Gas Lawn Mowers

Gas lawn mowers can prove to be quite messy. Another disadvantage associated with gas lawn mowers is that as soon as the gasoline runs out, you have to travel for the purpose of buying more. An alternative to gas lawn mowers is electric lawnmowers.

However, a large number of people do not prefer these because of the presence of cords and they can get in the way. Those lawn mowers that use cords can also cause severe injuries.

A majority of rotary push mowers are operated with the help of internal combustion engines. These internal combustion engines are either two-stroke or four strokes and usually run on petrol or other fuels. Such gas lawn mowers usually have a single cylinder.

The horsepower is usually two to seven on an average. Such engines are mostly carbureted and require a manual pull to kick-start them. However, a large number of brands offer gas lawn mowers that have an electric start. A throttle that helps to decrease or increase the speed of the engine was offered in the past.

However, more recent gas lawn mowers have a throttle that is pre-set that adds to the life of the engine.

Gas lawn mowers also store fuel as well as transport them which can prove to be quite disadvantageous. Those gas lawn mowers that are two-stroke require a mixture of a particular type of fuel or oil.

The major disadvantage of gas lawn mowers is the emission of pollution. These include ozone precursors, polycyclic aromatic hydrocarbons and carbon dioxide- all of which can prove to be extremely harmful to the ozone layer.

Those gas lawn mowers that are four-stroke tend to emit polycyclic aromatic hydrocarbons.
According to a number of sources, if you drive a car and a gas lawn mower for the same amount of time, more pollution will be emitted by the lawnmower.

Using a gas lawn mower for about an hour was found to emit at least 26 different varieties of polycyclic aromatic hydrocarbons. It also emits benzo[a]pyrenes which are also present in cigarette smoke. Chemicals such as carbon monoxide, methane, nitrogen oxide, hydrocarbons, and smoke particles are also present in the gas emitted by gas lawn mowers.

Gas lawn mowers also emit ozone. Those hydrocarbons that are emitted by lawn mowers mix with the nitrogen oxide when sunlight is present and leads to the production of ozone. This danger is escalated during summer time as the sunlight is the brightest in those months and lawns are mowed on a more regular basis during summertime as well. Ozone is an element that tends to settle along the lining of the lungs and leads to an increase in asthma as well as other breathing problems. The “Red Alert” that is created during the summer months is usually due to the presence of ozone in the atmosphere.

According to a study, the most amount of pollution is emitted by gas lawn mowers and other such garden types of equipment. This percentage is increased in suburban and metropolitan areas wherein lawn mowing is carried out more regularly.

According to other studies, using a particular kind of catalyst can lead to a reduction in the number of pollutants that are released into the atmosphere. Naturally, the best alternative is switching over to cordless lawn mowers or cordless electric lawn mowers that run on batteries and are much more environmentally friendly.

Noise pollution is also emitted by gas lawn mowers which further adds to the pollution in the air. Noise pollution can lead to a number of problems such as anxiety, hearing problems as well as a loss in concentration and can also lead to insomnia.
