Types of Lawn Mowers

There are two kinds of lawn-mowers, the electric-powered and gas-powered, its type derived from depending on how they operate. Another feature you should know is the engine of the machine. It could be two-stroke or four-stroke. The latter is more fuel efficient but may produce more noise compared to the two-stroke. These are worthy of consideration before buying one.

The Three Types of Gas Lawn Mowers

Rotary Lawn Mowers

Self-Propelled Lawn Mowers

Unlike the rotary lawn mowers, the self-propelled type is ideal for large yards as these can cover more ground. Its features include automatic clutches and adjustable speeds which enables it to push towards hills easier. 

Push Lawn Mowers

This type is a good choice for small yards with an outlet nearby. The advantage is that it is cheaper than its other counterparts. The only drawback is that it can be time and energy consuming.

Pros and Cons of a Gas Lawn Mower

Compared to their counterparts, gas mowers are generally quieter and less disruptive However, it is still noisier than the models with cordless power sources. It may not be a favorable choice for neighborhoods wherein houses are in close proximity. 

In terms of efficiency, it can cut through thick grass compared to the electric model. The drawback is that it needs maintenance at regular intervals.

It is also environmental-wise as it produces less carbon emissions. But it is still prone to gas and oil spills and may contribute more to pollution compared to their electric-powered counterparts. Another disadvantage is that gas-powered lawn mowers may have problems starting up during winters as they take a lot of time to warm up.

When it comes to sustainability and safety, when properly maintained, gas lawn mowers typically last ten years or more. However, it may be costly to repair a gas lawn mower past the ten-year mark. In the safety spectrum. Generally, gas lawn mowers are safe if the safety precautions are followed properly. Below you can find the safety measures to be done when using gas lawn mowers.

Factors to consider when buying a gas lawn mower

Have you already decided which type of lawn mower to buy? This list of factors will help you finalize which one is right for you. The factors you need to consider are: Yard size, environment and noise tolerance, Ground Slope, and Machine Capabilities and Features.

1. Yard Size, Environment, and Noise Tolerance

The yard size, the foliage to be cut, and your noise tolerance will help you decide whether you opt for gas mowers, electric mowers or push mowers.

If you have a spacious yard, gas lawn mowers are definitely what you need. If you have a large backyard, investing in gas mowers would be great as it can efficiently cut grass and effectively handle overgrown foliage. However, for limited and small spaces, it is advisable to use a push mower as it has minimal power source requirement and less noise production. 

If you are into less noise, you may also opt to buy the electric-powered mowers. The downside is that it has smaller blades compared to the gas lawn mowers, hence, it is not efficient in cutting thick weeds and tall grasses. 

2. Ground Slope

The way your yard is situated (with slope or flat) will give you an inkling on what lawn mower to purchase.

If your area has a high slope and uneven terrain, you may think twice before buying a gas mower. Gas mowers are heavy and may not be a good choice in sloped areas as it cannot evenly cut grass. Same with gas mowers, push reel models are also not the best choice for uneven and sloped ones. The four-stroke engine has more power and is more efficient, as two-stroke blades may perform poorly on slopes due to smaller blades. A better choice for uneven surfaces are electric-powered models. However, the downside is that it may emit some noise. Electric-powered models are also fit for flat and even areas.

3. Machine Capabilities and Features

With the machine’s right features and capabilities, yard maintenance will be a hassle-free and stress-free experience. Some of the features that you should look for in a lawn mower are: self-propulsion, mulching, blade width and position, and noise level.

With a mower’s self-propulsion technology, it will be capable of turning the wheels, hence, you won’t be unnecessarily strained from pushing. Another feature mentioned is mulching. If the machine is capable of mulching, it can bag your cuttings and dispose of them on the side. When it comes to blades, the bigger the better. With a bigger blade, for instance, a 22-inch one, you would need less time pushing the lawnmower. Take note, the size is not only what you should consider in a blade. It would be better if the blade height is also adjustable using levers.

In terms of noise, the larger and noisier does not mean the better.  Larger engines tend to be louder so if you have low noise tolerance or if you live in a neighborhood where noise is an issue, larger engines are a deal breaker. You may opt for a quieter model with a smaller engine.

Reminders and Safety Measures When Using the Lawn Mower

All machines may pose a threat to safety when not used and handled properly. In order to avoid these, here are basic protocols you must observe when handling your lawn mower.

  1. Refer to the owner’s manual especially if it is a newly-owned lawn mower.
  2. Get rid of anything that may jam the lawn mower or may cause damage to its parts.
  3. Protect your eyes. Wear eye protection devices.
  4. Make sure that children are at a safe distance from the machine.
  5. Be sure to check fuel levels before starting up the machine.

  8. Do not store a lawnmower with an empty tank.
  9. Do not store the lawn mower outside to prevent theft.

  11. If lawnmower lose power when moving, do the following: Check the grass height as it could be overwhelming for the machine, and sharpen or replace the blades.
  12. Lastly, if the mower is smoking, do not panic. Check if the oil chamber in the engine is overloaded or if there is oil leakage in the exhaust muffler. Consider a professional tune-up once mower emits a light-colored smoke and regular stalling.
