Top 7 Best Lawn Aerator Reviews in 2021

The best lawn aerator can improve the health of your lawn by helping the grass quickly recover after being trodden upon. Aerating also improves the lawn’s ability to absorb water so that grass can grow deeper and stronger roots. Here are 7 of the best-rated lawn aerator machines we like:

Very easy to operate, the Agri-Fab 45-0365 aerator is more-or-less fully assembled so you do not have to spend time putting it together. It is also lightweight and measures no more than 15 lb.

For owners of a small to medium-sized lawn, this could be an excellent, cheap lawn aerator. It’s compact, lightweight, and it works well on a small expanse of land. After using this rolling lawn aerator, you’ll undoubtedly see a visible difference in your lawn.

The bars and tines on this aerator are made with sturdy steel. However, the rolling parts on both sides are plastic. While this reduces the aerator’s overall weight and makes it easier to maneuver, it makes me think the product might not be as durable as I’d like.

Types of Lawn Aerators

Depending on the type and size of lawn you have as well as the climate you live in, lawns need to be aerated at least twice a year: in the spring and fall. Here are the types of aerators to choose from:

Tow-Behind Aerators

Tow or walk-behind aerators are designed to perforate the lawn with small holes as you walk behind them thereby loosening the soil. This allows water, air, and other nutrients to penetrate deeply and reach the grassroots. The deeper the grassroots reach, the stronger and healthier the lawn.

Spike Aerators

These aerators slit an opening in the soil and typically have the appearance of a series of spurs located on a rolling axle. The axle is suspended from and rotates beneath the frame of the aerator and some units also have room for additional weight. The weight helps deeper penetration of spikes or tines of the aerator head into the soil.

Plug Aerators

Plug aerators have the appearance of star-shaped or funnel-type knives rotating on the axle which removes and drops out plugs of grass and soil. These plugs should be left as is on the lawn as they contain nitrogen and other vital nutrients your lawn needs.

Factors to Consider When Selecting the Best Lawn Aerator

Here are the factors to consider when selecting a lawn aerator:

Size of the Lawn/Yard

You need an appropriately sized aerator that can easily cover a small to mid-sized lawn. You certainly don’t want too small an aerator that would take several hours of hard work. Select an aerator with an appropriate width so it can cover a wider area in a short amount of time. You also can go in for aerators which can be hitched to an ATV or a tractor in case you want to cover a very large yard/lawn/farm.

Height and Weight of the Operator

Some aerators need the operator to stand on them in order to apply pressure which can help the aerator tines or spikes penetrate deeper into the soil. So, do consider your weight. A lighter person would require a lot more time to cover a larger area. Similarly, select the right size of handle for the aerator so that you don’t have to bend too much or strain your back.

Type of Soil

Very hard, compacted or clay-type soil can need some moisture to loosen up. Such soils need to be wet thoroughly before using the aerator tool. In such cases, you may want to choose an aerator that works with cinder block weights. They have a special base upon which you can place the weight so that the spikes can easily penetrate deeper into the hard/compacted soil without causing a strain on the operator.

Frequently Asked Questions (FAQs)

Q: Which Is Better Between Hand-Pushed and Tractor-Powered Lawn Aerator?

Hence, for a small-sized lawn, it is best to opt for a hand-pushed lawn aerator because they use muscle power to operate. Besides, hand-pushed lawn aerators use muscle power to function, and they are inexpensive. On the other hand, tractor-powered lawn tractors are ideal for big yards to clean the soil and fertilize it.
