A swath pick-up for a harvester provides a drive for the transverse toothed members which acts to rotate the toothed members about a transverse axis while moving them longitudinally of the axis. The drive comprises a pair of plates arranged at opposed ends of the transverse member each supporting a plurality of pairs of bevel gears mounted such that one bevel gear rotates with the plate while the other is rotated by rotation of the first to rotate the respective transverse member on a crank. The bevel gears are inter-connected either by a shaft or by an elbow casing. The first bevel gear is either fixed to the plate for rotation therewith or is rotated by an internal cam track provided on a cam plate parallel to the rotatable support plate.
