  • Projection sequencing can be managed by a microprocessor.
  • a nozzle is pivotally mounted about an axis disposed substantially in a width of the mobile machine.
  • a nozzle can be driven, during a projection phase, in pivoting about its axis between two extreme positions, the direction of projection by said nozzle of the above substance on the spreading surface is distant from the mobile machine by relative to said nozzle, in one of these positions and directed towards said mobile machine in the other of these positions.
  • a nozzle can in particular pivot, during a projection phase, from one to the other of its two extreme positions with a direction of pivoting coinciding with the direction of movement of the mobile machine.
  • an actuator pivots at least one nozzle via a universal joint and is associated with positioning adjustments at the end and at the start of pivoting;
