<p>A shaft mounted in the machine to rotate on a horizontal axis extending transverse to the travel of the machine carries a plurality of generally radial members lying substantially in a common plane perpendicular to the shaft. A plurality of sod-lifting arms extend axially in the same direction from the ends of the radial members. Each of the arms consists of a substantially flat plate which is L-shaped in outline and consists of a base portion having substantially parallel sides which is attached to the radial member and is raked forward in the direction of rotation and a stem portion having substantially parallel sides which is raked backward.</p> |
