Abstract: A disk for vertically cutting grass surfaces, 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.

Abstract translation: 提供用于垂直切割草坪的盘。 盘包括可安装到轴的中心板和从中心板的圆周边缘延伸的多个齿。 每个齿包括从中心板的圆周边缘延伸的基部和至少一个以偏移角从基部延伸的叶片。 每个叶片包括以偏移角从基部延伸的颈部，以及从颈部相对于中心板的中心平面径向向外延伸的尖端，使得尖端偏离中心平面。 尖端还以相对于中心平面的偏航角度从颈部延伸，使得当盘围绕轴的旋转轴线旋转时，尖端的前缘在与尖端的后缘不同的旋转平面中旋转。
