FIELD: agriculture; engineering.

SUBSTANCE: group of inventions relates to agricultural machine building. Hammer system for shaft of straw chopping machine with fastening hole in cantilever includes rod element, which is made with possibility to pass through fastening hole of cantilever, and protecting from turning element, by means of which rod element is made with possibility of resting against cantilever to counteract the rotation. First hammer with hole is fitted on rod element. First fastening element is connected to the first free end section of the rod element. First disk with hole is set on the rod element so that the first disc is located between the first fastening element and the first hammer. First disc is made radially cut. Rod element by first fastening element is stressed in axial direction relative to longitudinal axis of rod element. Cylindrical envelope of the first fastening element that is coaxial to the longitudinal axis of the rod element has a smaller radius than the opening of the first hammer.

EFFECT: group of inventions provides simple dismantling of all parts of hammer system.
