The most basic type of aeration tools are hand-operated plunging tools. Common hand aerator tools include the spike hand aerator and core-pull hand aerator. Both types generally consist of a waist-high, T-shaped handle connected to a base plate. A line of spikes protrudes from the bottom of a spike aerator and a set of hollow cylinders protrudes from the bottom of a core-pull aerator. To use hand aerators, landscapers simply plunge the spikes or core-pulling cylinders of the tool into the lawn's surface.
The manual push aerator consists of a barrel lined with aeration spikes or core-pull cylinders attached to a T-shaped handle. A landscaper grips the handle and pushes the aerator's barrel from behind. As the barrel rolls across the lawn, its spikes or core-pull cylinders puncture and aerate the lawn's surface. Aerating a large area with a push aerators requires substantially less time than aerating a similar area with a hand aerator.
Walk-behind power aerators generally resemble manual push aerators, however, power aerators benefit from the addition of a gas or electric motor. Like manual push aerators, power aerators use either spikes or core-pull cylinders to puncture a lawn's surface. The power aerator's motor drives the motion of the aerator's wheels and barrel, reducing the amount of effort required to push the equipment across large lawns.
Like snow chains, tire-mount aeration tools are essentially a set of tire-mounted spikes. However, tire-mount aeration tools are specially designed to fit onto the tires of push or ride-atop lawn mowers. Tire-mount aeration tools allow landscapers to accomplish aeration during regular mowing. Tire-mount aeration devices typically use spikes to puncture the lawn's surface.
