Abstract:
A soil penetrating apparatus having an automatic tool (e.g., aerator tine) depth control system and method. The system includes an actuator that sets and controls tine depth, a sensor that monitors tine depth, and a controller that controls the actuator in response to the sensor. In some embodiments, the actuator is a hydraulic actuator, wherein once tine depth is set, flow to the actuator is bypassed. A relief may be provided to allow the tines to lift to a shallower depth temporarily when soil hardness exceeds a threshold. The system may then automatically return the tines to the pre-selected depth once soil conditions permit.

Claim (Index 5):
A turf aerator comprising:\n a chassis; a coring head assembly operatively attached to the chassis and movable between an elevated position and any one of a plurality of aerating positions; a control input adapted to select a desired soil penetration depth corresponding to one of the plurality of aerating positions of the coring head assembly; a linear hydraulic actuator adapted to move the coring head assembly between the elevated position and any one of the plurality of aerating positions; a controller adapted to command the actuator to a position corresponding to the desired soil penetration depth; a sensor adapted to provide a feedback signal to the controller corresponding to the position of the coring head assembly; and a valve adapted to:\n deliver hydraulic flow to the hydraulic actuator while the coring head assembly moves from the elevated position to the desired soil penetration depth; and \n bypass, with the hydraulic flow, the hydraulic actuator while the coring head assembly is at the desired soil penetration depth.
