An electric power rake is employed in use to care for lawns. The electric power rake includes a deck housing, multiple wheels, a handle, a battery housing, an electric motor, a pulley assembly, and a working shaft, among other possible components. The battery housing is supported on the deck housing. One or more battery cavities resides in the battery housing. A battery, such as a lithium-ion battery, is received in one of the battery cavities and powers the electric motor. The electric motor has a shaft that drives rotational motion in the pulley assembly. The working shaft is driven to rotate via the pulley assembly and has multiple blades that revolve thereabout when the working shaft rotates.

Tines (120) of 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 adjacent the outer ends on each of two independently rotatable shafts (102) to which inner tine assemblies (100a, 100b) are rotatably connected adjacent the inner ends of the two independently rotatable shafts (102). Thus, the outer tine assemblies (104) are located intermediate the inner tine assemblies (100a, 100b) and the outer ends of the two independently rotatable shafts (102).

A powered lawn dethatcher with a dethatching mechanism for dethatching lawn, a driving mechanism for driving the dethatching mechanism, and a collection mechanism arranged to collect at least some dust and debris agitated by the dethatching mechanism during operation.

An apparatus for performing a ground treatment, such as aeration or dethatching, is provided. The apparatus includes a base frame component to which a pair of angled side frame components are pivotally mounted. Each angled side frame can include first and second ends that are oriented to form a central angle. A first end of an angled side frame can be pivotally attached to a wheel and/or the base frame component, while the second end can include a mechanism for mounting a ground treatment component.

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.

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.

An apparatus for treating turf, comprising: a cylindrical rotor, rotatable about an axis, the rotor having: a first helical track portion having a first helical track extending about the axis in a first direction from a first end towards a central portion thereof; a second helical track portion having a second helical track extending about the axis in a second direction between a second end and the central portion thereof; wherein each helical track portion comprises at least one helical track having a plurality of teeth arranged therealong.

A dethatcher includes a frame having front and rear ends, a cover coupled to the frame and configured to selectively move between an open position and a closed position, a handle extending from the frame, multiple wheels coupled to the frame, a cutting reel housed in the frame, and an engine for powering a drive mechanism of the shaft. The cutting reel includes a shaft having a first end and a second end, at least one cutting mechanism located between the first end and the second end of the shaft, and the drive mechanism for powering the shaft. When the cover is in the open position, a user may access the cutting reel from a top end of the frame.

A dethatcher includes a frame having front and rear ends and a handle extending from the frame rear end. Wheels are coupled to the frame, and a cutting reel is housed in the frame. An engine is included for powering the cutting reel. In one embodiment, a bottom of the engine is below a top of the cutting reel when the cutting reel is in use. In another embodiment, the cutting reel is located between the engine and the frame front end. Another dethatcher has sequentially from a rear end: a handle, an engine, a cutting reel powered by the engine, and a bagger for collecting debris from the cutting reel.

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.
