Step up to the unique features of Billy Goat’s 19" wide AE401H aerator and see for yourself why people are switching. Operators love the softest drive and tine engagement in the industry and the "Lift and Lock" feature that allows the tines to be raised by simply lifting up on the handle. The AE401H eliminates cumbersome filling of a conventional center drum found on other units on the market, which is prone to wear, vibration and damage. Instead of bulky steel weights, water weight is positioned directly over the tines for better aeration depth. Thick ‘O-ring’ style chain for long life, better lubrication and stands up to pressure washing.
