  • Aerator with variable delay of coring head
    Patent number: 10206321
    Abstract: An aerator with variable delay of the coring head includes a lift/lower control on an aerator control panel that raises and lowers a coring head and starts or discontinues rotation of a coring head crankshaft that reciprocates a plurality of coring tines. A delay timer provides a variable time period between starting to raise or lower the coring head and the rotation of the crankshaft. A switch is provided on the control panel to preset the time period.
    Type: Grant

  • Aerator with active turf calibration of ground sensor
    Patent number: 9510497
    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.
