The tractor has a cab with its windscreen (7), top mounted to rotate about a horizontal axis (XX'). A pair of supplementary screens, or a lower frame (13) similarly rotate about an axis (ZZ'), on the lower windscreen frame. The lower frame, or supplementary screens, may rotate through 180 degrees, to contact the internal windscreen face. Fixings may be provided to maintain this lower frame in this folded position, against the windscreen interior. The main windscreen pivots up through approximately a right angle. This provides easy front access.
