A golf green repair tool having a plurality of spears centered around a plurality of tines. The tines and spears are biased by a spring inside a housing and sleeve. When the cap the housing is pressed by the foot of a greenskeeper or golfer the spring is compressed forcing the tines and spears into the turf. The tines are inserted around the periphery of the ball-mark to aerate and loosen the turf. The spears are inserted into the center of the ball-mark and aerate and pull the bottom of the ball-mark to the level of the surrounding turf. The bottom side of the ground-contacting sleeve pressed down the raised rim of the ball-mark correcting the entire ball-mark to the level of the surrounding turf.

An apparatus for removing weeds from the ground is described. The apparatus comprises an elongated shaft assembly with a top end attachable to a rotary driver; a helix mounted at a lower end of the elongated shaft, the helix shaped and sized to capture weed root material; and an anchoring structure assembly. The elongated shaft assembly is secured within the anchoring structure assembly and is able to rotate and translate longitudinally with respect to the anchoring structure assembly. The helix, when rotationally driven by the rotary driver, threads into the ground around the weed root material to capture the weed root material for removal from the ground.

A tool for exterminating subterranean burrowing animals, such as moles and voles, said tool includes a half inch thick square steel base plate that is about is about 4.5 inches by 4.5 inches, and a steel handle that is about 44-48 inches long is perpendicularly welded to a top central surface of the base plate. The handle has a grip covering an upper end of the handle and extends down the handle at least 12 inches. The ratio of handle length to base surface area is about 2.17 to 2:37. The invented tool weighs 9.5 plus/minus 0.5 lbs.

In one aspect, the present disclosure involves a re-aeration device and re-aeration method for constructed wetland. In one aspect, the re-aeration device comprises a re-aeration pipe and a windmill. The re-aeration pipe has a tubular structure with openings at both ends; one end inserts into the wetland substrate, and the other end connects with the windmill for receiving and accelerating air flow. The re-aeration pipe may also contain several telescoped or parallel arranged pipes with openings at both ends as well as with different pipe diameters and lengths, which connect with the windmill to form the re-aeration device. The present disclosure also provides a method of re-aeration for constructed wetlands by using the above-mentioned device. The re-aeration device provided herein has features of being simple in structure, environment friendly, and low-cost. In one aspect, the re-aeration method is characterized as simple, practicable, energy-efficient, environment friendly, low-cost, widely applicable, and having good effect and high performance on re-aeration.

A leaf rake includes a handle having an elongated body with a first end, a medial portion, and a second end, and a head assembly including a base portion and a handle coupling, the handle coupled to the head assembly by the handle coupling. The head assembly includes a first and a second set of tines unitary with the base portion, wherein each tine of the first and second set of tines includes an elongated body having a first end, an offset portion, and a distal second end, wherein the offset portion of the first set of tines is disposed on a first side of the base portion and wherein the offset portion of the second set of tines is disposed on the first side of the base portion. A shrub rake including a coupling, a base portion and a number of tines is selectively coupled to the head assembly.

A multi-function service tool capable of creating numerous size cavities in the soil with the deployment of one or more various size cavity cutters attached to the tool t-handle. This modular flexibility concept allows service technicians of various industries and others to deploy a single configured tool, that contains specific attachments, to complete their various assigned service tasks.
