A core aerator will remove small plugs of soil and thatch and drop them back on the lawn. This opens the way for air, water, and fertilizer to reach the root zone of the turf.

The extracted plugs will lay on the surface where they decompose and will be mulched up in the following week's mowing.


Aeravation is a process of fracturing the soil with oscillating solid tines. This results in instant aerification and the breakup of compacted soil preparing the perfect environment for seed germination with ideal seed to soil contact. When paired with overseeding, aeravation essentially plants grass. There are also no messy plugs left on the surface.

What is the best method and machine for lawn aeration?

There are different types of aeration machines. One of the more common types is known as a drum style. The drum style as a rail with several sets of coring attachments set in a row and spaced out around the drum. As the drum is moved over the surface of the ground the coring attachments go down into the ground removing the core. The core is then pushed out of the coring attachment on the machine by repeating the action. The spacing of the cores is related to the arrangement on the machine and slowing or speeding up the ground travel speed will never affect the spacing between core holes.

Another type of aeration machine is a camshaft style machine. In this style, the coring attachments are each attached to an offset cam which is attached to a camshaft driven by an engine, belt, or a PTO shaft. There is often a lever that once released allows the coring attachments to be release forward and penetrate the top of the thatch layer into the soil. The difference between the camshaft style and the drum style is that the spacing between the cores on the camshaft style is directly related to the ground travel speed. Since the engine/PTO drives the camshaft at engine RPM. The machine that the unit is attached to determines the ground travel speed via the operator controls. This means the slower the ground speed the closer the cores are together as well as reaching their maximum allowed depth. The faster the ground speed the farther the cores are apart as well as being more shallow as the attachments will be swung back due to momentum.

Here at Spike's Lawn Care, we have the ability to do both styles. Although the process is a bit slower I prefer to use the camshaft style machine to get the highest optimum results passing the added value on to my customers.

Why does your lawn need Aeration?

Aeration is a simple term that means “to treat with air.” The process of aerating a lawn involves the use of equipment to perforate holes in the soil, bringing it up to be treated with not only air, but water, fertilizer and sunlight. This is a basic explanation, but there is a lot more that goes into soil aeration.

Aeration provides the means to loosen the soil to correct the compaction problem. Also, over time, your lawn will naturally build up thatch. Thatch is simply an intermingled layer consisting of dead stems, roots, and leaves. The problem is that this layer builds between actively growing grass and the soil underneath it; when the layer becomes too thick, it prevents water, nutrients and flow of air from reaching the soil layer. Aeration assists in reducing this problem of thatch build up.

For healthy grass to keep growing on your lawn aeration needs to be part of your lawn maintenance.

There are several benefits for core aeration. The most obvious one is that it helps rejuvenate your lawn and keeps it looking healthy. Other benefits include:

  • Improved air exchange between the soil and atmosphere
  • Enhanced soil water uptake
  • Improved fertilizer uptake and use
  • Reduced water runoff and puddling
  • Improved turfgrass rooting

  • Reduced soil compaction
  • Enhanced heat and drought stress tolerance
  • Improved resiliency and cushioning
  • Enhanced thatch breakdown

When should my lawn be aerated?

Optimally fall is the best time to core aerate, this also coincides with the best time to do overseeding. Simply for the reasons of the cooler fall temperatures as well as not interfering with the pre-emergent crabgrass control in the spring. Cool season turf grass such as the most common cool-season grasses in Minnesota are Kentucky bluegrass, Fine fescue, and Perennial ryegrass.

Aerating is just one of many techniques used to renovate and develop your lawn. Most of the methods to lawn restoration include aeration, but the best route is to combine strategies for maximum results. Amending topsoil with organic fertilizers, core aeration, reseeding post-aeration and top dressing are some common ways to rejuvenate a lawn.

How long does this process take?

The time it takes for soil aeration depends on the size and condition of your lawn. For a realistic estimate, please call or email our technician at Spike's Lawn Care.

Spike's Ventrac AERA-vator Programs

The AERA-vator is designed to stir and loosen the soil beneath the sod without destroying the turf. The machine creates a core hole without bringing a core plug to the surface, leaving the turf ready for use immediately after treatment. Nine holes are created each foot (97 holes per square meter) and hole size is regulated by drive speed-- the slower the drive speed, the larger the hole. The AERA-vator works best in dry un-irrigated ground leaving a core hole while fracturing the sub soil.

Aera-vation Benefits
Aeravation, our specialized aeration service, provides an avenue for water, nutrients, and oxygen to get to the root zone. Aerating your lawn helps reduce thatch accumulation and alleviate compaction.

Overseeding Benefits
Add overseeding to help thicken thin and bare areas and to introduce new and improved grass varieties to your existing turf. If you are wanting a lush, green lawn that the neighbors will envy, core aeration and overseeding can provide lasting results.
