Imagine a lush, green expanse of grass, perfectly trimmed and inviting. Now imagine a noisy, smelly machine that makes short work of keeping it that way. That, my friends, is the magic of the lawn mower. But what exactly is a lawn mower, and how does it work? This article will delve into the world of lawn care, exploring the history, types, and working mechanisms of this ubiquitous machine. We’ll also touch upon how to choose the right mower for your needs and address some common concerns you might have about lawn mowing.
In a nutshell, a lawn mower is a motorized or manual machine designed to cut grass to a uniform height. It utilizes blades rotating at high speed to trim grass blades, giving your lawn a neat and tidy appearance.
A Brief History of Lawn Mowing: From Scythes to Self-Propelled
The act of trimming grass has been around for centuries. Early methods included using hand-held tools like scythes, sickles, and shears. While effective, these methods were labor-intensive and time-consuming.
The invention of the lawn mower revolutionized lawn care. The first known patent for a lawn mower was granted in 1830 to Edwin Budding, an English engineer.

Understanding the Mechanics: How a Lawn Mower Cuts Grass
The fundamental principle behind lawn mower operation is straightforward: a rotating blade cuts grass blades to a uniform height. However, the specifics vary depending on the type of mower.
Reel Mowers: Reel mowers use a rotating reel fitted with blades that cut grass like a pair of shears. As the reel spins, the blades glide over the grass, cleanly slicing each blade at the desired height.
Rotary Mowers: Rotary mowers utilize a rotating blade that spins within a protective deck. The blade’s high speed generates a centrifugal force that throws grass upwards, where it’s then cut by the blade. The cut grass is then discharged either into a collection bag or onto the lawn.
Choosing the Right Lawn Mower: Considerations and Factors
Selecting the ideal lawn mower involves considering your specific needs and preferences. Here are some important factors to keep in mind:
Lawn Size: The Bigger, the Better?
The size of your lawn is a key determinant in choosing a mower. For small lawns, a manual reel mower might suffice. Larger lawns often require a powered rotary or robot mower to ensure efficient and timely mowing.
Terrain and Grass Type: Navigating the Landscape
The terrain and type of grass on your lawn influence your mower selection. If you have a hilly or uneven lawn, a self-propelled or robot mower might be more suitable. Thick, dense grass might require a powerful rotary mower with a mulching function.
Budget: Finding Value and Quality
Lawn mowers are available at a wide range of price points. Your budget will influence the features and quality of the mower you choose. While inexpensive models might be tempting, investing in a high-quality mower can save you money in the long run due to its durability and longevity.

FAQ
1. What kind of insect sounds like a lawnmower?
The insect that sounds most like a lawnmower is the cicada. These large insects have a distinctive buzzing sound that can be quite loud. You may even mistake it for a lawnmower if you’re not paying close attention. Cicadas are common throughout the United States and are most active during the summer months.
2. How can I tell if it’s a cicada or a lawnmower?
There are several ways to tell if the buzzing sound you hear is from a cicada or a lawnmower. First, look for the source of the noise. If you see a large insect perched on a tree, it’s likely a cicada. Second, listen carefully to the sound. Cicadas have a very distinctive buzzing sound that is often described as a high-pitched whine. Lawn mowers, on the other hand, produce a lower-pitched humming sound.
3. Why do cicadas make that noise?
Cicadas are known for their loud buzzing sound, which is actually a mating call. Male cicadas use their tymbals, which are specialized organs located on their abdomens, to produce the sound. The sound is amplified by the cicada’s hollow body, making it audible from great distances. This loud buzzing is the male’s attempt to attract a mate.
4. Are cicadas harmful?
Cicadas are not harmful to humans. They do not sting or bite, and they do not carry diseases. In fact, cicadas are actually considered beneficial insects because they are a food source for birds, reptiles, and other animals. However, they can be a nuisance due to their loud buzzing sound.
5. When are cicadas most active?
Cicadas are most active during the summer months. This is when they emerge from the ground as adults and begin their mating cycle. The duration of their emergence varies depending on the species, but it can range from a few weeks to several months.
6. What should I do if there are a lot of cicadas in my yard?
If you find yourself with a large number of cicadas in your yard, there isn’t much you can do about it. Their life cycle is naturally cyclical, and their presence is a sign of a healthy ecosystem. Just try to enjoy their presence during their short time on the surface!
7. How long do cicadas live?
Cicadas live for a relatively short time above ground. However, their underground life cycle can be much longer, sometimes lasting 13 or 17 years. During their time above ground, they primarily focus on mating and laying eggs. This short, but loud, period is what makes cicadas so memorable.
