Your yard's high-traffic areas get compacted with thatch over time, depriving roots of water and air. Breathe new life into your lawn with this ergonomic core aerator! Just position, step and pull up firmly to remove two 1/2" dia. x 3-1/2"D plugs, which assists the flow of water, fertilizer and air deep into the roots. The long handle design allows you to aerate while standing tall, saving you time and minimizing back strain. Leave the cores on the lawn surface where they can break down and provide rich organic material back into your grass. Yearly use promotes vigorous root growth, reduces water runoff, strengthens tolerance to drought and heat stress, and helps avoid using excess grass supplements or fertilizers.
