A
forage harvester (also known as a
silage harvester,
forager or
chopper) is a
farm implement that harvests
forage plants to make silage.
Silage is
grass,
corn or other plant that has been chopped into small pieces, and compacted together in a
storage silo, silage bunker, or in silage bags. The silage is then fermented to provide feed for
livestock.
Haylage is a similar process to silage but using grass which has dried.
