Abstract
An improved cutter wheel that is useful in conjunction with tilling apparatus for sod seeding purposes. The wheel has a body fashioned from sheet metal. The periphery is characterized by smooth contours which define the teeth and gullets. The wheel is devoid of hooked sections or notches as well as abrupt gullets where stringy material such as Bermuda grass could become caught or hairpin to cause wrapping. Different teeth are offset in opposite directions from the plane of the body to increase the effective cutting width. Additionally, the symmetry of the cutter wheel is such that it can be mounted for rotation in either direction.
