A cylindrical turf treatment rotor (10) adapted to be driven in rotation about a horizontal axis (10a), and provided with wear-resistant teeth (13) extending along one or more helical tracks (14a-14d) on the rotor, the teeth being individually attacked to the rotor so as to be capable of individual removal for replacement or refurbishing or for reconfiguring the rotor.

A stand-on aerator including a chassis, a pair of first wheels coupled to the chassis, wherein the first wheels are operable as drive wheels, a pair of second wheels coupled to the chassis, and an operator platform extending from a rear portion of the chassis. The stand-on aerator also has an aerator assembly coupled to the chassis, wherein the aerator assembly includes a plurality of reciprocating tines capable of extending from and retracting into the aerator assembly.

A power seeder may include a frame, one or more wheels, one or more blades capable of cutting into soil, an engine capable of powering the one or more blades, and a seed hopper. The seed hopper may have an opening capable of dispensing seed located forward of the one or more blades. The one or more blades may rotate in an opposite direction to a forward rotation of the one or more wheels. In some embodiments, the seeder may further include a handle for adjusting the height of the one or more blades, a plurality of interlocking teeth, and a spring. The spring may provide a load to counteract the force of gravity on the one or more blades. The aerator may also include a flap located between the opening and the one or more blades.

In general, the subject matter described in this disclosure can be embodied in an aeration tine that includes a mounting portion removably connectable to an aeration apparatus and defining a central axis; and a curved blade portion that extends longitudinally from the mounting portion to a tip of the aeration tine and that is operable to fracture soil and form an aeration pocket. The curved blade portion includes a concave first edge and an opposed convex second edge, wherein the concave first edge includes (i) a proximal first edge portion, (ii) a distal first edge portion proximal the tip of the aeration tine, and (iii) a middle first edge portion between the proximal first edge portion and the distal first edge portion, the middle first edge portion closer to the central axis than both the proximal first edge portion and the distal first edge portion.

A method for the treatment of turf (11) comprising grass (12) growing in a matrix (15, 16) comprising removing matrix (15, 16) including any thatch and other infestation by blading (18) moving through the matrix (15, 16) to a predetermined depth (d). The method may be used to treat turf (11) reinforced with artificial grass (13). Equipment for carrying out the treatment comprises a bladed rotor (17) rotating about a horizontal axis.

A reseeding device (1) is configured for introducing grass seeds into an existing turf, comprising a rotatable shaft (2) which is provided with a number of blades (3) along its length which are at right angles to the shaft (2) and which are configured for cutting furrows into the turf and loosening and removing parts of the turf, a seed distributor (4) configured for spreading grass seeds at least in the furrows produced, in which the device (1) is configured, in use, to discharge the material loosened by the blades (3) over the shaft (2) and the seed distributor (4), along a direction (A) opposite to the direction of travel, so that the scattered grass seeds are at least partly covered by the loosened material. This reseeding device (1) prevents loosend material from forming an ipediment during reseeding.

A self propelled aerator and fertilizer apparatus 10. The apparatus 10 includes an elongated frame 12, having front wheels 20 and rear wheels 22 coupled to the frame. A steering wheel 30 which controls the front wheels 20 is provided so that the apparatus 10 can be moved in a predetermined direction. An aerator 34 is coupled underneath a lower intermediate portion of the frame 12 for aerating the soil upon rotation thereof when the aerator is moved up and down to selectively engage the soil. A fertilizer 90 is coupled to an upper end portion of the elongated frame 12 so that fertilizer can be dispensed into the soil after aeration is accomplished.

A stand-on aerator includes a chassis, an operator platform extending from a rear portion of the chassis, an aerator assembly coupled to the chassis and having a plurality of reciprocating tines configured to extend from and retract into the aerator assembly, and an object detection sensor. At least a portion of the plurality of reciprocating tines are configured to retract in response to the object detection sensor detecting an object in a path of the aerator assembly.

The aerating-roller attachment for riding lawn mower comprises a roller, a plurality of spikes, and a mounting bracket. The aerating-roller attachment for riding lawn mower may be coupled to a riding lawn mower via the mounting bracket and may aerate a lawn. The riding lawn mower may pull the roller behind the riding lawn mower and the roller may rotate as the riding lawn mower moves. The plurality of spikes may be pressed into the lawn and then withdrawn from the lawn as the roller turns. The weight of the riding lawn mower may force the plurality of spikes into the lawn leaving a plurality of aeration holes such that water, nutrients, and air may penetrate the lawn.

A tine disc comprises a central hub and multiple individual tines extending radially from the central hub, wherein each of the multiple individual tines includes a rib on a surface of the tine, extending from the central hub to a distal end of the tine. In a spike aerator, such tine discs are mounted on a shaft, and the individual tines pierce and penetrate into the soil of the underlying ground surface as the aerator is moved over the underlying ground surface.
