Abstract

Cette moissonneuse comprend un premier cadre de support (28) supportant un premier dispositif de refroidissement (21), et un second cadre de support (30) supportant un second dispositif de refroidissement (22). Le premier cadre de support (28) est conçu pour être ouvert et fermé de manière oscillante autour d'un premier axe d'oscillation (Z2) sur une première position fermée dans laquelle le premier dispositif de refroidissement (21) adopte une orientation en fonction de la durée d'utilisation, et une première position ouverte dans laquelle le premier dispositif de refroidissement (21) adopte une orientation ouverte vers l'extérieur dans une direction gauche-droite de corps de machine. Le second cadre de support (30) est conçu pour être ouvert et fermé de manière oscillante autour d'un second axe d'oscillation (Z3) sur une seconde position fermée dans laquelle le second dispositif de refroidissement (22) adopte une orientation en fonction de la durée d'utilisation, et une seconde position ouverte dans laquelle le second dispositif de refroidissement (22) adopte une orientation ouverte vers l'extérieur dans la direction gauche-droite du corps de machine.
