An agricultural machine is described with a screen for protecting a part of a
cooling system of a motor mounted on the agricultural machine, the screen being
mounted in its operational position adjacent the cooling system, wherein the screen
is movable from the operational position next to the cooling system of the motor
to a position in which the screen lies outside the envelope defining the outer
form of the agricultural machine, the screen being hingedly connected to the agricultural
machine so that the initial trajectory of the screen is horizontal and substantially
perpendicular to the longitudinal axis of the agricultural machine, and that a
further second trajectory of the screen is horizontal and substantially circular,
having its centre of curvature on or adjacent a first hinge position.
