Abstract
A forage harvester is provided with a front unit, comprising a rotatable cutterhead to which crop material is fed by feeding apparatus comprising stationary lower feedrolls and movable upper feedrolls. The upper feedrolls are suspended from the feeder frame by a pair of belts, which define the lowermost position of the movable feedrolls, under conditions where no or very little crop is introduced into the harvester. Inevitable accumulation of crop material or dirt on the components of the feeding apparatus will not influence the position to which the feedrolls may be lowered. A steady and even flow of crop material to the cutterhead can hence be maintained, even when little material is introduced.
