Transform your Grandstand Multi-Force into an aerator with the 38-inch wide Multi-Force Hooker Aerator. You'll finish jobs faster than ever, as the aerator punctures up to six holes per square foot. Holes are approximately 1/2 in. wide by 1-1/4 in. long and up to 3 in. deep. Tines pierce deep into the soil, hooking and lifting loose plugs of dirt that disperse quickly, spreading nutrients over the surface. No unsightly hard plugs accumulate on the lawn. The lifting action of the tines prevents soil compaction that is common with hollow tine aerators and allows good filtration of air and water into the lawn.
