摘要： 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.

摘要： 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). 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). Thus, the outer tine assemblies (104) are located intermediate the inner tine assemblies (100a, 100b) and the outer ends of the two independently rotatable shafts (102).

摘要： An integrated aeration spreader for use with an aerator includes a mounting plate, a mounting block rigidly coupled to the mounting plate, a support arm rotatably coupled to the mounting plate, a support block rigidly coupled to the support arm, wherein the mounting block is located a first distance from the support block, a shaft rotatably coupled to the support block, wherein the shaft extends through the mounting block, a first nut threaded on the shaft, wherein the first nut is located a second distance from the support block and the second distance is less than the first distance, a first spring having a first end engaged with the first nut and a second end engaged with the mounting block, a second nut threaded on the shaft, wherein the second nut is located a third distance from the support block and the third distance is greater than the first distance, and a second spring having a first end engaged with the second nut and a second end engaged with the mounting block. The integrated aeration spreader combines a spike-type aeration and sand spreader that fills the aeration holes in a single pass of a vehicle, after having a top dresser vehicle lay sand down over the ground and grass-covered surface to be aerated.

摘要： A ground treatment apparatus comprises a support device, injection elements, a fluid providing device that is fluidically connected to the injection elements, a drive device by which the injection elements are on the one hand lowerable and raisable in relation to the support device and on the other movable along a working direction of the ground treatment apparatus. The injection elements are insertable into the ground by being lowered in order to inject fluid into the ground in a treatment region, wherein the injection elements remain stationary during engagement in the ground in the treatment region, with relative movement in relation to the support device that is moved in the working direction, wherein the injection elements are raisable after the injection of fluid and are movable in the working direction in relation to the support device, wherein, on being lowered again, the injection elements are insertable into the ground in a further treatment region that is downstream of the first-mentioned treatment region, as seen in the working direction.

摘要： A walk-behind aerator with hydrostatic drives is disclosed herein. The aerator includes a frame, an engine, a first and a second hydrostatic drive, a first and a second drive wheel, a first and a second idler wheel, and a first and a second tine assembly. The first hydrostatic drive may power the first drive wheel and the first tine assembly and the second hydrostatic drive may power the second drive wheel and the second tine assembly. In some embodiments, the aerator may further include a first and a second drive chain, a first and a second tine shaft, one or more control levers, and one or more covers. The one or more control levers may be linked to the hydrostatic drives by one or more linkages through the frame. The covers may be located between the tine assemblies and the drive chains and linkages.

摘要： An agricultural tillage implement has a vertical tillage section and an aerating section behind the vertical tillage section, each extending substantially perpendicular to the pull direction of the implement. Individual vertical tillage elements, such as disc blades, can be indexed with individual rotary tine assemblies of the aerator section so that discrete holes formed by the aerator section are positioned between substantially continuous slits formed by the vertical tillage section. Rolling baskets can be provided behind the aerator section for further soil conditioning.
