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.

摘要： 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 on independently rotatable shafts (102) to which inner tine assemblies (100a, 100b) are connected. A tine cover (50) removably closes an opening (40) in the top plate (28) and in which weights (70) are removably received over the tine assemblies (100a, 100b, 104). Transport wheels (134) are moveable by pivoting a stop plate (140) to position an upper pivot axis (150a) of an abutment bar (150) ahead of or behind the stop axis (142) and lower pivot axis (150b). A stop (146) positioned on the stop plate (140) without the use of tools adjusts the depth of the tine assemblies (100a, 100b, 104).

摘要： In an aerator including a chassis mounted on wheels, a tine depth stop mechanism includes a base mounted on the chassis. A side wall is fixed to the base and has a plurality of apertures therein. A stop arm is movably mounted with respect to the side wall and has an abutment. The abutment has a periphery. A tine weldment is attached to the stop arm, and a tine wheel is rotatably mounted to the tine weldment. A pin passes through one of the apertures of the side wall and engages the periphery of the abutment of the stop arm. Upon a downward movement of the tine wheel, the stop arm moves with respect to the side wall until the pin abuts the periphery of the abutment, thus adjusting a maximum depth of the tine wheel below the chassis.
