What Is a Lawn Aerator?

To maintain a uniformly green beautiful lawn, you should regularly apply basic lawn care practices such as mowing, fertilizing, watering, and aeration. It’s notable that aeration is by far the most important element of all. Aeration is the process of perforating the soil with small holes to let the air, water, and fertilizers penetrate deep inside and reach the plants' roots. This means the efficiency of fertilizing and watering greatly depends on aeration. Regularly and duly aerated lawns stand out for the vigorous and dense grass. Also, they are less susceptible to diseases and thatch build-up.

A lawn aerator is a special gardening tool used to aerate the green to quickly bring it back to life. You can choose between electric dethatchers, manual tools, and tow aerators, which are usually attached to a riding tractor or mower, depending on your needs. Machines or powered aerators are best suited for large-sized lawns. If you own a smaller plot of lawn, you may consider buying manual models which work great for average- and small-sized residential greens. All lawn aerators fall into two main types: plug and spike aerators. Plug or core tools feature hollow tines that pull out soil plugs and leave them on the surface. Spike tools employ sharp and solid spikes to make holes in the soil.

To maintain proper lawn care, you may want to complete your arsenal of gardening tools with a lawn mower and a fertilizer spreader.

GreenWorks 27022

The Best Remedy for a Healthy Lawn

If a dense layer of dead roots, stems, and grass clippings is killing your lawn, you definitely need an efficient remedy to restore your green’s health. This is where a corded dethatcher from Greenworks will come in handy. By removing the thatch from the surface, it allows the flow of water and nutrients to penetrate into the lawn. This, in turn, helps promote healthy grass growth, saturate the soil with oxygen, and decrease water run-offs.

The GreenWorks 27002 is a perfect solution for those of you who have been looking for an aerator that requires neither maintenance nor special skills. It has a single button that activates the tool. All you need to do is press it and then push the tool before you. Powered by a 10-amp electric motor, the GreenWorks 27002 is able to remove up to 14-inch path of grass in a single pass, which is sufficient to finish the job relatively fast. Depending on the needs of your lawn, you can adjust the depth of cut in one of three positions up to 0.4 inches. 

One of the practical features of the GreenWorks 27002 is that it comes with a kit of spare parts (18 tines), which eliminates spending in the near future. 

The GreenWorks 27002 is not only functional but also very convenient to use. It has a height-adjustable ergonomic handle with a padded grip and two sturdy rubber wheels that spin perfectly on all soil types. The start button is located on the handle so that you can press/depress it instantly. The cord lock keeps the extension cord securely in place allowing you to move the tool freely without tangling.

Agri-Fab 45-0365

An Affordable and Efficient Helper

Are you looking for an inexpensive, eco-friendly, and efficient way of improving the look and health of your lawn? Then your choice is the Agri-Fab Push Spike Aerator! This is a walk-behind model that requires neither gas nor electricity and is very easy to handle. It doesn't emit any harmful fumes and its operation is fully based on a user's manual force. Press it down and off you go. As simple as that.

Despite being quite cheap, the Agri-Fab Push Spike Aerator is built to last. It features a durable and well-thought-out construction that can easily withstand heavy use. Due to the 16” aeration width, it can also be used for aerating from small to mid-sized lawns. Based on star-shaped wheels with 5” to 7” spikes, the Agri-Fab Push Spike Aerator can easily slice into the soil up to 2.5”. By penetrating the soil so deeply, the tool allows the air and light reach the grassroots to improve the water and fertilizer intake by the soil. The aerator's performance can further be improved by adding extra load to a steel weight tray that comes with the tool. This will make spikes land deeper into the ground. 

Some users say that navigating this push aerator may quite a daunting task if the soil is dry and rough. Therefore it's recommended that you use it on the wet and soft soil.

Yard Butler ID-6C

When Simplicity is a Benefit

When something is simple, it is not necessarily low quality. In a case of the Yard Butler coring aerator, simplicity stands for ease of use.

Like other lawn aerators, the Yard Butler is designed to reduce soil compaction and improve water and fertilizers intake; however, as opposed to the majority of electric units that usually require some skill, the Yard Butler allows you to do it quickly and effortlessly.

Made of the first-grade stainless steel, the Yard Butler is reliable, solid, and durable. The operating principle of the tool slightly reminds that of a shovel, but it is far easier - all you need is to put your foot on the tool and the hollow tines will slide into the soil. Once they penetrate into the ground, they extract two plugs of thatch and soil leaving two 3.5-inch holes for the air, water, and nutrients. The Yard Butler doesn't have a collection bag, which means you will need to either collect the removed plugs of soil by hands or leave them on the ground to dissolve. By doing the latter, you will let your lawn get saturated with many useful microorganisms.

The obvious advantage of the Yard Butler over the peers is that it can penetrate very deeply into the ground. The more force you apply, the deeper the tines will dig into the soil. Though this process might seem quite tiresome, the results will exceed all your expectations. Your lawn will look beautiful, healthy and thick.
