Abstract
A weed control system for a body of water can include a rotatable vertically oriented shaft mounted proximate the body of water; an elongate horizontally oriented support member mounted to the vertically oriented shaft and suspended over the water; a rake suspended from the support member by a flexible line; and an oscillating motor for rotating the vertically oriented shaft and the elongate support member such that the rake moves in a repeating pattern through the body of water.

A weed control system for a body of water, the system comprising:
- a rotatable vertically oriented shaft mounted proximate the body of water;
- an elongate horizontally oriented support member mounted to the vertically oriented shaft and suspended over the water, wherein the support member is cantilevered from the vertically oriented shaft;
- a rake suspended from the support member by a flexible line;
- and
- an oscillating motor and gears for rotating the vertically oriented shaft and the elongate support member such that the rake moves in a repeating pattern through the body of water.
A method to control weeds for a body of water, the method comprising:
- mounting a rotatable vertically oriented shaft proximate the body of water;
- attaching an elongate horizontally oriented support member to the vertically oriented shaft such that the support member is cantilevered over the water;
- suspending a rake from the support member by a flexible line;
- and
- moving the support member back and forth using an oscillating motor such that the rake moves in a repeating pattern through the body of water such that the rake repeatedly contacts any weeds in a path of the rake.
A weed control system for a body of water, the system comprising:
- a vertically oriented shaft mounted proximate the body of water;
- an elongate horizontally oriented support member mounted to the vertically oriented shaft and suspended over the water, wherein the support member is cantilevered from the vertically oriented shaft;
- a rake attached to the support member and extending downward towards a bottom of the body of water;
- and
- a drive member configured for rotating the elongate horizontally oriented support member such that the rake moves in a repeating pattern through the body of water.
