An agricultural machine, comprising a feed passage for stalk products; a cutting device provided on said feed passage and having a plurality of turnably supported knives which are arranged in a row and extend in their cutting position into said feed passage; spring loaded knife levers which hold said knives in the cutting position, so that under the action of a foreign body said knives can turn against a spring loading from said feed passage; a joint transverse with which said knife levers are displaceably connected through hingedly connected rods; a frame which is downwardly turnable to a fixed abutment and in which said cutting device is arranged, said frame having side walls provided with slot guides, said traverse being displaceably received at both ends of said traverse in said slot guides of said side walls of said frame so that during a displacement of said traverse with said ends in said slot guides said knife levers of said cutting device are turned from an operative position to an inoperative position and vice versa; and a cylinder-piston unit engaging said traverse.
