The invention relates to a feeding device (32) for a field chopper (10), comprising:
at least one rotatable lower feedroll (34, 35),
at least one rotatable upper feedroll (36, 37), between which a windrow can be fed and led to a chopping device (22),
and an external force-activated adjustment drive (68), with which the position of at least one of the feedrolls (36, 37) can be changed relative to the other feedroll (34, 35).
It is proposed that a spring (58) be arranged between the adjustment drive (68) and the feedroll (36, 37) that can be moved by this drive.
The spring (58) enables the movable feedroll (36, 37) to react more quickly or immediately to sudden changes in windrow height independent of the inertia of the adjustment drive (68).
