PROBLEM TO BE SOLVED: To provide a low-cost field crop pick-up machine capable of preventing scratching and peeling of skin at the time of picking up a field crop on a field topsoil.SOLUTION: A pick-up conveyor 2, in which its front side is inclined downward, is provided at a traveling machine body 1. An auxiliary device 3, in which a soft, long elastic body 31 is folded roundly at the middle and mounted to a rotor 32, is provided at a front upper part of the conveyor. When the machine travels while a part of a front end portion of the pick-up conveyor 2 is embedded in a soil, the elastic body 31 is deformed along a shape of a field crop P and rotated while being in surface contact, and the field crop P makes a smooth transfer to the pick-up conveyor 2 from the topsoil of a field A against resistance of transfer by driving force caused by friction. Thus, the skin of the field crop P is hardly scratched in comparison to a method that compulsory rakes the crop with a tabular elastic body of the prior art. Moreover, since the rotor 32 is a single shaft as well as a simple structure, it is possible to be manufactured at a low cost in comparison to double shafts of the prior art.
