  • Great!
Style: 21 Inch-140cc
Couldn’t ask for a better push mower! Opened the box, put everything together which they made very easy to do and it did not take long. Put the bottle of oil in and put the gas in and it started immediately with one pull of the string! Been using it for a month now and no issues. You can’t go wrong with a Briggs & Stratton engine. What a good find!! ... show more

  • Great little mower
Style: 21 Inch-140cc
I really love this little mower! It comes nearly fully assembled in the box, the side chute for grass is easy on/off, it starts up well with the three fuel pumps and just one or two pulls. Wheel height is easily adjustable, too. No complaints!

  • Don't buy this !
Style: 21 Inch-144cc
Why did you pick this product vs others?: Appeared to be reliable, easily started, affordable, and lightweight enough to easily push as I am seventy this Dec. and wanted a new mower as my old one is difficult for me to push. My late husband usually did the lawmwork, but I must do it now. Mower quality: The lawnmower worked the first two times but now it either won't start at all, or is extremely difficult to start and then won't stay running. Very disappointing and it's too late to return I didn't even use it the first month it sat in the box in the kitchen. ... show more

  • Cuts beautifully!
Style: 21 Inch-140cc
Arrived a day earlier than expected which was nice. The included oil for initial fill was a nice touch. The deck seems solid overall and the large rear wheels are perfect for my property. That having been said, my initial experience was not without a problem. Started great and ran strong in very deep grass/weeds for about 40 minutes, then it started sputtering like it was low on fuel. It looked like there was still plenty in the tank, but I topped it anyhow. After pulling the cord about 12 consecutive times it finally started again and ran for maybe about 5 minutes before dying and not starting again no matter what I tried. Thankfully, I have good mechanical knowledge. After checking the spark plug I found no problem, the filter was perfectly fine as it should have been. Only next step was to clean the carburetor. After removing and cleaning the carburetor with carb cleaner spray only and reassembly, it took a moment to start, but ran flawlessly afterwards. I'm still not certain that the primer bubble is working as it should since the next day it took a moment to get it started, but once warm it started first pull easily. This is not a problem from Senix, the is a problem from Briggs & Straton. Sad that this is the case as I had higher standards from such a reputable US company. I will be contacting them regarding this Overall, I am happy with my purchase and grateful that it was at such a good price. Also for anyone who has trouble with turning a heavier mower, I feel this is a good option as it isn't too heavy and maneuvers easily. ... show more

  • Seems like good quality mower
Style: 21 Inch-140cc
Need a small mower to trim grass around hot tub where zero turn can’t go. Easy to start, big back wheels work well. Mulches high grass effectively.

  • Very easy to use
Style: 21 Inch-140cc
I ordered this by accident when my mower broke and I was unsure if it could be fixed. But super easy to put together and one pull and I was able to tackle my yard. It’s lightweight but tackled the high grass effortlessly

  • Great mower, great value for the cost.
Style: 21 Inch-144cc
Very good value for the cost. I'm a senior woman and appreciate finding a mower that is easy to start, easy to push/turn. The large back wheels make it a breeze to maneuver. I love the ease of raising/lowering the deck with built-in levers. The mulching option has my yard looking beautiful!!
