As soon as the forward speed of the machine exceeds said first predetermined value, the screen tends to lower. The lowering can continue as the speed of advancement of the machine increases, until the screen reaches a limit stop corresponding to a second predetermined value of speed. progress of the machine. As soon as the machine slows down and the speed returns below the second predetermined speed of advance of the machine, the screen moves in the direction of an elevation, until returning to the starting position when the machine is at a standstill or the forward speed of the machine is less than the first predetermined speed value. If the device is equipped with means for locking the screen in the up position, this movement of the screen takes place only when the screen has been previously released.
