If you're shopping around for a straightforward, no-nonsense lawn mower, a manual gas model might be the way to go. A self-propelled mower can be a nice luxury, and cordless electric options are worth considering, but it's hard to argue with the marriage of power and simplicity. If you're looking for the safe choice, Walmart has a terrific Flash deal on the Senix 21-Inch Four-Cycle Gas Lawn Mower. Normally priced around $399, it can be yours for just $249.

This walk-behind mower sports a 144-cubic-centimeter, four-stroke engine; a 21-inch steel deck; and all the versatility and maneuverability you need to tackle the vast majority of lawns. Choose from six different height levels, and swap between the mulching function and side discharge to suit your lawn-care preferences and the length of your grass clippings. The Senix features 11-inch rear wheels and 8-inch front wheels. It comes with a two-year limited warranty.

"It didn't take long to put it together," wrote one reviewer. "Once everything was set up, I put the oil and gas in. It took more than three presses to prime it, but once it got going, it ran just fine. Cut the lawn — mostly tall weeds and flowers — with barely any effort on my part. The lowest height setting cut it to the dirt."

"Light but powerful. Get one," another shopper said. "This mower does a great job; it's light, it mows great, and my back thanks me when I have to lift it into my truck. Also, it runs fairly quiet for a gas mower, but doesn't struggle in terms of power. I've never had to press the primer; it starts right up on the first pull. If you keep up with your yard and don't let the gas get three feet tall, I think most people will love the Senix for its light weight."
