Honestly, this mower did way better than I expected. My grass was pretty overgrown and I thought it might struggle, but it handled it like nothing. It cut through thick grass super easily and didn’t get bogged down at all. The lawn came out looking really clean and even, and it’s really easy to use. It’s also super easy to maneuver, especially with the self-propelled feature, it makes pushing it around way less work and a lot faster. Overall, I’m really happy with it. It did an amazing job and made the whole process quick and simple. Definitely recommend if your yard gets a little out of control like mine 😅

Works great easy to use and set up. Not super heavy, so far seems durable.

The only good things I can say about this mower is that it comes almost completely assembled with the motor oil included. And it’s a pretty blue. Other than that it’s a piece of junk. I had difficulty starting mine right off the bat. It took multiple pulls on the power chord which required a lot of strength because the chord seemed to keep getting stuck. Every time I had to stop the mower then start it again I went through the same misery…15-20 pulls before it would start. In addition, I set the cutting height to my customary next-to -the-lowest setting and it immediately began to vacuum up the soil on my lawn and blow it out the side discharge with alarming velocity. I’m talking about huge clouds of soil that blew out and covered everything in the vicinity—including me. My lawn was not dry either—it had rained the day before. I NEVER had a lawn mower do that before. It almost seems like the engine has too much power for what it’s made to do. I managed to get my back yard and side yard mowed but then while I was mowing my front yard, I began to hear what sounded like something made of metal knocking around inside the mower. The next thing I knew I heard a loud “Pop!”, The mower shut off and I’ve been unable to start it since. I think it’s dead. I’m so bitter and angry about this because it’s too late to send it back and I still have more payments I have to make on it.

Showed up quickly and I was cutting the lawn with it 15 minutes after opening the box. Someone who didn't read the instructions could have done it in 5 minutes. It cut smooth and even, managed about 1/2 an acre on one tank of gas, and was able to cut an over grown backyard with grass as high as 18 inches. I cut a solid acre in an afternoon, only limited by my own stamina. My riding mower is on the fritz and I needed something cheap to fill the gap. I ordered on Monday, had by Wednesday, unboxed and mowed on Saturday. If you wanted a bottom of the line side discharge, this is a good one. No complaints. I think it will serve me for years as small space and back up, or even the acre.

Easy to assemble very reliable starts every time can take a lot of abuse Too bad I cannot find any lawnmower engines available. You have to buy the whole lawnmower, even though there’s nothing wrong with the chassis I have large property and sometimes I will hit a rock or something, and if the blade hit it real hard, it screws up something with the driveshaft in the engine. I usually have to buy a new lawnmower every two years because of that.

Works great. No problem cutting my lot and a half of grass. The RPM may need to be set down a bit. The gas tank seems to be larger than my previous self-propelled mower and I go through fuel faster. But hardly any clippings stick under the deck after finishing mowing. The mower starts well first thing but cutting the engine while mowing to move a downspout makes the engine hard to start again. The handle that raises and lowers the deck is for all wheels at once on the right instead of on every wheel. That makes it easier to mow along a chain-link fence on the left because there are no handles to get caught in the fence on the left. I use the mulching mode so far. I am on the 4th time cutting my lawn with this mower as I write this.

So far, the mower has been very good and performs as expected. In my opinion, the product itself is good. The only negative point is the user manual. The letters are extremely small and there is too much information packed together, making it difficult to find the important maintenance instructions. Most of the useful maintenance information I actually found on the internet instead of in the manual. For the initial start-up, I added oil to the crankcase and fuel to the tank. The manual recommends pressing the primer bulb 3 times, but after trying many times without success, I found a YouTube video where someone recommended pressing it 15 times. After about 12 additional presses, the mower finally started. I also performed the first oil change after the initial 5 hours of use, as recommended. The oil came out very dark, which confirmed to me that the early oil change was important. So far, my opinion is positive about the mower itself. The weak point is definitely the user manual, not the product.

The mower was delivered missing one of the handle bolts. I called Amazon support, and they were very helpful. They gave me a partial refund and a contact number to call and an email address to Senix support. Senix support was terrible. They did not answer any of my calls or emails until 10 days later. Then they said they required all kinds of documentation, pictures and a lot of red tape, when all I wanted was for them to send a handle bolt. In the mean time I bought a handle bolt and it works fine. The lawnmower itself seems to be fine, although it start a lot harder than what had been described, maybe after 8-10 pulls. The last time a mowed it was only 3 pulls, so maybe it is getting better.
