In this section, we’ll swiftly address some of the most frequently asked questions regarding gas lawn mowers.

How long do gas lawn mowers last?

We’re happy you asked. On average, the lifespan of a gas lawn mower ranges from eight to ten years, depending on how frequently it’s used. The average homeowner-level lawn mower can last for several years beyond the decade mark since their mowing tasks are generally less challenging. Also, by keeping your grass short, subsequent mowing jobs will cause less strain on the engine, thereby extending the lifespan even further.

Is it worth repairing a gas lawn mower?

That depends. If you’re handy around gas engines, you’ll want to see how extensive the damage to the engine is. The older the engine, the repairs it will need, and you just might end up spending more on repairs than a brand-new lawn mower. If you inherited your lawn mower from a grandparent, it might be time to replace it with one of the items mentioned on our list.

How tall a field can gas lawn mowers cut?

Excellent question. Gas lawn mowers typically have no limit. Their powerful engines are able to send the mower blade through patches of tall, thick grass without the slightest indication of choking or sputtering, unlike their electric counterparts whose mower blades can become bogged down in tall grassy fields. 

Can gas lawn mowers mow wet grass?

Indeed, they can. In fact, due to their minimal electrical components, gas lawn mowers aren’t just capable of doing so, but they’re ideal. Wet grass poses more of a challenge since it adds resistance to the mowing blades. A mower powerful engine will send the blades slicing right through wet grass without trouble.

What is the best month to buy a lawn mower?

The best times to find the greatest deals on lawn mowers are in April, May, and August to October. These times are right after the mowing season ends and when sellers are trying to empty their inventory ASAP. With the upcoming autumn season, it may be time to plan on which gas lawn mower to get.


There we have it, folks.

This guide on the best gas lawn mower should help you find the perfect model for your exact needs.
