An apparatus for retaining soil aerating tines during soil aerating operations comprising a tine holding assembly having a plurality of holes therein, wherein each hole is adapted to hold a soil aerating tine therein, wherein the holes are arranged in a plurality of rows of holes, wherein a plurality of spaces separate adjacent rows of holes, wherein the holes of at least one row of holes are positioned between the holes of at least one other row of holes. The apparatus can have at least one space that is at least twice as wide as at least one other space. The apparatus can further comprise a plurality of tine holding members, wherein each tine holding member comprises at least one row of holes of the plurality of rows of holes. Tines can be inserted into the holes to form a zigzag pattern.

An aerator implements a drive system with an outboard transmission(s) in which the transmission(s) is arranged outwardly of a frame rail(s) of the aerator's chassis to deliver power to both a drive wheel(s) and a driven set of tines of a tine assembly. The tine assembly may include at least one non-driven or freewheeling set of tines between outer sets of driven tines. An adjustable depth control system allows for selecting a tine depth that can achieved through a single button push that lowers the tine assembly to the selected depth.

A ground treatment apparatus for loosening the ground, in particular in the case of ground with grass growth, comprising a support device and a holding device that is movably held thereon, on which a plurality of injection elements are held, a lifting device, by way of which the injection elements are insertable into the ground and are extractable therefrom, and a fluid provisioning device that comprises at least one reservoir for fluid, which can be supplied with fluid for intermediate storage and which is directly or indirectly in fluidic connection with a plurality of injection elements. The support device and/or the holding device comprise at least one frame made of interconnected structural elements, wherein the at least one reservoir forms a structural element of the frame.

The invention relates to a lawn maintenance machine comprising a container (10) and a movable wall (40), the movable wall (40) dividing the container (10) to a first storage (20) having a first length in a longitudinal direction, and a second storage (30) having a second length in the longitudinal direction, wherein the second storage (30) is placed rearward from the first storage (20), the lawn maintenance machine further comprising an actuator arrangement configured to move the movable wall (40) forward and backward in the longitudinal direction in order to increase and decrease, respectively, the volume of the second storage (30). The invention further relates to a method for taking care of a lawn or a turf. This invention further relates to a lawn maintenance method and a lawn maintenance system.

A riding hydraulically driven aerator is disclosed herein. The aerator includes a frame, an engine, one or more hydraulic pumps, one or more drive wheels, one or more tine assemblies, and one or more hydraulic motors. The hydraulic motors are coupled to the drive wheels and to the tine assemblies. The hydraulic pumps provide power to the hydraulic motors and are coupled to the engine with a toothed timing belt.

A core collector for collecting aeration cores lifted from a ground surface by a ground aerator machine includes a skid plate having a bottom surface opposite the ground surface and a top surface opposite the bottom surface. The skid plate has a plurality of openings in the skid plate extending between the top surface and the bottom surface at a proximal end of the skid plate. The plurality of openings are spaced apart from each other based on a spacing of extraction tines of the ground aerator machine. The core collector has at least one core clearing member. Aeration cores are deposited directly onto the top surface of the skid plate. The at least one core clearing member is configured to clear the aeration cores from the proximal end of the skid plate toward the distal end of the skid plate.

A cylindrical turf treatment rotor adapted to be driven in rotation about a horizontal axis, and provided with wear-resistant teeth extending along one or more helical tracks on the rotor, the teeth being individually attached to the rotor so as to be capable of individual removal for replacement or refurbishing or for reconfiguring the rotor.

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.
