Forage harvester with water injection system

A method for controlling a supply of liquid from a nozzle assembly mounted on a concave of a forage harvester, the method comprising the steps of:

• monitoring a formation of crop buildup at one or more locations along a discharge path of the forage harvester through which a stream of cut crop particles are distributed and discharged from the forage harvester;
• when crop build-up is detected, activating the nozzle assembly on the concave to thereby discharge a liquid in a downstream direction of the discharge path;
• and
• controlling a flow of the liquid so that the liquid ejected from the nozzle assembly impinges on the concave at a location upstream of an impact zone of the stream of cut crop particles onto the concave, and in close proximity to said impact zone.

A method for controlling a supply of liquid from one or more nozzle assemblies of a forage harvester, the method comprising the steps of:

• monitoring a formation of crop buildup at one or more locations along a discharge path of the forage harvester through which a stream of cut crop particles are distributed and discharged from the forage harvester;
• when crop build-up is detected, activating a first nozzle assembly on a concave of the forage harvester and/or a second nozzle assembly on a spout of the forage harvester through which the stream of cut particles is ejected from the harvester, to thereby discharge a liquid in a downstream direction of the discharge path;
• and
• controlling a flow of the liquid so that (i) the liquid ejected from the first nozzle assembly impinges on the concave at a location upstream of a first impact zone of the stream of cut crop particles on the concave and in close proximity to said first impact zone, and/or (ii) the liquid ejected from the second nozzle assembly impinges on the spout at a location upstream of a second impact zone of the stream of cut crop particles on the spout and in close proximity to said second impact zone.
