An active harrow comprises a rotatable cylindrical body on the outer surface of which is mounted a plurality of tines which project outwardly for engaging the ground. The rotatable body is carried in a yoke and supported from a tool bar in a manner which allows the axis of the rotatable body to be adjusted relative to the tool bar. The tines are inclined so that they lie in axial planes but inclined relative to the radial plane of an angle in order of 20° to 30°. Each tine includes a main body portion and an end portion which is cranked. This orientation of the tines provides an effective harrowing action but prevents accumulation of trash.
