Abstract:
1. An agricultural machine 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 substantially perpendicular to the longitudinal axis of the machine and 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, wherein said screen is 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, further comprising an elongate support member, the support member being hingedly connected to the agricultural machine at one end of the member by a first vertical hinge at the first hinge position and the screen is hingedly connected to one other end of the support member via a second vertical hinge between the screen and the member at a second hinge position, wherein the second hinge position is offset from the centre of the screen, the first hinge position is in front of or behind the operational screen position with reference to the longitudinal axis of the machine, the motor, a part of the cooling system and the screen are arranged along the longitudinal axis of the machine and part of the cooling system is a radiator, further comprising a fan mounted in-line with respect to the motor, the part of the cooling system and the screen and further comprising a guide member, the guide member being hingedly connected to the agricultural machine at one end of the member by a third vertical hinge at a third hinge position and the screen is hingedly connected to one other end of the guide member via a fourth vertical hinge at a fourth hinge position, the lines joining the first and second hinge positions and the third and fourth hinge positions being substantially parallel when the screen is in its operational position.
