The invention relates to a tilling wheel likely to be mounted freely and rotatably on an axle fixed to the frame of a plough, said axle being inclined with respect to the feed direction of the plough in order to impart a rotational motion to said wheel when the plough is moved. The circumference of the wheel seen in parallel to its rotational axis (16) takes the form of a blade (13) of which the leading edge (14) moves gradually away from the axle (16) as it rotates in the same direction as the tilling wheel while in use. |
