997,616. Agricultural implements. M. EGRETIER. Oct. 14, 1963 [Oct. 15, 1962], No. 40518/63. Heading A1B. An agricultural implement for working the soil between successive plants in a plantation of the kind in which the implement 1 is deviated laterally when a feeler rod 19 is swung aside by the stock 25 of a plant is characterized in that the lateral displacement of the implement is positively effected by a continuously rotating shaft 10 through a cable 14 wound on the shaft 10 and controlled by the feeler rod 19. Movement of the feeler rod 19 tightens the cable 14 on the shaft causing the shaft 10 to act as a capstan to move the plough beam 2. The beam 2 is returned by a spring 6. A sheath 15 is placed on the cable 14 and is secured by a clamp 22.
