Abstract: A ground aeration device is described herein. The ground aeration device includes an air supply connector for receiving pressurised air from a source, a first supporting element for supporting a drill element for insertion into the ground, and a hydraulic hammer means. The drill element includes a cavity operably connected to an aperture a pneumatic means operably connected to the air supply comprising an actuating means for controlling supply of pressurised air through the drill element. The pneumatic means is arranged on the first supporting element. The aeration device further comprises a second supporting element, slidably attached to the first supporting element. A hydraulic means is attached to the first and second supporting elements. The first supporting element being movable via the hydraulic means from an initial parked position to a first position relative to the second supporting element.

Abstract: Tines (120) of tine assemblies (100a, 100b, 104) are secured by a single bolt (126) extending diametrically through each tine (120) located in a cavity (112) of a tine plate (110), through the tine plate (110) and through an attachment ring (130). The attachment ring (130) of an outer tine assembly (104) is connected to a sleeve (116) rotatably mounted adjacent the outer ends on each of two independently rotatable shafts (102) to which inner tine assemblies (100a, 100b) are rotatably connected adjacent the inner ends of the two independently rotatable shafts (102). The attachment rings (130) of the inner tine assemblies (100a, 100b) are welded to the two independently rotatable shafts (102).

Abstract: A stand-on aerator includes a chassis, an operator platform extending from a rear portion of the chassis, an aerator assembly coupled to the chassis and having a plurality of reciprocating tines configured to extend from and retract into the aerator assembly, and an object detection sensor. At least a portion of the plurality of reciprocating tines are configured to retract in response to the object detection sensor detecting an object in a path of the aerator assembly.

Abstract: A self-propelled lawn care appliance for aerating and subsoiling the ground below a turf includes a chassis, an implement with piercing tools movable up and down for piercing the ground for subsoiling, and an optical lane recognition device comprising at least one camera and an image processing unit. In a first mode of operation of the lawn care appliance, the lane recognition device is designed to recognize a hole pattern of an area of the ground previously treated by the lawn care appliance and, based thereon, a boundary of a previously treated lane. In a second mode of operation of the lawn care appliance, the lane recognition device is designed to recognize a defined boundary of the deposited soil material of a ground area previously treated by the lawn care appliance and, based thereon, the boundary of a previously treated lane.

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.
