A lawn care trailer system that is versatile, that is easily assembled and disassembled, and that is easily controlled during use. The system is supported by wheels and has a frame assembly with spaced apart longitudinal bars and a plurality of transverse bars to form a rectangular platform for supporting a mounting assembly for supporting storage containers and tools; or a box shape support assembly; or a flat-screened bed assembly. Tubular members of the frame assembly attach one or more roller units thereto and a tow bar assembly attaches the frame assembly to a tractor or lawnmower. The frame assembly supports various components making the lawn care trailer system suitable for spring, summer, and/or fall operations.

A ground aeration device comprising: an air supply connector for receiving pressurised air from a source; a supporting element for supporting a drill element for insertion into the ground and a pneumatic hammer for hammering the drill element into the ground; a first pneumatic means comprising a first actuating means for actuating the pneumatic hammer; and a second pneumatic means comprising a second actuating means for controlling supply of the pressurised air through the drill element.

Optional attachments, such as a drop seeder and a sprayer unit, can be removably attached to the front plate of a turf aerator. The attachment includes a hitch slideably received in a tubular receiver and pinned therein by a pin. A lock is pivotal relative to the attachment from an unlocked position to a locked position with the front plate received in slots of the lock. The lock is pivoted relative to the attachment by a rod which is threadably received in the hitch. Valve openings in a valve plate are aligned or mis-aligned with lower openings formed in a hopper mounted to the hitch by a linear electric actuator. A lever is pivotably mounted to a housing which is removably attached to the chassis of the turf aerator and activates the linear electric actuator and a switch controlling an agitator. A valve is alternately in fluid communication with a spray nozzle mounted relative to the hitch and a spray wand. A switch mounted to the chassis is electrically connected to a motor driving a pump in fluid communication with a tank and the valve.

A core recovery vehicle for recovering cores from turf which includes an elongated chassis having elongated sides and a front and a back. 1.sup.st and 2.sup.nd V-shaped wipers are carried on the chassis in a substantially horizontal orientation proximate to the front of the core recovery vehicle whereby the 1.sup.st and 2.sup.nd V-shaped wipers funnel cores from an open front to an apex opening of each V-shaped wiper; and 1.sup.st and 2.sup.nd elevators substantially aligned respectively with the apex opening of the 1.sup.st and 2.sup.nd V-shaped wipers, the 1.sup.st and 2.sup.nd elevators are substantially aligned with and have substantially all major parts thereof coincident respectively with 1.sup.st and 2.sup.nd substantially vertical virtual parallel spaced apart planes substantially aligned with the major axis of the chassis.

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.

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.
