Tiller vs. Aerator

Gardens and lawns require excessive care and routine maintenance. Whether you intend to grow something or just want a neat, nice looking lawn, in both cases, you require the right equipment and skills for it. These two are co-related and rely on each other. While you might have the right skills, but, without the right equipment, it will be a challenging task. 

Talking of the right equipment, tiller vs. aerator is the first question that comes into any individual’s mind when they are looking for ways to manage their lawn, backyards, or gardens and ensure the soil is in ideal conditions for growing and planting. Both tiller and aerator are equipment meant to prepare your soil for growing purposes.

Although they might have the same primary purpose, they have their differences as well. If you have the same question in mind, “Tiller vs. Aerator,” you’re in the right place and I’ve got you covered. Without any further ado, let’s dive into how these two differ, and how you can use them.

Tiller: What Is It, And When To Use One?

A tiller is essentially garden equipment used to prepare the soil for planting, by turning over soil. Irrespective of the size of the property, a tiller can be used to effectively turn the soil and allow it to grow new seeds, at a much faster rate. In addition, tilling also provides the soil with new nutrients required for the growth of new seeds.

Types of Tillers

Tillers can usually be classified into three categories based on their mechanism and how they operate. These are;

  • Front-tine Tillers
  • Rear-tine Tillers
  • Vertical-tine Tillers

Front-tine Tillers

As the name suggests, a Front-tine tiller has two blades, located right under the engine essentially,  at the front-end of the tiller’s wheels. Front-tine tillers are mobile and can be maneuvered with ease. 

These are better suited for gardens with narrow rows –thus effectively mixing, and composting the soil. For small gardens, front-line tillers are the go-to.

Rear-tine Tillers

Rear-tine tillers have blades located at the rear-end of the tiller, ideally, behind the wheels. These are equipped with much larger wheels compared to the front-tine tillers and are in fact, heavy-duty tillers. There further have different types of operating mechanisms. 

Rear-tine tillers are available with forward rotating and counter-rotating mechanisms, and can also have both equipped in a single tiller. These are essentially much more powerful compared to other tillers and are used for preparing the soil for a new garden. For larger gardens, rear-tine tillers are the go-to.

Vertical-tine Tillers

Vertical-tine tillers are a newer addition to the family of tillers. Unlike both front and rear-tine tillers, these are equipped with blades that cut forward into the soil. Vertical-tine tillers are relatively easier to use and maneuver as well. 

For breaking soil on new gardens, vertical-tine tillers are the go-to.

When To Use A Tiller?

Tilling is the process of preparing the soil for plantation by turning over the soil. Not only will you be able to prepare your soil for planting using a tiller, but you will also be able to add nutrients into the soil to ensure your plants grow to their full extent. This is also referred to as plowing.

Irrespective of whether you use a front-tine, rear-tine, or vertical-tine tiller, all of these are used to break down the soil. They only vary when it comes to the size of the garden. If you’re considering getting a garden tiller check here the best.

You should use a tiller prior to planting new seeds in the soil, this will allow vital nutrients to reach your plants and will ensure the soil is in optimum conditions for plant growth. However, keep in mind to use a tiller only in the fall or spring season.

Another factor that needs to be considered before using a tiller is to ensure the soil is not wet. One way to check your soil prior to using a tiller is to take some soil in your hand and squeeze it tightly, if you do not notice any moisture, you’re good to go. 

Aerator: What Is It, And When To Use One?

As you can tell from the name, aerator, it is essentially used to provide the soil with oxygen and allow it to stay aerated. Plants require both water, and air for their ideal growth, and an aerator is one way to provide them with extra oxygen, using the soil.

An aerator is garden equipment used to create tiny holes in the soil/ground. This allows the plants to receive more oxygen and in return, it boosts their growth and allows them to stay greener. This also allows your plants to stay healthy by enabling them to grow deeper roots.

Types of Aerators

Aerators can usually be classified into two categories based on their mechanism and how they operate. These are;

  • Spike Aerator
  • Plug Aerator

Spike Aerators

As you can tell from the name, spike aerators feature sharp spikes that are used to make holes in the soil and loosen it effectively. Spike aerators do not remove any soil in the process of aerating it. Since no soil is removed, this allows temporary soil decompaction and would require periodic usages. 

Plug Aerators

Plug aerators feature hollow tines that remove a small portion of the soil and grass. This results in holes in the soil by removing a fraction of soil and thus allow your soil to stay aerated for much longer periods. It can also be referred to as long-term soil decompaction primarily because of the holes. Unlike spike aerators, plug aerators do not require a lot of effort and are often the go-to for many people. 

When To Use An Aerator?

After you’ve used a tiller and begin to see your seedlings grow, you should immediately aerate your soil. This allows the soil to get more oxygen since water and air are the primary requirements for the healthy growth of plants. Similar to tilling, aerating your soil in the fall and spring would lead to better results. 

You should aerate the soil after your seeds grow, and notice that the grass is dull and unhealthy. However, if it is green and healthy, there is no need to aerate the soil. 

Tiller vs. Aerator: Which One Should You Use?

The primary purpose of using a tiller and an aerator is to promote the healthy growth of your plants by preparing the soil. 

A tiller is used to break down the soil and add nutrients to the soil, such as a fertilizer to ensure your plants grow to their full extent. A tiller is also used as a means to reseed grass in your yard. This allows the soil to be remixed and thus improves the drainage as well. Keep in mind, you should use a tiller prior to using an aerator. Tilling is crucial before plant growth and therefore needs to be done every year. 

Whereas, an aerator is used to create holes in the ground to further boost the growth of your plants by providing the soil with more oxygen. Keep in mind, you should only use an aerator after you’ve used a tiller to cultivate your soil. Aerating your soil is only necessary if you find your grass pale and unhealthy. 

Another factor to consider is that you should only use these garden equipment, tiller, and aerator, only in the fall and spring season. 


Tilling and aerator are both means of preparing the soil for plantation. Tilling is essentially the process of breaking down the soil by turning it over. This allows your soil to be in the optimum state for plantation. Besides, tilling also allows you to add vital nutrients to your soil to facilitate plant growth.

The aerator, on the other hand, is a process of creating holes in the soil to allow oxygen to reach the soil and result in your plants having deeper roots. The aerator is only meant to be used after using a tiller, once you see your seedlings grow. However, it isn’t compulsory and only has to be used if your newly grown seedlings and grass are unhealthy.
