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 spike aerator! Just position, step and pull up firmly. The four 3" spikes loosen soil and thatch to let air, water and fertilizer penetrate deep into roots. The long handle design allows you to aerate while standing tall, saving you time and minimizing back strain. 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.
