The swing arm being rotatably supported by the frame and configured to rotate the plurality of tines between an operating position and a retracted position. Actuation of the input (i) actuates the swing arm to transition the plurality of tines from the retracted position to the operating position and (ii) activates the tine shaft to move the plurality of tines.

A detection system for use with a powered ground maintenance vehicle, the detection system adapted to detect and avoid contact of a ground maintenance implement carried by the vehicle with an object associated with the ground surface. In some embodiments, the detection system may automatically disengage the implement from the ground surface before the implement contacts the object and, optionally, automatically re-engage the implement with the ground surface after the implement has passed the object.

A turf aerator includes a tine assembly and an input mechanism. The tine assembly includes multiple tines, a retractor plate for positioning the plurality of tines, and a linkage for selectively moving the retractor plate and the plurality of tines between an operating position and a retracted position. The input mechanism coupled to the linkage, the input mechanism operable to activate the linkage to move the retractor plate and the plurality of tines between the operating position and the retracted position.

A turf aerator includes a retracting tine assembly and an input mechanism. The tine assembly includes a plurality of tines, a pair of swing arms, and a linkage for selectively moving the pair of swing arms and the plurality of tines from the operating position to the retracted position. The pair of swing arms support the plurality of tines and are configured to rotate the plurality of tines between an operating position to a retracted position. The input is coupled to the linkage and the input is operable to active the linkage to move the pair of swing arms and the plurality of tines from the operating position to the retracted position.

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. In order to provide such a ground treatment apparatus that has a more compact design, it is proposed, in accordance with the invention, that 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.

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.

A handheld gardening tool includes a power source, a spike projection device adapted to roughen soil for the application of grass seeds or to ease pulling weeds, and a support arm connecting the power source to the spike projection device. The spike projection device comprises a housing supporting a plurality of spikes mounted within the housing for controlled extension from and retraction within the housing for engagement with soil.

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.

A turf aerator is disclosed which is configured with components that allow a user to set a desired turf aeration depth and then automatically adjust hydraulic pressure to produce a proper level of downward pressure into the ground in order to maintain consistent depth penetration with the tines. The turf aerator implements a depth control lever that is operatively connected to a switch that increases or decreases tine depth up or down. Since the desired tine depth is set and the hydraulic pressure is capable of puncturing the ground accordingly, portions of the ground that are relatively harder or softer are still properly penetrated due to the set level of depth. The turf aerator is also configured with a tine housing which shields drive chains from dirt and debris from the aerating, thereby increasing the life of the drive chains.
