Abstract
A weed remover for removing weeds and preventing the growth of new weeds on the bed of a body of water. The weed remover comprises a housing a motor, a drive chain, and a roller having a plurality of fins attached thereto. The motor drives the drive chain which in turn rotates the roller. When the roller is rotated, the fins dig into the bed of the body of water, causing the roller to roll along the bed. The housing is attached to a dock such that it can rotate about a generally vertical axis, permitting the roller to roll in an arc. The direction of rotation of the roller can be reversed such that the roller reciprocates over substantially the same path.
