Abstract: A process for conditioning a golf green which preferably is constructed in accordance with the specifications of the United States Golf Association. In this process, air is blown at a flow rate of from about 250 to about 1000 cubic feet per minute onto the top surface of the golf green while simultaneously withdrawing air from said vent side of the main feeder line at a flow rate of from about 250 to about 1,000 cubic feet per minute.

Abstract: A process for raising a sunken, in-ground sprinkler is provided. In the first step of this process, which is especially useful with pop-up sprinklers, the area around the top of the sprinkler is first cleared. Thereafter, the motor compartment structure and the rotatable sprinkler head are removed from the sprinkler housing. A circular sleeve adaptor is then attached to the sprinkler housing, and a threaded shaft is then attached to the adaptor. A support platform, with a hole in its middle, is then placed over the sprinkler, and one end of the threaded shaft is placed through the hole. A wing nut is then attached to the threaded shaft, and the rotation of the wing nut causes it to contact the top of the support platform, thereby raising the sprinkler assembly.

Abstract: A process for preventing the spread of vegetation from one area to another is disclosed.In the first step of this process, a vegetation-encroachment barrier is provided. The barrier preferably contains two halves which are joined at their bottoms, whose tops are normally touching each other, but whose tops may be separated from each other. The two halves of the device are so shaped that, when their tops and bottoms are contiguous, a chamber between them is defined; the chamber exists at a location intermediate the tops and bottoms of the halves.In the second step of the process, a furrow is dug around the area to be protected. Thereafter, the barrier is inserted into the furrow.

Abstract: A blade assembly for cutting herbaceous terrestrial vegetation at a cutting speed of from about 1,000 to about 10,000 revolutions per minute, wherein said blade assembly is comprised of a U-shaped blade which has a Rockwell C hardness of from about 37 to 40, a flare resistance of less than about 15 degrees, and a bending resistance of less than about 5 degrees, and wherein said U-shaped blade is an integral, symmetrical member comprised a vertically-extending left cutting edge, a vertically extending right cutting edge, and a rotating support member connected to said left and right cutting edges, wherein:(a) said left cutting edge, said right cutting edge, and said rotating support member are integrally formed into a substantial U-shaped structure,(b) each of said left cutting and right cutting edges forms an angle with said rotating support member of from about 90 to about 95 degrees,(c) said U-shaped blade is from about 2.0 to about 15.0 inches long, from about 1.0 to about 3.
