CA 2581971

An apparatus and method are disclosed for efficiently removing a belt from a drive assembly of an agricultural implement in which a flywheel and a header framework cooperatively define a gap therebetween which is smaller than a cross- sectional dimension of the belt and thereby prevent the belt from being simply passed through the gap and removed from the remaining components of the drive assembly. A radially inwardly extending notch in the periphery of the flywheel is configured and dimensioned to allow a portion of the belt to be received within the notch. The notched flywheel, with the portion of the belt received in the notch, is rotatable such that the portion of the belt is moveable past the gap to thereby permit the belt to be removed from the remaining components of the drive assembly in the distal direction without requiring the removal of either the flywheel or the framework.

Méthode et dispositif permettant de retirer la courroie d'entraînement d'un matériel agricole dans lequel un volant et un cadre d'organe de coupe forment, ensemble, un interstice plus petit que la section transversale de la courroie, empêchant cette dernière de passer à travers l'interstice et d'être retirée des autres composants du mécanisme d'entraînement. Une encoche faisant saillie radialement vers l'intérieur est aménagée et dimensionnée sur le pourtour du volant de manière à recevoir une partie de la courroie. La partie du volant à encoche sur laquelle repose la partie de la courroie pivote, ce qui permet de faire glisser la partie de la courroie au-delà de l'interstice et de retirer la courroie des autres composants du système d'entraînement, dans le sens opposé, sans avoir à déposer le volant ou le cadre.
