Movable Obstructions (Rule 24-1)
Movable obstructions (i.e. artificial movable objects such as rakes, bottles, etc.) located anywhere may be moved without penalty. If the ball moves as a result, it must be replaced without penalty.
If a ball is in or on a movable obstruction, the ball may be lifted, the obstruction removed and the ball dropped, without penalty, on the spot directly under where the ball lay on the obstruction, except that on the putting green, the ball is placed on that spot.
