An aerator for a turf surface has a traction control, an OPC bail, and an aeration bail capable of single handed operation. A controller automatically lowers a tine head to begin aerating at a start location marked when the aeration bail is closed and lifts the tine head to end aeration at an end location marked when the aeration bail is released. The controller further causes the tines that enter the turf surface at the start location to penetrate to a desired hole depth. The controller also automatically adjusts ground speed to maintain a desired hole spacing during an aeration pass, but permits the operator to speed up during a turnaround between passes with a steerable front wheel freewheeling to mitigate wheel scrubbing. A handle assembly having a spring counterbalance is height adjustable and automatically engages a parking brake when placed in an upright non-operating position.

A towable element for a lawnmower, the towable element includes a carriage defining a work tool receiving area; an engagement feature coupled to the carriage, wherein the engagement feature removably interfaces with a complementary engagement feature of the lawnmower to selectively couple the towable element with the lawnmower; and a work tool removably disposed at the work tool receiving area, wherein the work tool acts on an underlying ground surface below the towable element.

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.

A perforator quick disconnect system for an aerator device includes a perforator and a retaining device. The perforator has a head with an exterior configured to be received within a mounting block of the aerator device and a female component that extends into the exterior of the head. The retaining device has a connector configured to connect to the mounting block and a male component disposed within the connector and moveable relative thereto from a first position to a second position. The female and male components together form a quick disconnect mechanism such that when the perforator and retaining device are received by the mounting block, the male component engages the female component when the male component is in the first position to connect the retaining device to the mounting block and disengages the female component when in the second position to disconnect the perforator from the mounting block.

A system and method for aerating turf including an eight-tine block for use in combination with an approximately -inch or less in diameter tine in a self-propelled mechanized turf aerator with a forward movement setting of 1.5-inch between downward movements of the tine block. The system includes a self-propelled mechanized turf aerator; a 24 tine block affixed to the self-propelled mechanized turf aerator, the 24 tine block including two rows of four holes in each row, each hole sized approximately -inch in diameter; and tines including a proximal end of about -inch in diameter for insertion into the 24 tine block holes, and a distal end about -inch or less in diameter for insertion into a turf site.

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 soil treatment apparatus for loosening soil includes a supporting device and a holding device movably held on the supporting device. A plurality of injection elements are held on the holding device. The injection elements are insertable into and withdrawable from soil via a lifting device. A fluid supply device is in fluid connection with the injection elements for providing fluid. The supporting device includes a first supporting device portion and a second supporting device portion. The soil treatment apparatus is configured to be caused to move in a processing direction via the first supporting device portion. The holding device is held on the second supporting device portion. The first and second supporting device portions are arranged one behind the other in the processing direction and interconnected so as to be movable and in particular displaceable relative to one another in the processing direction.

A soil treatment apparatus for loosening soil, in particular along a processing direction, in particular for soils with lawn growth, includes a support device and a holding device which is preferably movably held on the support device and on which a plurality of injection elements are held, a lifting device by means of which the injection elements are able to be inserted into and withdrawn from the soil, and a fluid supply device which is fluidically connected, directly or indirectly, to the injection elements for supplying fluid. A respective injection element is held on the holding device and able to be inserted into and withdrawn from the soil individually and/or separately and/or independently of the other injection elements.

The present application discloses a rolling lawn aerator, including a perforating device, where the perforating device is capable of rolling on a lawn so as to perforate and aerate the lawn. The perforating device includes a body assembly and a plurality of perforating assemblies, and the plurality of perforating assemblies are arranged in a circumferential direction of the body assembly; and each of the perforating assemblies includes a perforating pipe, and at least a part of a structure of the perforating pipe exceeds the body assembly in a radial direction of the body assembly.
