  • Patent number: 6618987
    Abstract: A method of repairing a divot made by a golfer in the grass playing surface of a golf course provides for the golfer to deposit a divot repair body, comprising a growing material such as sand formed into a consolidated mass, into the divot. The body can then be crushed under foot for evenly spreading the growing material in the divot and thereby effectively filling the divot with the growing material. The invention relates also to a divot repair body that can be used in conjunction with the method and that can be carried by a golfer in a suitable package for rendering the employment of the method convenient.
