Abstract: A green cores collecting apparatus attachable to the rear portion of a corer vehicle comprising a housing provided with a upper laterally extending rotary shaft, a lower laterally extending rotary shaft arranged in parallel with the upper rotary shaft and a rotary elevator located between the upper and lower rotary shaft, the housing being backwardly tilted, and being further provided with a dirt ejecting aperture at its upper rear portion and a soil receiving aperture at its lower front portion, an engine being attached to the housing for driving the rotary elevator and a pair of fitting arms being rotatably fitted to lateral sides of the housing by a pair of shafts so that the fitting arms project forward and at least one of the shafts is removable. Since the fitting arms are securely fitted to the lateral sides of the green corer vehicle locking bolts, the rotary elevator automatically starts its operation as soon as the engine is started.
