Great Mower
Great mower not really as loud as others, perfect speed for an older person as myself (63). Cuts perfect very easy to assemble. Very light,self propelled works great

Hard to find parts
This worked great for 2 weeks then the propulsion belt broke. I love this lawnmower, however the issue is finding parts. This doesn’t have a manual with it and it’s hard to find exact parts. My biggest issue with buying these lawnmower is maintenance, this company didn’t not make it easy. If you aren’t mechanical inclined don’t buy this lawnmower. ... show more

Almost 5 Star
I have a large property and I needed a mower for areas that are too small for the tractor and too big for the string trimmer. This is a surprisingly decent mower for the price. Starts on 2 or 3 pulls, cuts good and RWD is a plus. Plastic deck. My ONLY gripe is the grass bag. Under dry and dusty conditions, you Will be covered in dust and dirt due to the loose weave of the bag itself. I'll have to modify the inside of the bag so it lessens the dust storm. If I even get a few years out of it, it's still half the price of well known names. The manufacturer needs to tighten up the fabric on the grass bag. ... show more

Shaky lawnmower
I usually don’t write reviews, but I had to especially about this lawnmower. The lawnmower is okay. Came very quickly after placing the order. Setup was simple enough and after putting oil and gas I cranked it up. I like my grass to have a clean cut and I always bag the grass. Dumping the grass from the container was a problem. The opening is too narrow and I was shaking the grass container like there’s no tomorrow. The self propelled handle is at one speed. I was literally running behind the lawnmower. You can’t control the speed from slow to fast. The wheels don’t have traction. Sometimes the back wheels just spins on the grass. Sometime when I start the lawnmower it would back fire. You would hear a sound like a gunshot. I thought the lawnmower was shooting at me. I’m a Honda lawnmower guy, unfortunately they stopped production of lawnmowers. I will get in touch with the manufacturer of this lawnmower and explain about the backfire. Now it’s about my safety and people around me. ... show more

HORRIBLE
Well, my fault for buying cheap made in China! Worst push mower ever!! The self drive cord broke. Doesn’t handle thick grass or even grass that’s not thick. Back breaking mower!

Cutting and self propelled
Well worth every penny. Cuts great and the self propelled feature is awesome. Didn't take much to put the handle together and get to mowing.
