Choosing a lawn mower depends on your yard size, terrain, and how you handle clippings. Gas mowers offer unlimited runtime for larger lawns, while cordless electric models provide quieter, emission-free operation. Riding mowers suit properties over half an acre. Our comparison covers push mowers from A-iPower and WEN, plus a Greenworks riding mower, to help you find the right fit.

How we chose these
- Power source and runtime: Gas engines run as long as you have fuel; cordless mowers are limited by battery life and recharge time.
- Cutting width and height adjustment: Wider decks cover more ground per pass; more height positions give finer control over grass length.
- Clipping management: Options like bagging, mulching, or side discharge affect lawn appearance and cleanup.
- Yard size suitability: Push mowers work well for small to medium lawns; riding mowers are better for large areas.
All mowers in this comparison are push models except the Greenworks riding mower.

- For cordless mowers, check the battery runtime and coverage to ensure it matches your yard.
- Gas mowers need regular maintenance like oil changes and air filter cleaning.
FAQ
How do I choose between gas and cordless mowers?
Gas mowers run as long as you have fuel, but require fuel and regular maintenance. Cordless mowers are quieter, emission-free, and easier to start, but are limited by battery life.
What size mower do I need for a 1/4-acre lawn?
A mower with a 19- to 21-inch deck and sufficient runtime, like the WEN 20839, can handle up to 1/4 acre on a single charge, according to WEN.
Can I mulch with all these mowers?
Only the A-iPower LM3N1-HWP10 and LM2N1-HWP, and the WEN 20839 offer mulching capability. The A-iPower LMSD1-LWP-B is side-discharge only, and WEN lists only bagging for the 20835.
How long does it take to recharge the batteries?
Greenworks states the CRT4262 batteries recharge in 3 hours. WEN does not specify recharge time for its mowers.
