Help prevent long term damage to your lawn by using our spike grass aerator to break up compaction and dethatch your lawn. Spike aeration loosens soil and thatch to let air, water, and fertilizer down to the roots. The Yard Butler lawn aerator tool is heavy-duty, rust-resistant and was built to last. Our 36-inch yard aerator features a foot bar for extra leverage so you can tend to your lawn easily, without back strain.
