Flexibility in forage harvesting is a key factor for success with high-performance forage harvesters. The Respiro belt windrower technology makes it possible to produce ideal swath sizes for all harvesters. The high-performance forage harvester in particular needs a full drum to ensure perfect cutting quality and output. The saving in harvesting costs of up to 50% is a welcome factor. In addition, diesel consumption is reduced and the soil is protected by far fewer passes. The best forage quality is placed on the swath - the indispensable basis for top dairy farms.
