Abstract: A tractor-drawn agricultural implement serving to extract and to shred stalks and roots from a reaped cotton field, comprises a frame mounted on two wheels, on which are mounted a shredder and a blower unit. The shredder is completely enclosed in a casing which is provided with a stalk inlet opening and with an outlet opening connected to the suction side of the blower unit. Two arms are pivotally connected to the frame above the shredder inlet, each arm being provided at its lower end with two obliquely positioned, hydraulically rotated extractor wheels fitted with resilient tires which have their adjoining surfaces pressed together and pull the stalks out of the ground while passing thereover. The implement is characterized by the conveying means serving to grip the extracted stalks and to insert them into the shredder casing.
