    • Well built!
Size: 21 Inch-144cc Gas Mower
This mower gets the job done with ease. Took minutes to install the handle. The motor oil came with it and easy to install. Three pumps to prime and one pull to start. Great little push mower. Highly recommend!

    • Well worth the money
Size: 21 Inch-144cc Gas Mower
This is an excellent mower. Mine arrived with a small defect, and I can't remember the last time I had a more positive experience with a company's customer service department. This is the first Senix product I have purchased, but within the near future, based on my experience with this one, I will be replacing other tools with Senix products. The same quality (with way better customer service) as the brand names people have always been loyal to, for a MUCH lower price. It's worth saying again, Senix is get my a return customer. ... show more

    • Great value
Size: 21 Inch-144cc Gas Mower
Runs great. Cuts incredibly well. Light enough to move around even though it doesn't have self- propeller. I'll be curious how long it last. Right now out of the box I like it better than Troy-Bilt. Which are supposed to have great engines but my carburetor went South after 2 years.

    • Wouldn’t buy.
Size: 21 Inch-144cc Gas Mower
Ran amazing for almost two months and then quit middle of mowing and won’t start now. Waste of money, do not recommend. This was even with it being put up in a shed never left out in bad weather. 👎🏻

    • Well made and light weight while nicely powered and sized for the price.
Size: 21 Inch-144cc Gas Mower
Super Easy Set Up with no tools required. Seems to be well made while being lighter than older mowers. It is easily manuverable with the nice wheels sizes especially the larger set on the back that make turns and uneven lawns less work to navigate. Includes the required engine old for use. It's winter here where I live currently so I could not mow with it yet but did run it and it started easily. Just add the oil that's included and your gasoline and 3 pulls later mine roar d to lift. Priced retail at $299 its already a great size deck and higher engine output option compared to others in the same dollar bracket. At the time of my purchase it was on sale for $197 which made it a very impressive multching or side discharge mower compared to any other options similarly priced. If you are looking for the best gas powered mulching mower for around $200 dollars save yourself the search time and shopping and take one of these home. I feel it's a fantastic machine for the money. ... show more

It gets the job done, but the engine struggles a bit if the grass is slightly thick. Setup was easy, but the mower itself feels lighter and flimsier than I expected.
