve ever owned. Had a hard time starting it up the first time. The next weekend went out to do the backyard and it wouldn’t start. Brand new lawnmower and it won’t start. Don’t waste your money.

Fantastic mower
This is an old school lawnmower. There's nothing fancy about it. Big engine, heavy, good self propelled and cuts through anything. Everything is steel and it just works. I love mine. It's not a $700 Toro and it's about as simple as it comes and in this day and age simple is better.

Broken after TWO mows!
I knew I shouldn't have gone with a bargain brand, but here we are. I used this TWICE and fuel started leaking out of the front of the engine, presumably from the carburetor. And of course it ran down underneath the concrete in my garage and now my entire house smells like it is going to explode. I called the company and they said they would send me a new carburetor, but I'm not 100% sure that's even the issue. So they said to return it to Amazon, which you can't do because it had gas in it. Thankfully they still refunded it. ... show more

stick with name you can trust
Very first time using it and the back flap snapped off. The oil dipstick popped off somehow and oil started spewing out while operating. Looking to replace this as soon as possible.

Heavy
That's it is rear drive not front wheel drive. Takes time to learn to operate it.
