A rake wheel attachment for a harvesting machine such as a cylindrical baler comprises a wheel for engaging and moving crop material laterally of the path of the baler. The wheel is rotatably supported by a wheel support and is pivotably mounted on an arm attached to the machine about the axis of the arm which is generally perpendicular to the axis of the rotation. The rake wheel is biased into an operative position by a spring connected between the wheel support and the arm. The spring is yieldable to permit the wheel to pivot about the arm axis responsive to the engagement of the wheel with a rock or other foreign bodies.
