ABSTRACT:
The invention relates to an agricultural implement provided with rotary blades (3) which are secured in a changeable manner to at least one blade-carrying flange (2) of a shaft (1). In order to reduce the work and the time for changing the blades, each blade (3) which adheres against one side of the blade-carrying flange (2) is secured to same by means of one single locking bolt (5, 6) and presents a locking shank (203) which passes through a corresponding opening (4) of the blade-carrying flange (2) and adheres against the other side of same.
