Aerating a lawn creates better drainage, compaction relief, and allows nutrients to sink to the bottom resulting in a lush, green, healthy lawn. Become the envy of all your neighbors with the Billy Goat PL1800 Series PLUGR Mechanical Aerator that operates with 4 easy to remove tines connected to a reciprocating crankshaft assembly to punch core depths into the soil at 2.75 inches. Maneuver around your lawn easily with the 12 inch tires that allow for easy turning and steering without lifting. Operation is a piece of cake with the Tine engagement lever and bail that can be stopped and started quickly for passing obstacles such as a sprinkler system. And, when you are finished aerating, simply fold the hand down for convenient transportation and compact storage.
