ABSTRACT:
To pick up crop or other strewn materials from ground or other level, a bladed rotor is travelled closely over the materials so as to flick them into a carrier bin, a conveyor chute or the like. The rotor blades are of pliant sheet material each fixed by one longitudinal edge to a rotor shaft so as to be able to extend radially from the shaft, under centrifugal force, when the shaft is rapidly rotated; the back or trailing faces of the distal edge marginal portions of the blades are eccentrically weighted so that, upon rotation, the margins are centrifugally induced to incline angularly in the direction of blade rotation so to exercise a spooning or up-scooping action on the matters to be picked up.
