The object was to investigate the flow and energy requirements for chopping fresh water hyacinths. The basic unit tested was an International 350 Forage Harvester. The machine has both a feed mechanism and a cutting unit. For this study the two were powered through separate sources so each could be varied independently. Tests were conducted using various feed rates, lengths of cut, speed of cutting blades, discharge conditions feed mechanisms and sheer bar clearance. The capacity of the forage harvester was more dependent upon the feeding mechanism than the power available to drive the unit. The average horsepower consumed was related to the feed rate expressed in tons per minute by the formula P = 35.2 F + 2. The capacity of the unit could be increased with a different type of feed mechanism.
