Forage harvester

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.
