Abstract

The crop-mowing machine has a number of rotary discs on a transverse beam pulled by a tractor etc. across the field. A blower directs a current of air having a velocity component mainly in the horizontal direction, and 1 hing in a theoretical vertical plane extending from one or both of the outermost discs (2) and inwards and rearwards. This plane can have a part concentric with the axis of rotation of the outermost disc. The air can be delivered by a blower (11) via a plenum chamber (7) having a number of discharge slots (8) parallel to the plane referred to. The design collects the mown crop into a single swath.
