Customer Reviews
Customer Review: “Great mower for a small yard! I picked this up in early 2024 for $220, and it still looks like it’s the same price. If you don’t want to pay extra for cordless, or, like me, don’t have a good place to charge the battery, this is nice for small yards. Make sure to research the proper gauge extension cord if you go this route.”
Customer Review: “Impressed with this powerhouse of a mower. Didn’t think it could handle the jungle that was my yard. Hadn’t mowed in two years. Blackberry vines were taking over. 2-3 foot tall grass was reforming the prairie back there. Small saplings were becoming real trees, magnificent redwoods even. This mower handled it all!”

Customer Reviews
Customer Review: “Surprisingly fantastic! I ordered this as a backup until my rider parts come in. My grass was long enough the cops stopped by to tell me to cut it! I got just over half my yard done on the first charge but let me say that the bag was STUFFED after just 3 passes across the front of my yard (about 90′). It handled my thick centipede grass like a champ.”

Customer Reviews
Customer Review: “I had been wanting this style mower and had tried out a different brand that someone had, and I could hardly push it. I don’t think it was that much heavier than this one, just not geared as smoothly. The Wirecutter recommendation site liked this one and then my brother bought one and I tried his and it was easy to push, so I bought one.”
Customer Review: “I have a small lot (~ 50′ X 100′) that I have been mowing using a battery powered electric mower. I have a long history of problems with gas powered tools, so I switched to electric 10 years ago with OK results. Well, my electric mower died (motor was shorting out) and I didn’t want to put more money into a mower that just cuts grass. I decided to go back to basics and get a reel mower. I’m glad I did!”

Frequently Asked Questions
Q: What is the best engine size for a 20-inch gas lawn mower?
A: For a 20-inch gas lawn mower, an engine size between 140cc and 160cc is generally sufficient for most residential lawns. This provides enough power to cut through most grass types without being overly heavy or consuming excessive fuel.
Q: Is a self-propelled mower necessary for a 20-inch gas lawn mower?
A: For a 20-inch cutting width, a self-propelled feature is often beneficial, especially if your lawn has inclines or you prefer less physical exertion. However, many lightweight 20-inch push mowers are easy to maneuver, so it depends on your lawn’s terrain and your physical condition.
Q: How often should I maintain my 20-inch gas lawn mower?
A: Basic maintenance should be performed at the beginning and end of each mowing season. This includes changing the oil, replacing the spark plug and air filter, and sharpening or replacing the blade. Regular cleaning after each use is also recommended.
Q: What are the advantages of a 20-inch deck size compared to smaller or larger decks?
A: A 20-inch deck is a great compromise. It’s more efficient than smaller decks (like 18-inch), allowing you to cut your lawn faster, but it’s also more maneuverable and less cumbersome than larger decks (like 22-inch or more), making it easier to navigate around obstacles and store.
Q: Can a 20-inch gas lawn mower handle tall or thick grass?
A: While a 20-inch gas lawn mower with a strong engine (140cc+) can handle moderately tall and thick grass, it’s always best to mow regularly to prevent overgrowth. For very overgrown conditions, you might need to make multiple passes or consider a mower with higher power or a wider deck.
