Hackmesser für landwirtschaftliche Hackmaschinen mit sägenartigen Schneiden. Chopping knives for agricultural chopping machines with saw-like cutting edges .

Gänsefußmesser oder Winkelmesser sind mit einseitig angeschliffenen durchlaufenden Schneiden versehen. Diese Schneiden werden während der Arbeit verhältnismässig schnell stumpf, so dass der angestrebte Zweck d.h. das Abschneiden der Unkreutwurzeln nur mangelhaft erreicht wird. Das Unkraut gleitet an den stumpfen Schneiden vorbei, ohne vom Boden getrennt zu werden.Firing refers to the cutting of the chopping knives on agricultural equipment for weed control.
