A vehicle combining the attributes of a tractor and a utility vehicle includes a three point linkage and other locations to which a plurality of attachments for performing grooming or working operations on a ground or turf surface may be couple. The vehicle includes a front mounted engine, a mid-mounted operator compartment and a rear mounted bed or box. A PTO shaft and/or a hydraulic power system of the vehicle power attachments that require power. A control system and a visual display and data entry device linked thereto are provided for allowing an authorized person to setup, store and thereafter use an operational profile for each attachment that is to be coupled to the vehicle. In a rate dependent attachment, the control system maintains the ground speed and the attachment implement in a fixed ratio. A down/up control is used to signal the start and end of an operational sequence to the control system.

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 on independently rotatable shafts (102) to which inner tine assemblies (100a, 100b) are connected. A tine cover (50) removably closes an opening (40) in the top plate (28) and in which weights (70) are removably received over the tine assemblies (100a, 100b, 104). Transport wheels (134) are moveable by pivoting a stop plate (140) to position an upper pivot axis (150a) of an abutment bar (150) ahead of or behind the stop axis (142) and lower pivot axis (150b). A stop (146) positioned on the stop plate (140) without the use of tools adjusts the depth of the tine assemblies (100a, 100b, 104).

An electric power lawn aerator is employed in use to care for lawns. The electric power lawn aerator is battery-powered, and includes a frame assembly, one or more non-driven wheels, a handle assembly, a powerhead assembly, a powertrain assembly, and a tine assembly, among other possible components. The powerhead assembly has one or more battery cavities and an electric motor. A battery, such as a lithium-ion battery, is received in the battery cavity(s) and powers the electric motor. The electric motor imparts rotational drive to the tine assembly by way of the powertrain assembly. The tine assembly punctures the lawn amid use of the electric power lawn aerator.

An apparatus for surface treatment and collection of undesirable debris from lawns. During a cutting operation, rotating blades ripe surface material from soil up onto a filtering screen and along this further to a collecting box so that only stones and debris of e.g. at least 1 cm enter the box whereas smaller particles/soil escape through the filter screen and are thereby returned to the lawn surface, which significantly increases the nutrient level in the upper layers of the lawn.

A method of stacking dethatchers includes pivoting an upper portion of a handle on a first dethatcher toward a front end of a frame on the first dethatcher, upon pivoting the upper portion of the handle toward the front end of the frame, exposing a rear support point defined by a lower portion of the handle, and stacking a second dethatcher on the first dethatcher so that the second dethatcher is supported on the rear support point defined by the lower portion of the handle and a front support point defined by the upper portion of the handle.

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.

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.

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.
