Abstract
A forage harvester is provided with a front unit, comprising a rotatable cutterhead to which crop material is fed by stationary lower feedrolls and movable upper feedrolls. The latter are journalled in a pair of bearing housings, connected to load arms, which are linked to crank arms pivotally attached to a feeder frame. Each load arm has a protruding member to which a spring is attached for compressing incoming crop material to an even mat. The springs also push the upper feedrolls rearwardly to compensate the reaction forces from the material flow and prevent excessive wear of the feedroll axles at their passage through the feeder frame.
