  • Patent number: 5842331
    Abstract: A weed remover includes a pivoting arm connected to a wheeled chassis, and a rotary wire brush attached to the forward end of the pivoting arm. A belt is positioned to encircle a wire brush pulley coaxial with the wire brush, and a drive pulley driven by a motor. The wire brush can be raised off the ground or lowered to engage it by moving a lever connected to the pivoting arm. When the wire brush is in the raised position, the pulleys are close together and the belt is relaxed, so that the belt is disengaged from the pulleys, and the wire brush is deactivated. When the wire brush is in the lowered position, the pulleys are moved apart, and the drive belt is pulled taut therebetween, so that drive is transferred to the wire brush. The wire brush is spun at high speed to remove weeds growing from cracks on a hard ground surface, such as a sidewalk or driveway. The wire brush is stiff enough to remove the weeds flush to the ground surface, but compliant enough to not harm the ground surface.
