The invention discloses a vibration-reduction light fodder chopper capable of safely cutting materials without vibration. The vibration-reduction light fodder chopper comprises a chopper body, a handle, a dynamic vibration absorber, a handle cover, a sliding plate, a bottom plate, a feeding knife holder, a discharging knife holder, a feeding tabletop, a knife shaft, a torsion spring, a flat washer, a nut, an adjustment sheet, a locking system, a bolt, an elastic washer and a sleeve. The dynamic vibration absorber comprises a steel wire and two mass blocks and is used for reducing vibration of the handle, a blade of the feeding knife holder is curved, materials can be stopped from moving forwards in a phased manner, cutting efficiency is improved, the torsion spring controls the included angle between the chopper body and the feeding knife holder to range from 45 degrees to 60 degrees when external force is not applied to the chopper body, and the chopper body does not need to be lifted by manpower. The vibration-reduction light fodder chopper is simple in structure and convenient to use. The materials are cut by the chopper, vibration is reduced based on meeting cutting functions, hand vibration is avoided, people feel light and effortless when cutting the materials, and the cutting efficiency can be improved.
