Best Gas lawnmower 2021 Buying Guide

This list of things to consider will definitely help you choose the best gas lawnmower according to your requirements.

Swath size

The swath size in gas lawnmowers ranges from 20 inches to 24 inches in width. The wider the swath size the larger will be the deck size. A large cutting swath will mean only a few passes to remove the grown grass from your yard.

So make sure you choose one with a large cutting swath. A size that exceeds 24 inches may be inappropriate for a household as it will have a bigger engine. This will make the entire machine heave, thus disabling ease of movement.

Engine size and type

As we saw earlier, the engine size entirely depends upon the size of cutting swath. There are two types of the engine generally used in lawnmowers.

They are two-stroke engines and four-stroke engines. Just like it sounds, the four-stroke engine is very much powerful than two stoke engine.

However, such massive power not required and many people own two-stroke engines only. You can select a mower with larger power if you have a very big yard with thick grass.

Large engines also add up to the weight so make sure you get a self-propelled model. Small engines are light, easy to control but they don’t cut thick grass effectively.

Grass clipping management options

Collecting the grass clipping as you trim your lawn is very important and is essential. Many mowers are available with multiple options for grass clipping but these need to be bought extra.

They come with a single option of collecting the clippings in the side and later disposing of them. This is an affordable option.

Otherwise, you can use a bag to collect them. Another option is to mulch the grass periodically as you are mowing. This is a good way to keep your lawn healthy. The choice is yours and you can select the option that is very suitable.


The mechanical parts can be replaced when they are damaged but not all spare parts are available in the market. You need to take good care of these gas lawnmowers after your work is done.

That is you must remove the gas and then keep the mower covered from sunlight or rain. These measures are a must to make this equipment serve for a long time.

So look for good quality gas lawnmowers that can cost you less for maintenance. Also, make sure if most of the spare parts are available in the market before buying.

Safety features

Along with the safety features, you need to check the height adjustments also. Your yard might grow grass at any height until you trim them, so easy height adjustment is a must.

It is recommended that you don’t cut the grass too short (below three inches), so a good gas lawnmower should give height adjustments from at least two inches to six inches.

Safety features like child-proof mechanism, prevention from rocks or sharp objects as you move. Automatic stopping of blades is also a safety feature that you can look before buying.
