For larger property aeration, the tow behind AET48 is the ultimate in productivity and flexibility. The standard 48” modular unit easily configures down to 24” and features interchangeable parts. Each 24” unit has four tine stars with six tines each that core up to 3” deep. The unit can be configured up to 72” wide with the optional AET expansion kit (Part No. 361273). Optional water weight jugs eliminate bulky steel weights, and are positioned directly over the tines for better aeration depth.
