ABSTRACT:
A hub and tine assembly for a rotary debris remover is provided which comprises a hub which is rotatable about a shaft and a plurality of tine members which are arranged symmetrically around the rotation axis of the hub. The tine members are pivotally connected to the hub at locations which follow a circular rotation path around the rotation axis of the hub when the hub is rotated. Each tine member has at least one tine which projects from the hub. The tine member has a centre of gravity which is located so that the tine is offset from the radial direction when the hub is rotated and displaced in a direction which corresponds with the direction of rotation so that the tine can effect a "punching" effect on debris in its path.
