<p>In apparatus for conditioning crops such as grass, two rotors (12, 37) are positioned opposite each other on opposed sides of a passage (14) and engage crop passing through the passage and condition the crop by cooperation between the two rotors (12, 37). Preferably each rotor (12, 37) is a brush having a multiplicity of stiff, resilient, elongate elements (10) which are yieldable in more than one plane in response to engagement by the crop by bending of the elements. The rotors (12, 37) overlap at their outer perimeters and are rotated in contra-rotation with the same peripheral speed. Preferably the brush elements (10) are arranged in transverse rows with the rows of elements (10) intermeshing in the manner of two gear wheels. One brush (12) may form a rotary conveying device for picking up and conveying crop. The conditioning apparatus may be mobile or stationary, and when mobile may include cutting means for cutting crop to be conditioned.</p> |
