摘要： An implement and procedure for reconditioning and aerating turf is disclosed. The implement comprises a frame, a narrow plow member having a concave leading edge with a forward tip depending from the frame, and a pair of narrow blades declining at an angle from the frame and loosely engaging opposite sides of the plow member adjacent its tip. The blades are mounted in a particular manner and are provided with specially-shaped edges designed to provide the desired groove cutting action as the implement is pulled forwardly through the turf. The implement functions to cut and lift slivers of soil and sod and to deposit the same along a groove cut in the turf. Preferably, a series of parallel grooves are formed in the turf in a single pass, the widths and depths being determined by the nature and severity of the reconditioning or aerating problem being treated.

摘要： A frame is provided journalling a rotary shaft having a lever system for rectilinearly driving at least one set of pins into and out of the ground. The lever system has a pair of substantially parallel spaced rods connected pivotally at one end to the set of pins and at the other end pivotally to the frame and offset from each other. The lower rod is extendible in length when the pins are placed under load and automatically resumes its normal length when the load is removed.

摘要： An earthworking implement comprising a frame on which are supported front wheels, rear wheels and a rearmost dolly wheel. An aerator member with blades is rotatably secured to the frame between the front and rear wheels. The dolly wheel is mounted on the frame for rotation about a vertical axis at a location rearwards of the rear wheels. The front wheels and the dolly wheel represent endmost wheels on the frame. One of the endmost wheels is vertically movable with respect to the frame between raised and lowered positions, such that in the raised position the front wheels and dolly wheel define a common tangential plane which is at a level above the blades of the aerator member and below the rear wheels thereby establishing an operative aerating position whereas in the lowered position the front wheels and dolly wheel define a common tangential plane which is at a level below the aerator member and the rear wheels thereby establishing a transport position. A material dispenser can be positioned at the front of the frame for dispensing various materials onto the ground. The dispenser, front wheels and aerator can be power driven.

摘要： Disclosed herein is a soil aerating device including a frame, a hollow cylindrical drum supported from the frame for rotation about a horizontally extending axis and for folling travel along the surface of the ground or turf to be aerated. Fixedly mounted on the exterior of the drum in registry with respective apertures provided in the drum are a plurality of hollow core-forming tines which are arranged to act much like involute gear teeth, while cutting and removing a plug or core from the ground or turf as the drum is rolled over the surface thereof, and to leave a "rack-like" pattern of holes. Each tine includes a pair of generally V-shaped, opposed side walls having an apex located on or near a radial plane extending radially from the drum axis. At least a part of the leading end portions of the side walls terminates in a sharpened cutting edge segment and the trailing end portions of the side walls are connected by a transverse trailing end wall which cooperates with the side wall cutting edge segments to form a generally U-shaped cutting edge.

摘要： A plurality of spring loaded pins is held in a main block which is moved up and down by an eccentric. The base is apertured to receive the pins and if the base is placed on a surface and the block is reciprocated, the pins protrude from the base and retract therein as the reciprocation occurs. If used on a screen type surface, the pins clean the apertures in the screen. The device can also be adapted for use in aerating lawns and the like.

摘要： Lawn-aerating apparatus for punching a multiplicity of holes in terrain comprising an electric motor carried on a wheeled frame and coupled to a plurality of spiker rod elements. In a first embodiment the rotary drive cooperates with a cam mechanism, Which is normally decoupled but which engages when pressure is applied against the tips of the spiker rod elements, to vertically reciprocate the rods at relatively high frequency so as to drive them into the ground. In a modified embodiment the spiking elements are in the form of augers which are coupled by a gear arrangement for common rotation by the motor so as to screw them into the ground. In both embodiments the wheels and frame are carried on a spring-biased suspension which assists in the in-and-out motion of the law perforator as it is rolled along the ground punching holes in the terrain.
