Abstract
An aerator with active turf calibration of a ground sensor that provides signals to a controller relating to changes in slope of a ground surface. The controller adjusts the position of a coring head based on signals from the ground sensor. The controller determines an offset from a neutral position of the ground sensor based on signals from the ground sensor on a flat surface during aeration compared to the neutral position of the ground sensor on a flat surface from static calibration.
