PROBLEM TO BE SOLVED: To provide an agricultural implement in which transfer between operation state and non-operation state of rotary operating body can readily be carried out and reduction of impact and noise is performed. SOLUTION: The agricultural implement is equipped with a plurality of driving side-engaging bodies 23 located in the outer end of a driving rotary shaft 21 of a central operation part. The agricultural implement is further equipped with a plurality of driven side engaging bodies 43 located in the inner end of driven rotary shaft 41 of an extending operation part. A buffer 51 enabling elastic deformation is provided in the driven rotary shaft 41. The buffer 51 is put into a space between adjacent driving side-engaging bodies 23 by turning to operation direction of the extending operation part to engage with both driving side engaging bodies 23 and the driving side-engaging bodies and the driven side engaging bodies are kept in non-contact state by the engagement. When the driving rotary shaft 21 is driven and rotated, the driving side engaging bodies 23 are brought into contact with driven side engaging bodies 43 and engaged therewith by elastic deformation of the buffer 51.
