An aerator mechanism is provided having a rotating cam wheel and a ram link thereattached. A tine positioned at the lower end of the ram link is driven into and out of the ground as the cam wheel rotates. A mounting mechanism operatively couples the lower end of the ram link to the aerator's frame. The mounting mechanism includes first and second linkage members pivotally coupled together between the frame and ram link. A biaser is in constant abutment between the frame and the second link member for returning the linkage to a neutral position when the second link member has shifted in a first direction from the neutral position. A blocker is positioned for abutment with the second link member for limiting the motion of the second link member in a second direction away from the neutral position.
Un aérateur est muni d'une came rotative à laquelle est relié un mandrin. Une pointe fixée à l'extrémité inférieure du mandrin pénètre le sol et en ressort à chaque rotation de la came. La partie inférieure du mandrin et le cadre de l'aérateur sont reliés par un mécanisme de fixation, qui compte deux pièces de raccord réunies par un pivot. Une pièce en biais est constamment serrée entre le cadre et la seconde pièce de raccord pour remettre à la position neutre le raccord lorsque la seconde pièce passe de la position neutre à une première direction. Un dispositif de blocage limite le mouvement du deuxième raccord lors du passage de la position neutre à une deuxième direction.
