摘要：
A disk for vertically cutting grass surfaces is provided. The disk includes a center plate mountable to a shaft and a plurality of teeth extending from a circumferential edge of the center plate. Each tooth comprises a base extending from the circumferential edge of the center plate and at least one blade extending from the base at an offset angle. Each blade includes a neck extending from the base at the offset angle, and a tip extending radially outward from the neck relative to a center plane of the center plate such that the tip is offset from the center plane. The tip also extends from the neck at a yaw angle relative to the center plane such that when the disk is rotated about a rotational axis of the shaft a leading edge of the tip rotates in a different rotational plane than a trailing edge of the tip.
