Billy Goat AE401HThis unit completely eliminates the conventional and cumbersome centre wheel and centre drum designs found on other units, which are prone to wear, vibration and damage. Billy Goat's outboard drive wheels also eliminate centre wheel slip and abuse from ramp loading with the tines engaged. Additionally, the AE401 also eliminates bulky steel weights, in favour of a simple to use water weight positioned directly over the tines for better aeration depth. The unit features the industry's softest tine engagement and exclusive Lift N Lock disengagement for best in class comfort and productivity. After use and during transport, tilt up serviceability, removable tine stars, and Fold-n-Go handles, and easy adjust drive chains make service and transport convenient and simple.
