Abstract
A soil cultivating implement or machine has a tined rotor mounted on a frame for rotation about an axis transverse to the intended direction of movement of the implement, and with the tines penetrating the ground in use. The tines are arranged to enter the ground in the same sense as the forward movement of a vehicle driving the implement. The rotor is connected to a second tined rotor which rotates faster than the first rotor which rotates in the same direction as the wheels of the vehicle but at a lower peripheral speed than the speed of movement of the implement over to the ground. The ratio of the rotational speeds of the two rotors is between 2:1 and 4:1. Each rotor has a rotor shaft with a plurality of axially spaced mounting flanges, the tines being bolted to the flanges and extending generally tangentially of the rotor shaft.
